Manual Mode on Your D-SLR — When and Why to Use It

Thursday, January 7th, 2010


Italy Collection – Images by Paul Timpa

Manual Mode on your D-SLR can really help you take your photography to the next level, allowing for spectacular images and much more creative shots.  It is especially important for:

* Sunsets
* Night Photography
* Waterfalls / Rivers / Streams
* Sports / Action

Many of you who have read my previous articles have heard me mention “Manual Mode” on cameras, and how using it can really help your pictures.  I decided to write an in-depth article on the benefits of using manual mode, and why it is often actually easier to use than the automatic modes like “Aperture Priority (Av)” or “Shutter Priority (Tv)”.  I hope after reading it, you too will give it a try and find that it’s the easiest mode to use and also results in the best photos.

I’ve guest-posted this article on a colleague’s blog, and you can read the full text of my article here:

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

Thursday, November 12th, 2009
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.

As always, if you have any questions, please let me know.

Paul

Photography Tips for Compact Cameras and Point-and-Shoots

Wednesday, July 15th, 2009

Just because you may not have an expensive D-SLR camera, doesn’t mean you can’t take incredible photos.  Compact point-and-shoot cameras are capable of capturing extraordinary images, and their quality gets better and better with each new camera.  I’m taking a different approach for this latest article, and writing a tutorial aimed at those who shoot primarily with a compact camera. Using some of the tips I present below, you’ll be able to take photos with much more impact.

Compact cameras have some distinct advantages over D-SLRs in a few respects.  Firstly and most obvious, is their size.  Because of their size, it’s easy to take one wherever you go, and you’ll always have the opportunity to take a great photo should something amazing unfold in front of you. Their zoom lenses generally cover a wide range so you can take wide-angle shots of landscapes and buildings, and telephoto shots of distant subjects, sports, etc.  Because the sensor and lenses are physically smaller than D-SLRs, you’ll often be able to get everything in sharp focus, from objects right in front of you to distant mountains (this is not always easy to do with a D-SLR).  Compact cameras almost always have a built-in flash for when you need it.  Most compacts are also great for close-up macro work of flowers and other small subjects.  All of these factors combine to make a compact a great camera to have, even for those who already own D-SLRs.

So what can you do to take your photos from simple “snapshots” to amazing photos worthy of framing on your wall?  Below are a series of tips and techniques to help you get the most from your compact camera.  Some are “technical” ways to operate the camera, while others are tips related to composition and how to “frame up” your subject.  If you combine them all, you’ll be on your way to capturing incredible images.

First, let’s talk a little about focal length.  Focal length just refers to how much or how little you’ve zoomed in or zoomed out.  If you’ve zoomed your camera all the way out, you’re taking wide-angle shots and capturing a wide area of space around you.  This is a short focal length.  You’re probably used to doing this if when you’ve taken a picture of a large group of people, or you’re taking a wide-angle photo of the Grand Canyon or a big expanse of beach.  On the other hand, if you’ve zoomed all the way in, you’re bringing far away objects closer to you, and you’re using a long focal length, a.k.a. telephoto.  You probably use this at a sports event or ballgame to bring players closer to you and make them bigger in the picture.  Many people think of zooming in and out in terms of those two types of situations:  “I need to take a picture of a wide area of space so I’ll zoom out” or “That person is really far away so I’ll zoom in to make them bigger.”  While that does work, there are far more powerful ways to use focal length to your advantage.

Rather than thinking of zooming in and zooming out in just the two types of scenarios described above, it’s useful to understand some additional, more creative concepts related to focal length.


Let’s start off with a straightforward one.  While you may be used to the idea that zooming out wide captures a wider expanse of the scene, you may not always be thinking in terms of the opposite:  when zooming in, you’re taking in a lot *smaller* portion of the scene.  Most of us are used to thinking in terms of zooming in to bring far away objects closer, but just as important, if not more important, is the fact that zooming in reduces the area of the scene that is being captured (in addition of course to making the object seem closer).  You may be asking, so what?  What does this have to do with my photography?  The answer is this: armed with this knowledge, you now have the choice of what background you want for a picture of any given subject.  It can be incredibly helpful for clearing up clutter, simplifying your pictures, and making them better.  Let’s use an example to illustrate.  Let’s say you’re taking a picture of your friend in front of a beautiful mountain, from a scenic overlook on the road.  You stand a few feet from your friend, zoom out nice and wide to make sure you get all of the mountain in the shot, and you take the picture.  You know what else you probably got in the shot besides your friend and the mountain?  …the trash can 15-feet to the left, the telephone pole behind your friend about 20-feet to the right, and who knows what else.  Because you’re using the wide-angle setting, you’re capturing a very wide expanse of the scene… this expanse may include objects that you don’t want in the picture.  Here’s where zooming in and its ability to *reduce* the scene can be helpful.  Instead of taking the shot from a few feet away and zooming out wide, step really far back from your friend and zoom all the way in.  You need to take the picture from farther away, because as you know, zooming in will make your friend bigger in the picture.  You want to counteract that and keep them the same size in the picture by taking a few steps back.  But in the process of zooming in, you are reducing the area to the left and right that is in the picture.  If you’ve zoomed in enough, you will completely eliminate the trash can and the telephone pole from the shot, leaving just your friend and the mountain.  This is one of the most fundamental techniques in photography and one you should master through practice.

In addition to its effect on how much or how little of the scene gets captured, focal length has another important effect, and that is its effect on “perspective”.  Perspective refers to how far away from each other any two objects look in a photograph.  You may be surprised to learn that zooming in and out has a HUGE impact on how far apart objects “appear” in a photograph.  Keep in mind that how they appear in the photo has nothing to do with how far they appear in “real life”!  Let’s use the example we used before with your friend and the mountain.  Let’s say that the mountain is about two miles behind your friend.  Just looking with your eyes (no camera), the mountain will appear, as it should, to be two miles away.  If you zoom your lens to somewhere in the middle of its range and take a picture, when you look at that picture, the mountain will appear to be two miles from your friend.  That’s a “normal” focal length.  However, if you zoom out wide and take the same picture, the optical qualities of the lens will in fact exaggerate that distance greatly.  If you take a picture and look at it, you may be shocked to see that the mountain now “appears” to be five, ten, or even twenty miles away!  Wide angle lenses exaggerate distance.  On the other hand, if you zoom all the way in and take the picture, you will see that the mountain may appear to be directly behind your friend, maybe a few hundred meters or less!  It may appear that your friend is literally standing at the base of the mountain.  You can use focal length to adjust the closeness of the background to exactly how you want it.  Just remember that if you want your friend to be the same size in the picture, you may have to step closer or farther away from them, depending on how far you’ve zoomed in or out.  This perspective effect is why you sometimes see pictures of people with a sunset, and sometimes the sun is a tiny yellow dot in one picture and in another it’s a huge orange ball.  In the picture with the huge sun, the photographer has stepped all the way back and zoomed in as much as they can, making the sun appear much closer.

One of the most important tips I can give for shooting people is also related to perspective… and that is: take photos of people’s faces from far away and zoom in!  Pictures of people taken from farther away with the lens zoomed in are much more flattering than pictures taken up close.  Have you ever seen a picture of a person taken up close with a wide angle lens, or been out with friends and tried to hold the camera in your hand with an outstretched arm, pointed at yourselves?  You’ll notice that your noses look bigger than they really are and your facial features are exaggerated.  This is because the camera is close to you and the wide-angle lens is exaggerating distance… in this case it’s exaggerating the distance from the tip of your nose to the rest of your face!  It will look larger than it really is.  If you stand back and zoom in, you reduce this effect and the face will have normal proportions.  Did you ever wonder why Sport Illustrated photographers are standing half-way across the beach shooting the models with a huge telephoto lens?  Perspective is part of the reason…

The next tip is a brief one, but it can be invaluable for architecture photography and photos of buildings or other tall objects.  (You may want to use software to crop the picture after using this technique, but most people are familiar with basic cropping.)  The tip is this:  whenever possible, when taking photos of tall subjects like buildings, do not tilt the camera upward to make sure you get the “top” – instead, keep the camera level (not pointed upward) and zoom out as wide as you can (in order to get the top of the building) and take the picture.  The reason for this is because tilting the camera upwards causes the walls of buildings and vertical objects to point inward like a pyramid.  The building may appear to be leaning back or falling over. 

Walls are pointing inward because camera is tilted upwards

If you keep the camera level, this won’t happen.

You may however, have a large expanse of ground in front of you, which you can then simply crop out later.  With high-mexapixel cameras these days, cropping should not affect picture quality unless you’re making massive prints.

Now let’s talk about flash.  Built-in flash can come in very handy when you need a little bit of extra light, but flash is often not used to its full potential, and sometimes it’s used when it shouldn’t be.

First I’ll make one important comment.  The light from the flash on your camera probably only “realistically” reaches about ten feet or so in front of you.  After that, the flash has no effect.  If you’re taking pictures of something that is more than ten feet in front of you, turn the flash off (you may need to refer to your camera’s instruction manual to determine how to turn it off, as many times it comes on automatically).  Sometimes I go to a baseball game and a famous pitcher will be put into the game and everyone in the stadium is taking pictures of the pitcher from hundreds of feet away, but all I see are flashes going off.  Every one of those flashes is illuminating the back of the head of the person in front of the photographer, and not much else.  I can assure you that flash is not reaching the pitcher’s mound.  Worse yet, with the flash on, the camera is making decisions as to how to expose the photo.  It “assumes” that the light from the flash is reaching the subject, and thus it darkens the photo in anticipation of it being lit by the flash – however the flash never reaches the subject, and now you’re left with a dark photo (or a perfectly exposed picture of the back of someone’s head).  In these situations, it’s best to turn the flash off.

On the other hand, one of the best places to use flash is actually in bright sunlight.  When the bright sun is overhead, it can cast shadows under the eyes and generally result in an unflattering picture.  Turn your flash on and the flash will brighten up the shadows resulting in a much better picture in broad daylight (refer to the manual to learn how to turn on what is often called “Fill Flash”).  Similarly, if you’re taking a picture of a person in front of a bright background, like a sunset, turn on the flash.  Without the flash, it is likely you’ll just get a silhouette.  That may be the effect you’re going for, and if so, leave the flash off.  If you want to see the person’s face, turn the flash on. 

Flash is also useful for close-up shots of flowers.  Not only will it brighten them up and help with shadows, but the flash will help “freeze” any movement of the flower caused by wind.

Whenever possible, I’d recommend taking two shots – one with the flash on and one with the flash off – in any situation where the flash might be helpful.  You never know which one you’ll like best, so it’s best to have both.

Now let’s cover some technical tips about night photography.  In this case, I’m referring to nighttime shots of city skylines, buildings, landscapes, etc. (and not necessarily pictures of people).  Night photography can produce some truly spectacular images.  It is however one of the most “technically” challenging types of photography.  It’s all too easy to wind up with a blurry shot or poorly lit shot.  Here are some tips:

Most importantly, it’s virtually impossible to take a sharp night shot while holding the camera in your hand.  You’ll need to find a place to put the camera down.  If you don’t have a tripod, just look for a bench, a railing, a tree branch, a soda bottle, anything to prop the camera up on.  Even if the camera isn’t pointing “exactly” where you want it, you can always crop out parts of the picture later… resting it on something will always result in a better shot than you trying to hold the camera.  The second piece to this tip is that you *must* use the camera’s self-timer to take the picture.  All too I often I see people going out of their way to prop the camera up on something to hold it steady, only to use their finger to press the shutter button.  Using your finger to press the shutter button will completely blur the shot and negate and beneficial effect of propping the camera up.  So just prop the camera up pointed in the right direction, set the 10-second self-timer, and let the camera do its thing.  Also ensure that the flash is off.  Going back to our previous discussion about flash – we know it only reaches about 10 feet, and having it on negatively affects the brightness of the picture, so turn it off.  If your camera has any kind of “Night Scene” mode (and most do), then definitely feel free to use it.  Most “Night Scenes” modes instruct the camera to leave the shutter open for a longer period of time than it normally would – the longer the shutter is open, the more light gets in, so you get a better, brighter picture.  Just make sure the night mode doesn’t automatically turn on your flash – if it does, make sure you can turn it off.

For situations where you’re handholding the camera in dim lighting, for example when taking a picture of someone blowing out candles at a birthday party, you may wish to take the picture without flash to preserve the “ambience” of the scene.  You may also be too far away for the flash to reach, for example taking a picture at a concert or school play.  Any time you’re handholding the camera in dim lighting without flash, it’s possible you may get a blurry shot due to camera shake.  The camera needs to keep the shutter open longer to let more light in so the picture is bright enough, but the longer the shutter is open, the more chance there is of the camera recording any slight movement (of either the camera OR the person you’re taking a picture of).  You can help fix this by manually adjusting the ISO if your camera allows you to (many do).  ISO is used to magnify the amount of light entering the camera — the more light the camera gets, the less time the shutter needs to be open, resulting in less blur and sharper pictures.  ISO is rated in numbers, usually around 100 at the lowest, and going up to around ISO 800 or so on compact cameras.  The higher the ISO number, the more light gets in the camera and the faster the shutter speed.  The tradeoff with ISO is that picture quality is best at low ISOs, and deteriorates at higher ISOs, so you only want to use the highest ISO that eliminates the blur, but no higher.  Personally I recommend not going above ISO 400 on compact cameras.  So how do you use it?  If you find yourself in a situation like the ones mentioned above, where you want to take a picture in dim lighting without flash, but the picture comes out blurry, then simply raise the ISO number in your camera.  You may need to consult your camera’s manual on how to do it.  Many cameras just have a button or menu item that says ISO.  Start at ISO 100 to see how sharp the shot is, and if there is any blur.  If it’s a little blurry, then raise to 200 and take a test shot.  If it’s sharp now, then leave it at 200 and you’re ready to go.  If the shot is still blurry, then raise to 400 and try again, and so on.  You’ll see that raising the ISO can really help in getting sharp shots in dim lighting.  Keep in mind that the picture quality will not be as good as if you took the shot at ISO 100, but in many cases, a little less picture quality is worth it to get a sharp shot, because a blurry shot may be unusable entirely!

The final “technical” tip is about “Exposure Compensation”.  If your camera has exposure compensation, and many do, it’s worthwhile to learn how to use it.  Exposure compensation simply lets you adjust the brightness of the picture to your liking.  Under normal circumstances, when you press the shutter, your camera looks at the scene, performs some calculations, and determines how bright the shot should be.  In many cases, the brightness level it chooses is pretty good.  Sometimes however, the camera can be thrown off in certain situations.  For instance, if you’re taking a picture on a ski mountain, the camera can be “fooled” by all the bright snow.  The camera says “wow this is really bright out here” and so it darkens the picture thinking that’s what you want.  You may wind up with snow that is more of a “light gray” than white.  In this case, you may want to use exposure compensation.  You might see it as a +/- where you move the arrow toward the “+” to make the picture brighter and the “–“ to make it darker.  Take a look in your camera’s manual to learn how to set it for your particular camera.

OK, let’s move on from the technical details and cover some pointers related to composition.  Composing the picture just refers to deciding what to include or exclude in the photo and where to position the subjects in the frame, the angle of the shot, how much you’re zoomed in, etc.

The most useful compositional tip is probably “The Rule of Thirds”.  It’s not really a “rule”, but rather a guideline to keep in mind when you’re taking pictures.  The Rule of Thirds is designed to help you determine where to place your subjects in the frame.  It’s easy.  When framing your picture, mentally draw a tic-tac-toe board over the scene – so there will be two vertical lines and two horizontal lines dividing the picture into thirds.  When taking a picture, try to place your subject along one of those lines.   (Some cameras even have a feature where you can turn on a Rule of Thirds grid that appears right on the LCD — you can check your manual to see if yours has it).   Notice how the horizon is on the lower horizontal line and the bird is on the left vertical line:

Newport, Rhode Island with Rule of Thirds Grid

What you’ll see is this helps you avoid putting your subject dead center of the picture, which is often the worst place to put the subject.  The subject can be a person, or a sunset, or anything else.  If the subject is small in the frame, like the moon, you can place it where two of the lines intersect, which is even better than just putting it on one of the lines.  The next time you’re taking a picture of a sunset, instead of putting the horizon straight through the middle of the picture, cutting it in half, try putting the horizon one-third from the top or one-third from the bottom and you’ll see how much better it looks.

The next compositional tip is called “Leading Lines”.  Leading Lines refers to using objects in your photo to lead the viewer “into the picture.”  It can be a pathway, railroad tracks, a pattern in waves, etc.  You place the leading line so that it starts in the foreground (the bottom of the picture) and your eye follows it further into the picture.  It’s often best to put leading lines a little bit off to one side and to lead your eye diagonally into the frame, but experiment to see what you like best.

Another simple tip is related to moving objects such as people running or cars moving.  Always allow space for the moving object to “move into”.  For instance, if you’re taking a picture of a car moving from right-to-left, make sure there is room on the left side of the picture for the car to “drive into” (otherwise the photo will look cramped).

Patterns are all around us and can be used to create amazing photos.  No matter where you are or what you’re doing, have a look around and you’ll see patterns, many of which can be great photo opportunities.  The pattern can be anything from a repeating line of sun umbrellas on a beach, to an interesting row of trees, a fascinating pattern that all the windows of a skyscraper make, or something as simple as some cherries in the market.  The key when looking around for patterns is to avoid getting caught up in the “wide expanse” of the scene where it may be harder to recognize patterns, but rather focus in on small areas of what’s around you.  In the photo of the cherries below, it could have been easy to miss it in the hustle and bustle of the market, with the flowers right next to them to the left and the pile of onions to the right, but if you take the time to look, you’ll see patterns everywhere.  When you do, you can either take the photo of the pattern in the larger context of the whole scene, or focus in and create a more “abstract” photo.  Each can produce interesting images.

The final compositional tip is to make use of “Natural Frames”.  A natural frame is something in the scene that you can use to literally “frame” your subject.  It helps draw attention to the subject and adds a lot of impact.  You can use archways, tree branches, anything at all really.  Step forward or back as you need, to place your subject in the natural frame, and take the shot.

With a little practice of the technical and compositional techniques you’ve read here, you’ll find that you can take amazing shots with a compact point and shoot.

Night Photography / Low-light Photography — Tips for Night Photos

Tuesday, April 14th, 2009
Star Trails, Costa Rica

Star Trails, Costa Rica

The allure of the night shot. The sparkling lights of a city skyline, the moonlit seascape, neon signs, and star trails to traffic trails… For some (including myself) the night shot represents the epitome of fascinating, enthralling photography. Looking at these photos in awe, we cannot help but say “wow”.

Of course, one thing separates night photography from many other types. It requires a fairly significant amount of “technical” skill to get good results. It’s much easier to wind up with blurry, incorrectly exposed, or out-of-focus photos at night than it is during the day. So how do we fix that? This brief guide will show you how…

Night shots can be spectacular to look at. A properly executed night image can impress even the most jaded viewer. But one thing ruins probably 90% of night shots out there. Blur. Let’s talk about how to take sharp photos at night…

Because light levels are so low at night, longer shutter speeds are required to allow enough light into the camera to expose the image. You’ll often need shutter speeds that last several seconds. Of course any time you’re using longer shutter speeds, you’re introducing the possibility of blurry images due to camera movement. First and foremost, it’s just not possible to handhold a successful night shot. A tripod or other support must be used, even if it’s just a bench, railing, recycling bin, or tree branch. Yes, “technically” you can up the ISO to get a manageable handholding shutter speed, but I don’t recommend it. High ISOs lead to noisy images (multicolored or white speckles all over the image), loss of sharpness, and loss of detail. If you really want to take a powerful night shot, you should keep the ISO at 100, unless for some unusual reason you need ISO 200. Personally, I wouldn’t recommend going over 100.

OK, so you’ve found a great position to take your shot, and you’ve successfully balanced your camera on the back of a sleeping coyote (he’s very still). Now what? Provided the ISO is set to 100, it’s time to set the exposure…

Firstly, set your camera to full-manual mode where you manually set the aperture and shutter speed individually. Your camera’s meter doesn’t work well at night and will only cause problems and inconsistencies from shot to shot, so don’t concern yourself with it. Once in manual mode, it’s time to determine what to set for shutter speed and aperture. If we know that the longer the shutter is open, the more chance there will be of movement (resulting in blur), then we should do whatever we can to get the shortest shutter speed possible. Since we’ve already established that we’re sticking with ISO 100, that means we need to use the widest aperture that will work for the scene. Using a wide aperture (low number), more light enters the camera and you can use a faster shutter speed. Unless you have objects that are both very close to you and very far from you that all need to be in focus (which I find rarely to be the case in night photography), you can get away with fairly wide apertures such as F5.6. I’d recommend starting with an aperture of F5.6 and a shutter speed of 3 seconds. This usually provides me with a good starting point of evaluating how much light is in the scene and often results in a decent starting exposure. Look at the LCD and see if the image appears too dark or too bright. If it’s too bright, set the shutter speed to 1.5 seconds and try again. If it’s too dark, set to 6 seconds. Experiment with various settings until you arrive at a shutter speed that works for the scene. There are three main reasons why you might want to have a smaller aperture (keeping in mind that you will be lengthening the shutter speed and increasing the chance of blur). (#1) – small apertures create that “star” effect on small bright lights – if you want the stars, you’ll need an aperture of at least F8, and more likely F11 and smaller, (#2) if you have objects that are up close and also far away, and all need to be in focus, then you’ll need a small aperture to increase depth of field, and (#3) for creative purposes, for example if you want a longer shutter speed to increase the effect of traffic trails, to create a silky blur of the ocean, or to allow yourself time to do some “painting with light” (using a flashlight to manually illuminate certain areas of a scene), etc., then you may want to use a smaller aperture.

Let’s talk about focusing for a bit. The reality is, cameras really don’t autofocus all that well in the dark. You’re going to have to rely on some skill here. When you attempt to use autofocus in the dark, generally one of two things happens: either the camera focuses on the wrong object or the camera hunts around in the dark for a few seconds, it can’t find anything to focus on, and it prevents you from taking the shot. Neither one is what you want, especially if a spectacular scene is unfolding in front of you. There are really only two options. Firstly, you can set the lens to manual focus and just use your eye to focus as best you can. If you’re focusing on a far away city skyline or landscape, you can just look at the lens barrel and focus at infinity using the infinity marker on the focus ring. The second option, and the one I use most often, is a hybrid of auto and manual focus. Set the camera to use only the center focus point and turn off the other focus points. On most cameras, the center focus point is the most sensitive to light and works best in the dark. Look through the viewfinder and position the center focus point on where you want to focus. If there is a bright light near where you want to focus, use that. The brighter the object, the more easily the camera will find focus. Press the shutter button half-way to try to autofocus. You may need to give it quite a few tries for it to successfully lock on. If you successfully autofocus, immediately switch the lens to manual focus on the lens barrel. Be careful not to touch the focus ring and change focus as you’re doing this! Now compose the shot as you need to, again being careful not to touch the focus ring. Now you can take your shot without worry of the camera focusing on the wrong object, or worse, hunting in the dark unsuccessfully and never taking a shot at all.

If possible, I also recommend using your camera’s mirror lockup function, if it has it. This text on mirror lockup is taken from my Note on “Taking Sharp Photos”:

If your camera has a “mirror lockup” feature, you can also use this. You may know that when you click the shutter, the mirror flips out of the way so that the light can hit the sensor. The flipping of this mirror can cause the camera to shake, which is especially visible when using long lenses. By setting the mirror lockup, you are flipping up the mirror before the actual picture is taken, preventing camera shake and the resulting blur.

My final note on sharpness, and something that is perhaps one of the most common mistakes in night photography: always remember to use the self-timer or a remote control to fire the shutter. Using your finger to press the shutter will result in blurry shots. The sturdiest tripod, the most accurate focus, will not help at all if you touch the camera when trying to take the shot. I recommend getting a remote control for your camera, so you don’t have to wait 10 seconds every time you take a shot as you would if you use the self-timer, and you have more control over when it fires (for instance, if you’re trying to fire it exactly when there are no people walking in front of the camera). Remote controls are relatively inexpensive and small (easy to carry around). The one for Canon cameras is less than $25 and it’s smaller than your thumb.

A few tips on specific types of night shots:

Moon photography: The most common mistake when photographing the moon is overexposure. The moon is reflecting the sun. It is extremely bright. You must use very fast shutter speeds to avoid overexposing the moon. If you don’t see individual craters and shades of gray (meaning it just looks like a bright white circle), the image is overexposed. Set a faster shutter speed and try again.

Traffic Trails: By nature of having the shutter open for several seconds during night shots, you will almost always get traffic trails when there are roads in the photo. Set the shutter speed to longer or shorter as necessary to adjust the length of the trails (and don’t forget to adjust the aperture to match the shutter speed you’ve chosen).

Star Trails: If you keep the shutter open long enough, you can capture star trails. Star trails result from the rotation of the earth. Objects on the ground remain stationary, but since the earth is rotating relative to the stars, long exposures will show this rotation (see the shot at the top of this post). You’ll generally need exposures of at least a half hour to show trails (though you will see small trails in as little as a few minutes). You can either take a single shot for the entire duration (which may result in a noisy image, but is very easy to take), or you can take a few shorter shots and layer them on the computer. Set your camera to Bulb mode, and using a remote control, open the shutter, wait the appropriate amount of time (just use your watch), and close the shutter with the remote. Make sure to have something on the ground in the shot, to add interest and emphasize the motion.

Taking night shots can be incredibly exciting and result in some spectacular images. Good luck and happy shooting.
