Color Management Made Simple – How to Calibrate your Monitor

Bora Bora, French Polynesia, by Paul Timpa

Color management is one of those topics that is important to understand so that you can get prints that match what you see on your computer screen, yet a lot of what is written on how to do it is overly complicated or deals with technicalities that aren’t necessary in most real-world scenarios.  The goal of this article is to help you understand what color management is and why it’s necessary, and most importantly to tell you how to do it so you can get great prints.

First, let’s understand some concepts.  As usual, I’m going to provide some analogies and stories.  Hopefully this makes it more fun and easy to understand. 

OK, so we’ll start with color temperature.  You may already be familiar with this to some degree because it relates to the White Balance settings you may have on your camera – settings like “Cloudy” or “Tungsten” or “Fluorescent”.  Those settings deal with color temperature, or the color of light.  The next paragraph will explain what it means, and after you’re done reading it, you’ll probably say, “Oh, that’s it!?  That’s easy!”

The reality is that there really is no “correct” color for anything in this world, because it’s impossible to see something’s “correct” color.   Why?  Because everything we see with our eyes is completely affected by the viewing conditions at that moment, meaning the lighting at the time we’re looking at something.  Let me give you an example that will help make this perfectly clear.  This example will also be used later to explain why people’s prints don’t look right.  Here’s the example: 

Let’s say it’s summertime, and I have a nice summer tan going.  One day, I drive to the local gas station, walk into the mini-mart to pick up some snacks, and I pass a mirror.  The lights are that bright, greenish, hideous fluorescent color that you see in gas stations.  I’m shocked when I look in the mirror.  I look horrible, pale, and sickly.  Is that my “correct” skin color?  So, later that same night it’s my birthday party in my house, time to have cake, they turn out the lights, and I lean in to blow out the candles.  My skin by the light of the candles is a glowing orangey, candlelit color and smooth.  Is that my “correct” skin color?  Finally, I wake up the next day to go for a sunrise walk on the beach.  As the sun slowly comes up over the horizon my skin is reddish/golden, and brightly lit.  I think you get the point.  Which of those is my “correct” skin color?  The answer is all of them – my skin didn’t change at all – just the viewing conditions.  In each one of those scenarios, the color of the light was different – not my skin.  The color of the light is measured in temperature, so that’s why you hear the phrase “color temperature”.    The gas station’s fluorescent light is a particular color temperature, and candlelight is a different temperature.  We don’t need to get into any more detail than that… that’s really all we need to know for now.  So back to our examples:  Let’s say you have a picture of your family in your wallet.  You bring it over to my house.  For whatever reason, I’ve decided to have only red light bulbs in my house.  You look at the picture in my house and with all my red light bulbs, the whole photo looks red.  Would you say the photo itself suddenly has a red color cast?  Of course not.  Or if I had only one small lamp in my house, and it’s so dark in there that we can barely make out the details in your photo, would you say your picture is dark and underexposed?  Again, of course not.  It’s all about the viewing conditions.  Understanding this very simple concept is 90% of understanding color management.

So let’s talk about why your pictures may come out dark or orangey when you print them, even though they look great on the screen.  We already said that in the “real world”, what you see with your eyes is dependent on the lighting, color temperature, and viewing conditions at the time.  Well what you see from output devices (meaning printers, computer screens, etc.) is also dependent on how they handle color temperature and light.  And you know what?  Just like my skin may look different under the green fluorescent light in the gas station vs. how I look under candlelight, printers and computer screens have those same color differences when you look at photos.  As a matter of fact, your computer screen displays photos as if they were under the light of of the gas station while printers are more like the candle light.  So how does this cause poor prints?  It’s simple.  I’ll explain: 

Let’s say you’re with your friend and you’re on your way to a birthday party.  You stop off at the gas station to pick up some soda.  Your friend sees herself in the mini-mart mirror under the awful gas station lights and she’s horrified at how pale and sickly she looks.  She can’t believe she’s going to a party like this so she runs over to where they have the make-up,  she buys some self-tanner and bronzer and slathers it all over her face.  She loves the look once she's finished because she's back to her normal sun-kissed complexion and looking great.  It’s really bright in that gas station and she notices some bright spots on her forehead and nose, so she buys some powder and blots down the bright spots with a load of powder.  Perfect.  You leave the gas station and head to the birthday party.  It’s a small party, completely lit by candles.  Your friend?  She looks terrible at the party.  She’s looks a deep shade of dark orange from applying too much self-tanner in the gas station, and she has pounds of powder covering the bright spots.  Under the candlelight of the party, she's way too orange now.  It’s a disaster.  THAT’s what happens to your prints.  You see, in your friend’s case, she was viewing and correcting her skin in the gas station under unusual lighting.  She overcompensated for the pale green light in the mini-mart by over-applying self-tanner and darkening her skin.  But as soon as she left the gas station, she looked ridiculous.  That’s exactly what’s happening to your prints.  Your computer screen is that gas station lighting, and your printer is the candlelit party.  So you must  edit your photos using the proper viewing conditions.  Otherwise what you wind up doing is editing, tweaking, and changing the color and brightness of your photos on your computer, that you plan on printing – but you’re overcompensating for the unusual light of your screen and in fact ruining your images.  These problems are what color management and color calibration aim to correct.  Hopefully these two simple paragraphs have made a light bulb go off in your own head and you’re saying, “Ah, now I get it.”

OK, so now that we know what the problem is, what’s the solution?  The solution is color calibration.  So what is that?

Well we already said earlier that your computer screen is colored more like the lights in a gas station, and that printers are more like candlelight.  So we need to get them in sync.  That’s ultimately the goal of color calibration – to sync up the “viewing conditions” so that everybody is editing and printing their pictures under the same exact lighting conditions.  Let’s get back to our example with your friend and the birthday party.  At the birthday party you were all hanging out in a room where there were exactly ten candles.   Well if you had a room in your own house and you put ten candles in there, the room in your house would have the same lighting as the party.  So you could have your friend apply her make-up in that room, and she’d know that she’ll look exactly the same when she gets to the party.  That’s color calibration.  It’s syncing up the lighting conditions.  In our example, we need to change the color of our computer screen to look less like a gas station and more like candlelight.

How do you do it?  It’s pretty simple – you buy a gadget that does it for you, called a color calibrator.  You strap it to your computer screen and it takes a look at the colors your screen displays.  It then “reaches into” the video card in your computer and changes the colors for you, to match the colors that standard printers use.  That’s the basic process.

OK, before I go any further, I want to tell you that when it comes to color calibration, there are many different opinions on the best way to do it.  This is a hotly debated topic among people, as everybody has their own way.  I’m giving you my method, and it’s a way that works for me.  So on with the show…

First, you need to buy a color calibrator.  I use a product called the Spyder 3 Pro, made by Datacolor.  You can find it at B&H or any photo store.  There are a few brands out there, feel free to shop around and compare features and prices.  I’ve been happy with the Spyder.

Before you calibrate the monitor, there are a couple of things you should do.  Firstly, I recommend you do it at night in the pitch black with all the lights in the room turned off.  You don’t want any lights or colors interfering with the calibrator as it takes its readings from your computer screen.  *You could get strange colors if you calibrate during the day.*

Secondly, and one of the most important things in this entire article – turn down the brightness of your monitor, and memorize where you set it.  One of the most frequent problems that people see in prints is that they’re too dark.  This is because their monitors are too bright.  A picture that looks great on a screen that is too bright will likely print out too dark.  The calibrator will fix the brightness of your monitor “to a degree” (explained later) but you must turn down the brightness on your monitor.  I set my monitor to exactly two-clicks down from maximum brightness.  I memorize this, because when my computer reboots it can reset the brightness to maximum, and I need to know where to put it back.  Once you’ve turned down the brightness on your monitor and memorized where you set it, turn off all the lights in the room and run the software that comes with the calibrator.  The software will probably ask you to set two options – these are the options where you can fine tune the brightness/contrast and the color temperature.   They are called “gamma” and “white point”.   It’s not necessary to understand the technicalities of what they mean.  Just know that the gamma is for the brightness & contrast in the photo, and the white point is for the color temperature (like we described before).  If it gives you the options, I suggest a gamma of 2.2 and a white point of 6500K.  I’ve found that a white point of 6500K gives the most accurate colors to help match what you see on screen to what you get in print.  Once those are selected, you’re all set.  At this point, you can start the calibration and let the product do its thing. Your computer screen will cycle through a bunch of colors and gray patterns, and the calibrator will read the information.  When it’s done, you’ll instantly see all the colors on your monitor change!  You’ll probably see that it got a bit darker, and that the colors are now more orangey.  This is exactly what you want because now your monitor matches what will come out in prints.  For many people, you’re done!  Congratulations.  Using the calibration settings that were just saved on your computer, you’ll be on your way to getting prints that match what’s on your screen.  I’ll get into a few more steps in a moment, but for many people, the hard part is over.

So what’s next?  Well, now it’s time to get some test prints to see how you did.  If you have your own printer, you can print some right away and compare them to the screen to see how well they match.  If not, send some out to your favorite lab and see how they come back.  How you go about checking your prints, and how you send them to the lab matters, so let’s talk a little bit about this.  Firstly, when you check your prints against the screen, you have to do it in the right light.  Remember earlier in this article when I used an example about having all red light bulbs in my house and looking at a friend’s family photos?  They all looked red because the light bulbs were red.  Well this is exactly what you want to avoid when checking your photos for accuracy.  You want to do it in a relatively “neutral” light – meaning not too orangey (like candles or soft light bulbs) and not too green (like fluorescents).  I prefer to check my prints during the day, with the lights off, with the photos only lit by the light coming in from the windows.  I find the light in a room coming in through windows to be pretty neutral for checking prints.  I may then turn on a light or two to check as well.  The print should look good in both types of light.

Regarding sending your photos to the lab, there is something to keep in mind.  In some cases (many cases!), the photo lab has a person who sits there and color corrects your photos to what THEY think you want them to be.  Clearly this is not what you want, because there can be inconsistencies if you get “John” one day tweaking your photos and “Jim” some other day, and he has a different opinion of what your photos should look like.  I suggest you find a lab that offers the option called “No Color Correction” which means that nobody is going to touch the color of your photos.  What you send them goes straight to the printer.  This is what you want if you want consistent photos.  *If your lab does not offer this option then you have no way of ever getting consistent color in your photos.*

So your test prints are back from the lab, you rip open the envelope and take a look.  Hopefully the prints look much closer to what you have on screen now.  If they're still a bit off, you can do a little tweaking.  Adjust the settings, re-calibrate, and then see if the screen matches better.  For example, if the prints came back and they’re still too dark, then your monitor is probably still too bright.  Lower the brightness even more until it matches the test prints you have in your hand.  It may seem ridiculous to have your monitor that dark, but what you’re trying to do is to sync up the monitor with the printer.  You see, what’s going to happen, is that now your screen will be so dark that you’ll wind up brightening your photos using your editing software.  THAT is what you want.  That’s the whole point of this exercise.  It’s so that when you edit the photos on your screen, you’re editing knowing that what’s on the screen is what you’re going to get when you print.  So if the picture looks too dark or too contrasty on the screen (which it will if you’ve lowered the brightness a lot), you will then brighten up the photo in editing software to make it look right.  Then when you print it, it will have the correct brightness.  Similarly, if the screen now has people with really orange faces (which is common), you will use your editing software to remove the orange and return your friends and family to their normal skin tones.  Then they will print perfectly.  (FYI, I usually do this color adjustment by adjusting either the White Balance or Color Balance setting, depending on what software I’m using at the time).  If you keep getting prints that are too dark, also make sure that you look at photos on the computer screen when there is a lot of ambient light in the room, either by looking during the day, or with all the lamps in the room turned on.  Many people are night owls like myself, working away at midnight in relative darkness.  On the screen, while editing in a dark room, the photos may look fine.  But if you look at them on the screen during the day or with the lamps on and suddenly you can’t make out the details in the dark areas anymore, then you know you have to brighten the photos some more.  It make take one or two rounds of making test prints, but after a few tries, you will find the settings that are just right.  The key here is achieving consistency.  You always want to make sure you have your monitor at the same brightness, and that you use the same printing lab every time.  Find one that you like, whether it’s Costco, Walgreens, Mpix, or whoever, and get to know how their printers print.  Once you’ve got your system all set up, you will get consistent prints every time.  Also, recalibrate your monitor every once in a while (once a month or so).  Monitors can “drift”, meaning that the color settings can gradually change a little over time, so re-calibrating will bring everything back in line.

OK, so there is actually a lot more to talk about, which I’ll get into now.  What we’ve accomplished so far is getting the screen to match the printer, which is exactly what we want, and is the overall goal.  There are a couple of other things to think about though, before we get into the section with some of the more advanced topics for those that are interested.

Let’s talk about the Internet for a bit, and pictures for the web.  Everything we’ve described here is intended for the purpose of making good PRINTS.  This has nothing to do with how pictures look or should be edited for viewing on the web.  This whole topic of web viewing is one of the areas where opinion varies on how to handle it, and I’ll give you my opinion on the subject, and you can make your own decision.  The “issue”, in a nutshell, is that most people in the world are NOT viewing the Internet on calibrated monitors.  Your average person looking at Flickr or Facebook or whatever photo sharing site is just looking with a normal monitor, just like yours before you calibrated it.  You may see where I’m going with this now…  just like the problem with prints, a similar problem can happen for the web.  If you were to edit your photos on a calibrated monitor ONLY, you will wind up making them very bright and removing the orange so they look great in print, but then when someone looks at that same picture on the web, it will be TOO bright and there will be too LITTLE orange.  So…what to do...  Well here’s what I do.  The reality is that I only print a small percentage of my photos.  I may get 50 keeper photos on a trip, but I probably print maybe 10 of those, and the rest go on my website.  So I do most of my editing on an UN-calibrated monitor, and then turn on the calibration when I edit the 10 photos for printing.  There is usually a simple switch in the calibration software that allows you to turn on the effect or turn it off.  For normal everyday web surfing, I have the calibration turned off.  This allows me to see everyone else’s web photos as they intended – because they edited theirs on a NON-calibrated monitor too.  I’ll also be surfing the web on a screen that is not too dark, which it can be if I were to turn the calibration on.  I’ve had some discussion with other photographers about this, who have suggested that I just leave the calibration on all the time, and they say that if I haven’t calibrated at all, I’m editing my web photos using the exact peculiarities of my particular monitor and no “standard” at all.  While “technically” that is true, I have done an incredible amount of research on this.  I have looked at countless monitors, LCDs, laptops, etc. to see how my pictures look on a variety of uncalibrated monitors.  And I’ve found that most uncalibrated monitors look pretty much identical.  I’ve looked at all of my friends’ monitors, I’ve looked at monitors, LCDs and laptop screens in every store from Best Buy to B&H to the Apple Store, I’ve looked in Internet cafes, in hotels, airport lounges, you name it.  The look is pretty standard.  So for web viewing, I do all my editing on an uncalibrated monitor.  For the few images I’m going to print, I make a second copy of the photos and then I turn on the calibration and edit those separately for print.  This is the system that works for me, and provides the best results for both the web and in print.

Alright, we’ve covered a lot, and for many of you, what I’ve written above may be all you want to or need to know.  What I’ve written above applies to your casual everyday user who uses straightforward editing software like Microsoft Picture Manager or Apple iPhoto or Picasa, etc.  If you’re using one of those, congrats again… you’re ready to get great prints if you follow the steps above.  There are a couple of more advance topics however, and these include printer profiles / ICC profiles, Color Spaces like sRGB, Adobe RGB, and ProPhotoRGB, etc.  If you’re interested in learning what these are all about, read on, but for the everyday casual user, it’s not “necessary” reading.  I just figured I’d cover it since it comes up all the time.  It’s up to you…  ***By the way, if you’re already calibrating your monitor but are still having significant color differences from your screen to your prints, then it’s probably worth reading the info below because it may be related to your problems.***


Before I begin the next section, I’d like to preface with a disclaimer.  This next section deals with personal preferences and opinions.  Not everyone out there will agree with what I’m writing.  In my other articles, we’re dealing primarily with facts.  For example, ISO 100 pictures are of better quality than ISO 1600 pictures.  That’s a fact.  So my suggestion to shoot at ISO 100 is based in fact.  On the other hand, the info below is largely opinion.  These topics are hotly debated among professionals.  I can only give you my opinion, take from it what you will and then make your own decisions based on what I’ve written here.

The next topic we’ll cover is “Color Spaces”.  These are spaces like sRGB, Adobe RGB, and ProPhoto RGB. 

What is a Color Space?  A color space is just a description of the number of colors and types of colors that can be produced.  For example, let’s use sRGB as a starting point.  Let’s say sRGB describes all the colors than can be produced if I gave you 10 crayons.  You can create a picture with the 10 colors of the crayons, plus every conceivable color possible from combining and blending those 10 crayons.  With all the different combinations, you could create millions of colors.  FYI, sRGB is the standard for just about everything, from viewing on your monitor, to printing, to photos on the web.  I suggest you use sRGB for everything you do.  Moving on… Adobe RGB is a different color space.  It’s as if I gave you 12 crayons instead of 10.  Yes, “technically” there are a few more colors than can be produced.  But these would be in addition to the MILLIONS of colors you’re already getting with sRGB.  Plus, most monitors cannot even display Adobe RGB – you’d have to spend literally thousands of dollars to buy a special monitor to see these extra colors.  And even if you did buy a monitor that displayed Adobe RGB in your house, those colors are not used anywhere else!  The Internet is only sRGB.  You must convert photos that are in Adobe RGB format to sRGB if you want to put them on the web, Flickr, Facebook, etc.  Oh, and most PRINTERS only print sRGB, so you have to convert your Adobe RGB files to sRGB to print them too.  So why would anyone use Adobe RGB?  Well, in my opinion, you wouldn’t.  With all the converting that is going on, and the potential for problems, it’s just not worth it.  Just to give you the other side of the coin, some say that they like to use Adobe RGB because they feel that during the editing process, they are using the full range of colors that the camera captured.  So they set their camera to record in Adobe RGB, they output their RAW files in Adobe RGB, and they edit in Photoshop using Adobe RGB.  During this workflow, they are theoretically editing a picture which has more colors, which they feel helps with how the final product looks.  But in the end, as mentioned, all those extra colors get discarded when the photo is converted to sRGB anyway, as is necessary for it to be printed, viewed on the web, etc.  For me personally, that just seems like a lot of extra work with not a lot of extra benefit.  ***NOTE:  Using incorrect or mismatched color spaces is one of the primary reasons people get prints that do not match the monitor.***  Check to ensure that you camera is set on sRGB, your RAW file converter (if you use one) is set to sRGB, and that your photo editing software is using the sRGB color space.  FYI, ProPhoto RGB is yet another color space, and has even more colors than Adobe RGB.  Of course, it too would need to be converted to sRGB to do anything useful with it.  Only very specialized applications would require ProPhoto RGB.  To summarize, I recommend you shoot, edit, print, and view files on the web in only sRGB 100% of the time.

Alright, we’re on the home stretch now.  Time to cover the final topic.  This one is probably the most complicated, and is also the topic that is most debated among photographers when it comes to color management.  It’s the concept of ICC profiles.  Warning: This section is extremely technical.  I don’t normally get this technical in my articles, but if even one person can sort out their color-matching problems by reading this, then it’s worth it.

What is an ICC profile?  It’s a file that describes the characteristics of a particular device, like a printer.  You use it so that your computer can “learn more detail” about a particular device, and can (optionally) use that information to help with color matching.  Before we go any further, I'll mention that I don’t recommend using ICC profiles for normal everyday photography work.  That’s not to say that I personally haven’t used profiles at all, because I have, but only in specific unique circumstances.

So what is it exactly, and how is it used?  Think of it this way: an ICC profile describes the characteristics of a device in detail… for example, an ICC profile for Epson printer XYZ might say “I’m printer XYZ and my blue ink is a little more blue than most printers.”  (I’m oversimplifying, but you get the picture).  An ICC profile for a Kodak printer might say “I’m Kodak printer model 123 and my red ink has a slightly pink tone to it.”  So, what you can “optionally” do in software, is something called “softproofing”.  If you’re using Photoshop or another color-managed application, you can do softproofing.  FYI, a color managed application is an application that supports reading and using these types of profiles, among other things.   Softproofing is a technique that can help with color matching.  First, you download the ICC profile for the printer you’re going to be printing to.  It’s just a small file.  Then, essentially what you do is tell Photoshop that you would like to softproof using the Epson ICC profile for printer model XYZ.  Photoshop reads the information in that file and adjust the colors on your screen to more closely match that particular printer.  So in the example above, if you had blue in your photo, Photoshop might display that photo with “extra” blue to match the Epson’s ink.  Many people use these ICC profiles and do softproofing.  I generally do not, except on occasion.  For me personally, it’s another one of those areas where the time spent is not worth the benefit.  I have a pro lab that I use, I know exactly how their printers print, I have no need to start softproofing and using these profiles which only add to the complexity of what I’m trying to do.  It’s up to you if you want to try to use them, but I suggest against it if you want to keep your system as straightforward as possible.

There is one exception to this.  There is a separate and special type of a printer, pretty much a “printing press”, that is used for high-volume printing for things like brochures and magazines.  These printers use a completely different type of technology to print, called CMYK (which stands for Cyan, Magenta, Yellow, and Key (a.k.a. black)).  This printing method is so different than that of “normal” everyday printers, that the colors they produce can be drastically different from your average printer.  If you’re printing brochures, business cards, or preparing photos for magazines that use CMYK printing, then I can suggest you might want to look into softproofing with an ICC profile for that CMYK printer.  This way, you’ll have a better idea of what you’re photo will look like when printing using that method.  The process will also likely involve you actually converting the photo itself to CMYK, but that’s a whole separate process that we don’t need to get into here…

Now that you understand what an ICC profile is and how it might be used, we can cover the very last piece, and that is the concept of “embedding” profiles.  Yes, this is another area that is hotly debated.  And yes, once again, I feel this is an area that adds many layers to the complexity of what you’re trying to accomplish, and is not necessary for everyday use.  Embedding a profile in your photo means that you are including additional details alongside the photo that can be read by a color-managed application.  Remember, a color managed application is an application that is specifically designed to look for and read these profiles.  The goal of embedding a profile is so that if you’re working on your system under a specific profile, and you embed the profile with the photo when you save it, you can send the photo to someone else who also has a color-managed application, and their application will read the profile and adjust the colors so that they see on their screen what you see on your screen.  That’s essentially what it’s trying to accomplish.  (It can be used for printing as well.)  Here’s the problem.  Most people aren’t using color managed applications.  Most web browsers are not color managed.  Internet Explorer completely ignores the ICC profile.  So, the problem is that you may be viewing your photo in Photoshop using an ICC profile, you get it to look great, but when you post it on the web or send it to a friend, or PRINT it, it looks terrible.  Why?  Because you were viewing the photo using the profile and nobody else is.  It’s like our example at the very beginning with the friend who is applying her make-up in the gas station lighting.  She’s applying her make-up under the wrong light.  If you use ICC profiles and then post to the web, you’re essentially doing the same thing.  You’re editing your photo in one type of light, but giving it to people under a different type of light.  Below is a web page that is a fantastic example of this – I’m so glad this person put this together.  Click on the link below and look in the right-hand column a little ways down.  You’ll see a color chart.

http://www.gballard.net/psd/go_live_page_profile/embeddedJPEGprofiles.html

If you’re using Internet Explorer you’ll notice that the names of the colors in the color chart do not match the actual colors in the associated box.  For example, the upper left box shows the word “Red”, yet the box itself is blue.  Clearly this is wrong.  Well, this picture was produced using an ICC profile that is embedded in the image.  On the person’s screen that created this picture, the boxes were correct!  The upper left box was actually red on THEIR screen, because Photoshop was using the appropriate profile and correcting the colors.  However, Internet Explorer is not a color managed application.  Even though the ICC profile is embedded in the image, Internet Explorer doesn’t care.  It ignores the profile and just displays the image.  Not good.  Now, if you were to open this image in Photoshop, or open this web page in Apple’s Safari web browser (which IS color managed), then the photo would look correct.  But how does that help YOU?  It doesn’t, because most people are not using color managed applications.  Most everyday printing labs also ignore the profiles.  So unless there is a really specific reason you need to do this, I suggest avoiding embedding ICC profiles.  I also suggest turning off ICC profiles in Photoshop or your photo editing software altogether.  Why?  Because you may get inconsistencies across your system.  As an oversimplified example, you may see a photo while browsing the web with Internet Explorer and decide to download it.  Perhaps it has an ICC profile embedded.  Well when you open it in Photoshop, if you have ICC profiles activated, the photo will look completely different when you open it than it did in Internet Explorer.  You may no have any idea why it looks one way on the web and another way in Photoshop.  This is similar to the link above.  If you were to download that image to your hard drive and open it in Photoshop with ICC profiles activated, you’ll see something completely different than you would looking at it in Internet Explorer.  To me, this level of confusion and complication is just not necessary.  It can also lead to mismatched colors in your prints.  If you’re editing in Photoshop under a particular ICC profile, and you don’t even realize it, and then you send it to your printing lab and they ignore the ICC profile, your print will come back looking nothing like your screen.  Again, use the example in the link above.  In Photoshop, that upper left box in the color chart looks red.  Send that photo to Walgreens and that box will come back blue.  Now you see why it’s so easy to get mismatched prints!

We’ve covered a lot here and I hope this has shed some light on this very complicated topic.  With an understanding of these concepts, you may be well on your way to getting prints that match your screen.

Using Live View on your D-SLR – Tips and Tricks

Sedona, Arizona

Sedona, Arizona

Live View can be found on just about all new D-SLRs introduced lately, and has become an incredible tool to improve your photography. When Live View originally started appearing on D-SLRs, many photographers dismissed it as a gimmick to appease those upgrading from point-and-shoots. As the technology has gotten better and new features have been introduced, more and more people are realizing what an invaluable tool it can be. This article will discuss some of the uses, tips, and tricks of Live View on your D-SLR.

First, let’s cover two of the more “obvious” uses of Live View. The first is when you’re taking pictures and the camera is in a location where it’s difficult to look through the viewfinder, such as very low to the ground. For dramatic low-angle shots, you used to have to literally lie on the ground to look through the viewfinder to frame your subject. Similarly, shots taken with the camera held high over your head for a bird’s-eye perspective were taken without looking through the viewfinder at all, and hoping to catch the shot you needed. Today, this is a thing of the past and lying in the sand on a beach is no longer a necessity to get low-angle shots. Simply switch to Live View and frame the subject using the LCD – today’s Live View screens can be viewed from almost any angle. Use this technique to get shots that otherwise might not be possible.

Live View is also great when you’re waiting for that “decisive moment”, for those times when you’re exercising your inner Henri Cartier-Bresson. If you’re taking a street scene and waiting for a random person to walk right into that “perfect spot” to make the shot, you can mount the camera on a tripod, have a shutter-release remote control in hand, and wait comfortably. When someone walks by, you can casually glance at the LCD and take the shot with the remote. In the past, you’d have to rush your eye back-and-forth to the viewfinder each time someone walked by, or worse, you’d have to keep your eye glued to the viewfinder for long periods of time. The same technique is useful for wildlife – frame the scene, and shoot when the wildlife is in the perfect position.

Now let’s talk about some of the less “obvious” uses for Live View – the uses that really make it an amazing tool.

Live View is great for focusing, and is one of the best things that’s happened to focusing in years. Whether you use autofocus or manual focus, you absolutely should be using Live View in tough-to-focus scenes. Even with the best, brightest viewfinders, it can still be difficult to focus on certain subjects, especially subjects that are far away or small. With autofocus, the best you can do is hope that the camera has focused correctly, and try to confirm its accuracy after-the-fact using the LCD to review the picture. This is still a hit or miss method. The better way is to use Live View. Using Live View, you have a much larger image to study for focus, making it much more accurate. Even better is that many Live View systems allow you to magnify the live image by up to 10x magnification! This is absolutely amazing. You can use Live View with 10x magnification to tweak the focus and ensure that a distant street sign is completely crisp and clearly in focus. This would have been virtually impossible before Live View.

Macro shooters have rejoiced as well. When you’re working with razor-thin depth of field in macro work, where even a millimeter’s mistake in focus can mean ruining the shot, Live View can be incredibly helpful. Mount your camera on a tripod, frame the shot, and activate the magnification. You can use your camera’s joystick or directional buttons to maneuver the magnified portion of the image over the area you want to check focus. Ultra-precise focusing is now possible like never before.

Another advantage is that Live View provides a 100% view of the scene, whereas many viewfinders provide slightly less coverage. If you’ve ever taken a photo and gotten home to find a tree branch, garbage can, or some other random object at the edge of the frame that you didn’t see when you took the picture, this is a result of a less-than-100% viewfinder. Those objects were there all along – you just couldn’t see them through the viewfinder. Live View provides 100% coverage of the scene, so what you see is what you get.

A great feature of many Live View screens is “exposure simulation”. This can be invaluable for quickly determining the correct exposure, especially in low light. Exposure simulation takes into account the shutter speed, aperture, and ISO you’ve selected and adjusts the image on the LCD accordingly. For the most part, the image on the LCD will match the exposure that will be captured in the final image. I find this incredibly useful in low light situations. I can choose an aperture, say F5.6, and a shutter speed of 5 seconds, and immediately see how bright the final image will appear before I even take the shot. Amazing. I can then adjust the shutter speed to get the exact exposure I’m looking for. I use this all the time.

Live View systems often provide the option of overlaying a grid on top of the image. This can be a fantastic tool for ensuring you have level horizons and straight lines. I have my grid turned on all the time and never turn it off. Many cameras allow you to fine tune the grid to have just a couple of lines, or a very fine grid – choose which works best for you. In architectural photography, this is a great tool to ensure that your verticals are vertical and that you don’t have the camera tilted up or down creating the “pyramid” effect with tall buildings. For me, the grid is one of the tools I use most often, as it’s very important to keep horizons straight and verticals parallel.

You can also use the Live View grid to assist with placing your subject using the Rule of Thirds. Many Live View systems provide a grid that looks just like a Rule of Thirds grid. You can use this to line up subjects on or near one of the grid lines, or at the intersection of two grid lines, assisting with composition.

One of the less obvious, but most useful benefits of Live View is that is removes the need to use mirror lock-up. In most cameras with Live View, when you activate it, the mirror is raised (and stays raised) so that the image coming through the lens is projected directly onto the sensor for viewing. This is great and results in sharp shots because it is not necessary to use mirror lock-up, which was the only method to reduce mirror vibrations before. (For those not familiar with mirror-lock up, it is a setting you activate in the camera that raises the mirror a few seconds before the shot is taken. This results in sharper shots because otherwise the movement of the mirror causes vibrations that can result in blur. If you raise the mirror a few seconds before taking the shot, the camera has a chance to stabilize and stop vibrating before the actual shot is taken.) With Live View this procedure is not necessary because the mirror is already raised the entire time. I find this especially useful for HDR images. I can take three bracketed images in very rapid succession using Live View, and the mirror is raised on all the shots. This is not possible using mirror lock-up.

Finally, Live View can be useful when used with your camera’s depth of field preview button. When depth of field is critical, many photographers use the depth of field preview to determine the effect of their selected aperture on depth of field. This can be difficult to see in the viewfinder depending on the subject and the lighting. Because Live View is “through the lens” technology, the effect of the depth of field button is visible on the large LCD and can be more easily seen.

I hope this article has shed some light on many of the benefits of using Live View in your photography. From assisting with focusing, to determining the proper exposure, to straightening horizons and increasing the sharpness of your shots, it’s an incredibly useful tool.

Top Ten Ways to Improve Your Photography

Tropical and Coastal Stock Photography - Images by Paul Timpa

I’ve written several detailed articles on specific photography topics, but I thought it might be helpful to compile a “Top 10” list of ways to help you take your photography to the next level. This will help tie many of the concepts together and serve as a sort of “quick reference guide”. Feel free to print this out, fold it up, and stuff it in your pocket or camera bag for next time you’re out shooting. If you incorporate even a few of these techniques, you’ll come back with some amazing travel or landscape photos. If you were able to take pin-sharp shots every time, that were perfectly exposed, full of drama, with vibrant colors, and engaging composition, that would be a good thing! These tips will help get you there.

Note: This article is mainly for those using D-SLRs, but some of the tips apply to compact cameras as well. D-SLRs are very powerful cameras. Because of the large physical size of their lenses and sensors (“digital film”), they’re capable of taking photographs that a compact camera cannot take. Add to that the full manual control over the exposure settings, and you can take extremely creative images.

So, let’s get right into it. Try to use some of the items below on your next shoot, and I think you’ll see a tremendous improvement in your pictures.

1) Learn to use “Manual” or “M” mode on your camera, instead of Program Mode (P), Aperture Priority (Av), or Shutter Priority (Tv). It may seem complicated, but it's really easy. In fact, I personally find manual mode to be EASIER to use than the automatic modes! This is because I'm not always wondering what the camera is up to and trying to override the decisions it makes in automatic. Here's an analogy I like to use: Which is easier? --> driving a car where you control both the steering and the speed, or driving a car where you control the steering but a friend controls the speed, and if your friend doesn't get the speed right, you have to start telling him how to correct it, hoping he gets it right. For me, it's much easier just to control both. Trust me, with just a tiny bit of practice, you'll be very comfortable using manual mode, and may even like it better than the automatic modes too.

There are two main reasons for using manual mode. Firstly, it forces you to choose a specific shutter speed and aperture. Both items will need to be manually chosen by you, which is a good thing, because you then have to think about what you’re trying to achieve creatively and stylistically with those choices. Using any of the other modes mentioned above causes the camera to choose at least one of those two items (shutter speed or aperture) if not both. Because background blur / depth of field and the representation of movement in a photo are directly controlled by the aperture and shutter speed chosen, it’s critical to select exactly what they are so you get the effect you’re looking for. The second reason to use manual mode is because on any other mode, the camera is choosing the exposure for you, meaning how dark or bright the photo is. The camera uses a technique where it tries to “guess” the correct exposure, but it’s just a guess. Sometimes it’s correct, and sometimes it’s not. The only way to ensure a correct exposure is to set it yourself. For more detail on how the camera makes its guess at the exposure and a great example of when / why to use manual mode, feel free to see this separate article I wrote on the topic:

http://www.timpaphotography.com/blog/2009/08/how-to-take-sunset-portraits-indoor-portraits-about-your-cameras-light-meter/

 
2) Incorporate “Long Exposures” into your photography. One of the greatest things about photography is its ability to convey motion in a still image, and one of the most creative ways to show this motion is through the use of long exposures (using a long shutter speed). From flowing water, to car trails and star trails, to just people walking, long exposures can create magic in your photography.


[The photo above of Wall Street and the New York Stock Exchange was taken with a long shutter speed on a tripod to blur the people walking]

You’ll need a tripod or something steady to rest the camera on for this technique, because it’s not possible to physically hold the camera still for the duration of the long exposures. Moving the camera would result in blurry photos. Important: You should also use the 10-second self timer to take the shot, as touching the camera to press the shutter button will shake it enough to cause a blurry shot. Better yet, you can buy an inexpensive remote control to trigger the shutter, which allows you more control over when the shutter is clicked. To use this long exposure technique, set the camera up on a tripod or steady object, and choose a long exposure like 2 seconds, 5 seconds, or even 30 seconds. This shutter speed will result in a very bright shot, so set the aperture to something small (a big number) like F16 or F18, which will darken the picture and bring it back to normal brightness. If the photo is still too bright even with the smallest aperture, you can use a Neutral Density filter, which acts like “sunglasses” for your lens, and darkens the picture. Try this technique on water, cars at night, busy streets, etc. and you’ll see some amazing images. A great time to experiment with long exposures is at night, where you don’t have to concern yourself with the pictures coming out too bright. Some of the most stunningly beautiful photography is taken at night, and almost all requires the use of long exposures. At night, set your camera on a tripod or something steady, set your aperture to F5.6 and your shutter speed to around 5 seconds, and make sure to use the self-timer so that you don’t physically have to touch the shutter button. Experiment with the shutter speed to get the correct brightness. You’ll be amazed at the images you can produce with this simple technique.


[The photo above of the Brooklyn Bridge at Night, NYC, was taken with a long exposure] 

 
3) Use wide apertures. A wide aperture is what creates that beautiful background blur and makes your subject “pop”. There is just something special about a photo taken with a really wide aperture that makes it stand out. Whenever you see a portrait and the person is pin sharp, but the background is just a creamy wash of color, it just looks “professional”. This is also one of the things that a compact camera simply cannot do, because it’s a physical limitation of the size of compact cameras. On a D-SLR it’s possible to get beautiful background blur when you use a wide aperture. To further increase the amount of blur, use a longer focal length (zoom in) because longer focal lengths provide more background blur than wide-angle focal lengths. Standing close to your subject also increases the effect. The next time you’re out, set your camera to an aperture of F4 or wider (smaller number like F2.8 for F1.8), zoom all the way in, and try taking some creative portraits or landscapes.


[The photo above of a Pina Colada on a Caribbean beach was taken with a wide aperture to blur the background]
 

4) Keep horizons level and verticals straight. This one is easy, but it can make such a huge difference in the perception of your pictures. You could take the most amazing landscape photo, perfectly in focus with a great exposure, but if the horizon is crooked and slanted, the photo will look amateur. Always do your best to make sure the horizon is level when you take a shot. If it’s not, it’s a relatively easy correction in most editing software, and it takes less than 10 seconds to fix. It may sound silly, but it makes a huge difference. (Of course if you’re intentionally slanting the horizon for some kind of creative effect, that’s something different). As for “verticals”, that’s something that’s a little more difficult to control. When I say verticals, I’m just referring to any perfectly vertical lines in a photo like the sides of buildings, or walls, or lampposts, or anything that runs straight up and down. You get slanted verticals when you point the camera up or down, versus keeping it pointed straight ahead. This is why it’s so common in photos of buildings and architecture… you tilt the camera upward to include the top of the building in the photo and this causes the sides of the building to tilt inward. So how do you fix it? There are a couple of ways. Firstly, try not to tilt the camera. If you don’t think you’ll be printing the picture at a large size, then you can keep the camera level and zoom out wide with your lens to include the top of the building. Then you can just crop out the foreground later which will have the “effect of zooming back in”, except the final picture will have nice straight verticals. If the widest focal length still doesn’t capture the top of the building, you can try to see if you can take the photo from a higher spot like a nearby stairway. This way you might be able to get the top without tilting the camera upward. If none of those works, you can correct it in your editing software using the perspective control features. (For some situations, this may be the easiest way). Lastly, if you take a lot of architecture photos, you can invest in a Tilt / Shift lens (a.k.a. perspective control or PC lens), which allows you take photos of tall buildings without tilting the camera (I have one and I use it all the time). Level horizons and straight verticals really add a level of professionalism to your photos.

 
5) Rule of Thirds. The “Rule of Thirds” is a guideline to help with the composition of your photos – that is, where you place objects within the picture. The basic principle of this guideline is that you should avoid putting the subject of your photo directly in the center of the picture. For example, if you’re taking a picture of an ocean scene, rather than putting the horizon directly in the middle of the picture with the top half of the photo consisting of sky and the bottom half consisting of the land/ocean, think about putting the horizon in a different spot. The Rule of Thirds suggests that it’s more visibly pleasing to have main objects in your picture 1/3rd of the way from the top or bottom, or 1/3rd from the left and right, rather than splitting the picture in half. For instance, for the ocean shot, if the waves of the ocean are especially captivating, you can fill the bottom 2/3rds of the frame with the ocean and the top 1/3rd of the frame with the sky. This tells the viewer that the main point of interest is the ocean and its waves. On the other hand, if the sky is very dramatic, you could do the opposite and fill the top 2/3rds of the photo with the sky and clouds, and the bottom 1/3rd with the ocean. For people shots, consider putting the person 1/3rd in from the left or right, rather than right in the middle. For a sunset, rather than placing the sun directly in the middle of the photo, try placing it 1/3rd from the top and 1/3rd from the left. You’ll see that your pictures actually feel more “balanced” that way because the subject is not cutting your photo in half, leaving your eye bouncing around both halves not knowing which is more important.

6) Take sharp shots. It’s so common to capture what could have been a great image, but it’s ruined because it’s blurry. I’ve written an article dedicated to the topic of taking sharp shots, and I’ll include the link below. To summarize, the most important thing to remember is to use a shutter speed that is fast enough to combat the camera shake that causes blurry photos. My rule, which is conservative, is to double the focal length to determine my minimum shutter speed. This is especially true at longer focal lengths. So for instance, for a shot with the lens zoomed to 100mm, the shutter speed has to be at least 1/200th second. For a focal length at 200mm, the shutter has to be at least 1/400th second, and so on. If you do this, you’ll get a lot more “keepers”. If you have a lens with Image Stabilization or Anti-Shake, you have a little more freedom. Even so, I then shoot at a shutter speed equal to the focal length, so for an image-stabilized lens at 150mm, I’d shoot at 1/150th a second or faster. If you’re in a situation where you need a longer shutter speed than the guideline above allows, because the photo is too dark at faster shutter speeds, it’s simple: use a tripod or rest the camera on something steady. Alternatively, for “snapshots” you can try raising the ISO, but for important pictures, I wouldn’t recommend going above ISO 400 or 800 if using a tripod is an option. The other way to help ensure sharp pictures is to make sure the camera is focused properly. I recommend using only the center focus point, because if you use all the focus points, it’s much easier for the camera to accidentally focus on something you didn’t intend. I’d say more otherwise good photos are ruined because of lack of sharpness than any other technical problem. If you concentrate on getting this right, you’ll be well on your way to taking many more great images. More detail on getting sharp photos can be found in my article on this topic:

http://www.timpaphotography.com/blog/2009/03/taking-sharp-photos-avoiding-blurring-pictures/

 
7) Get creative with Flash. It’s all too easy to just use the flash only at night, by setting the camera to program mode and popping the flash to illuminate your subject. This will get you decent-to-mediocre results, but with a just a small bit of effort, you can take your flash pictures to a whole new level of creativity. Here are a few tips.

Firstly, learn to use Flash Exposure Compensation. This simply controls how powerful the light from the flash is, making it brighter or darker as necessary. This is probably the easiest technique to use, and can greatly improve flash results. In your camera’s settings, there will be a setting for Flash Exposure Compensation. You can change the flash exposure, usually in a range from about -2 to +2 stops. When you do this, the camera adjusts the power of the flash accordingly. It can be very useful in many situations. You may have seen or taken photographs where the flash power is just way too bright. This sometimes happens with portraits when you take pictures from close up. Because you’re close to the subject, the flash power is too bright, making faces appear white or washed out. In this case, simply set FEC (Flash Exposure Compensation) to a negative number like -1 or -2, and take the shot again. You’ll see the lower flash output produces a much more natural result. Similarly, if your subject is very far away, you may want to increase the flash output so that it reaches your subject. You can do this by changing the FEC to +1 or +2 or any number that works for you.

Another important time to use flash is during the day when there is bright sunlight. The bright sun can produce harsh shadows on your subject. The shadows are even darker and more pronounced if the sun is behind your subject. In these cases, it can really help to use flash. Pop the flash and set the Flash Exposure Compensation to -1 (so that it provides just a hint of fill-light) and you’ll see how much better your outdoor photos will look. I often use flash outside during the day.

Finally, you can start to use flash along with your camera’s Manual exposure mode, to capture amazing night images and portraits. For example, for a photo of a person in front of a nighttime city skyline, you can follow these steps: turn off the flash and set the exposure manually for the background, in this case the nighttime city skyline. Once you have the city skyline correctly exposed in Manual Mode, pop the flash to illuminate your subject. You will get a perfectly exposed subject as well as a perfectly exposed background. Use Flash Exposure Compensation to tweak the brightness of the flash if necessary.

 
8) Shoot in RAW mode, instead of JPEGs. Shooting your pictures using your camera’s RAW mode, vs. shooting JPEGs, will greatly affect the final look of your pictures for the better. You may have already seen my detailed article on this topic (I’ll put the link below), but to summarize: Shooting in RAW gives you the flexibility to adjust the contrast, saturation, sharpness, and white balance “after” the photo is taken. These elements are absolutely critical to the final look of your photo. When you take a photo using your camera’s JPEG mode, the settings for saturation, sharpness, contrast, and white balance are “burned into” the picture permanently and cannot be changed. The only way to adjust these after the fact is if you tried to manipulate the image in Photoshop or some other editing program, which could severely degrade the quality of your photo. Further, shooting in RAW provides a higher-quality picture because the photo is not “compressed” to make the file size smaller, like it is with JPEGs. If you want to take your photography to the next level, you really should be shooting in RAW. I often get asked about the vibrant colors in my photos – it’s from shooting in RAW. More detail on shooting in RAW can be found in my article on RAW vs. JPEG:

http://www.timpaphotography.com/blog/2009/02/shooting-in-raw-vs-jpeg/

 
9) Use filters. There is still a place for filters in your camera bag, even in the digital age where images can be edited in Photoshop. Photoshop will never be able to blur a waterfall (not realistically, anyway) or remove glare from the ocean. This is where filters come in, and they can make a wonderful impact on your photos. The #1 filter that every photographer should have is the polarizer. It’s easy to use and can have a great impact on your photos. A polarizer reduces reflections, which has a couple of beneficial effects on your photos. For daytime shots, blue skies get deep blue and beautifully saturated, and clouds really pop. For distant objects, a polarizer cuts through the haze. On water, a polarizer reduces reflections on the surface of the water, allowing you to see what’s beneath the surface.


[The photo above of a woman snorkeling in Tahiti was taken with a polarizer to remove reflections from the surface of the ocean]

It also reduces reflections of water droplets on leaves and foliage, increasing saturation. For glass and other reflective objects, reflections are removed allowing you to see through the object. I use it especially in tropical locations with gorgeous turquoise water, to cut the glare, allowing you to see the coral and ocean life below.

Another type of filter is the Neutral Density filter. “ND” filters reduce the amount of light that goes through the lens (much like a pair of sunglasses reduces light getting to your eye), effectively darkening the photo. This allows you to use long shutter speeds during the day or at night, without the picture getting too bright. The long shutter speeds will allow for fantastic motion blur effects, and are necessary to blur moving water and waterfall photos that are taken during the day.


[The photo above of a waterfall in Costa Rica was taken with a Neutral Density filter to allow for a long exposure during bright daylight conditions]

A twist on the ND filter is the Graduated ND filter, which reduces the amount of light going through the lens, but only for a portion of the picture (for example, just the top half). This is useful for sunrises / sunsets or any scene where half the picture is very bright and the other half is darker. You simply place the dark half of the filter over the bright part of the scene to even up the lighting for a perfect exposure. For more info on filters and how to use them, I wrote a more detailed article here:

http://www.timpaphotography.com/blog/2009/07/camera-filters-for-photography/

 
10) Shoot in the right light. This is one of the most important, though “abstract” tips. Truly understanding this principle is possibly the single most fundamental technique that will improve your photography. Shoot in the right light. Think about it – you’re not “really” photographing an object. You’re photographing light. Here’s a very oversimplified example that will illustrate what I’m talking about. Go on a beach and take a picture at 2 o’clock in the afternoon. Return at midnight to the same spot and take the same picture at night. Do they look the same? Of course not. The beach itself is exactly the same, but the “light” is different. Yet you have two wildly, drastically different photographs, even though the location and the subject is identical. It is critical to think about that and understand that as a photographer. Whenever you’re shooting travel or landscape photography, think about the fact that you are shooting the light, and not “just” the object. Decide on the quality of light you want to shoot, that is, how bright, how dark, is it sunlit, moonlit, from what direction, etc. Then go take your photographs when the light is right. You may have heard the term “golden hour” used by photographers. This refers to the light you get outdoors just before/after sunrise and just before/after sunset. This is generally some of the best light to shoot in, because you get beautiful golden sunlight cast on your subject from an angle (which brings out texture), the scene is not too bright so you don’t have harsh shadows, and the sky is deep and saturated with a multitude of colors from golden yellows, reds, and oranges to deep blues and purples. Shooting in the right light can transform an ordinary photo into something special.
