It’s been said that photography is the art of exclusion. It’s as important, in making a compelling photograph, to exclude what we do not want within the frame of our image as it is to include what we want. In fact, when we include what we want without carefully excluding the rest we introduce too much to the image, and we dilute the impact of the elements we were hoping would make the photograph what it is.
Honing this art of exclusion is a significant step forward on the photographic journey, and learning to isolate your subject is an important part of that. Here are a couple of significant ways you can begin to isolate your subject and give it greater power within the frame, undiluted by the noise of elements that do nothing to help you tell the story.
Nikon D800, 600mm, 1/800 @ f/8. ISO 400. This red-crowned crane was among many at the scene, but isolated with a longer lens it creates more impact within the frame than it might have surrounded by its context.
POINT OF VIEW
The first and most obvious way to isolate within the frame is the intentional use of point of view (POV). What appears and does not appear, in front of, around, and behind your subject has everything to do with where you stand and put your camera. Yes, there are plenty of situations in which moving around will do nothing to get rid of background chaos or unwanted elements, but often a simple change of position can successfully move that unwanted element in relation to your subject. A little movement to the left or right, standing on a ladder or lying on your belly, can push those elements from the frame. Just playing with our point of view can improve an image with no other changes. Next time you’re photographing something, take a little extra time to be aware of what is in, and out, of the frame, and try moving—do a complete circle around your subject if you have to—and see if you can’t strengthen your image that way.
OPTICS
Of course there are plenty of times that moving in relation to the subject isn’t preferable. Moving changes the perspective, and with it, the lines. Moving changes what the light is doing and if you’ve got your heart set on a backlit photograph, then moving 180 degrees will change the photograph completely. When that happens, it’s time to explore other options. The first one I try is a change of angle of view. Where a change of POV means a change of position of the photographer relative to her subject, a change of angle of view is all about which lens you choose. A wide-angle lens, as the name implies, has an angle of view that is extremely inclusive—it pulls a lot into the frame. A telephoto, by definition, is a much tighter angle of view. The most obvious move in pursuing a more isolated subject is to use the longer telephoto lens, and that often leads to beautifully simple images, free from extraneous elements. Next time you’re trying to really isolate something, try backing up and using a longer lens. But that’s the next lesson, so I’m getting ahead of myself. It’s also not the only way to use optics to make a subject stand out.

Left: Nikon D800, 16mm, 1/1000 @ f/11, ISO 200. Using a wider lens forced me to push in tighter, making the foreground larger relative to the rest of the elements, isolating it in a way a longer lens would not have done.
Right: Nikon D800, 70mm, 1/80 @ f/9, ISO 500. Panning with this whooper swan in Hokkaido, Japan, allowed me to create both a sense of motion and a sense of isolation against a background that would otherwise have had more visual pull.
A wide-angle lens can also be used to isolate, though it’ll involve both a change of optics (put that wide-angle lens on!) and a change in position (get as close as you dare!). A wide-angle lens pushed in close will still be a wide-angle lens and will still include more elements than a tighter, longer lens. So how can that be used to isolate? Isolating an element is about making it more prominent than others, giving it greater visual mass, and diminishing distractions. When you push a wider lens much closer to your subject, in the right circumstances it does two things simultaneously: it enlarges the subject and diminishes the rest. When a longer lens doesn’t give you the look you’re hoping for, or excludes too much of the context, try going much wider and much closer.
MOTION
Sometimes the use of depth of field doesn’t help. And sometimes it just doesn’t give you the aesthetic you’re looking for. Motion can be a great isolator. When the subject is moving, you can use a slower shutter speed and pan the camera to create a sharp subject against a blurred background. When the subject is stationary but its surroundings are in motion, you can use the reverse technique—keeping the subject sharp while the moving surroundings blur around them. Both techniques require practice and a slow shutter speed. In the case of allowing the surroundings to blur around a sharp subject, you’ll also need a means to stabilize the camera, such as using a tripod. A friend of mine uses her handbag; others use beanbags or parts of buildings. However you do it, the longer shutter speed creates blur of the once distinct and distracting elements and simplifies them, allowing you to isolate—or more clearly point to—your desired subject. If you’re skipping around this book, now would be a good time to review Lessons 7 and 8.
These aren’t the only techniques. You can use a shallow depth of field too, but we’ll talk about that in Lesson 14. Consider too, for example, the role of light and the ability to blow out a background or plunge areas into shadow. However you do it, the most important part of this lesson for some will simply be the awareness that intentionally isolated elements can dramatically strengthen a photograph, giving the main subject greater visual mass and allowing other elements to remain outside the frame, gain reduced visual mass, or fade into blur.
YOUR ASSIGNMENT
Look at a few of the images you love best from other photographers, and for each image ask yourself one question: What role does isolation play in this image? You might also ask yourself what choices the photographer made to simplify this image and make it as strong as it is. Are there extraneous elements that distract? Isolation is all about simplifying an image of unnecessary elements so the most important elements have the best shot at pulling your eye, your attention, and your emotions.
