Wildlife photography offers particular challenges in composition, especially for beginners. You not only have to create a compelling composition (which is tough enough in itself), you also face a subject which may or may not want to cooperate. I can't help you much with an uncooperative subject. Rest assured that with practice and experience, you will find that you become much quicker at composing and exposing a photo so that you get the shot before the critical moment passes. There are a couple of simple tips that can make things a little easier. First, practice your photography in places where the animals are used to having people around and are less likely to become jittery at your presence.
This does not have to be a zoo or other enclosure. Most national parks have campgrounds and picnic grounds where the wildlife is used to being around people, and may even come closer looking for food. You have a much better chance of a shot if you can get close without frightening the subject away. Second, try to organise your exposure before you set up the shot.
If the light is fairly constant, it is possible to point your camera in the right general direction and work out the best aperture and shutter speed settings for the photo. Then when you approach the subject, you can concentrate on composition without having to waste time working out your exposure. These simple tips may help to take some of the frustration out of wildlife photography, but what about the composition itself? Many people simply don't know where to start.
If that sounds like you, don't be discouraged. Like I said at the beginning, composition can be tough; even for a photographer with years of experience. Let's start by breaking it down into two categories; close-up and non close-up photos.
In a close-up photo, the subject fills most of the frame. A lot of people get in a tangle over whether to position their subject in the middle or to one side of the composition. In my experience it is quite acceptable to have the subject right in the centre, as long as you allow some head-room so it doesn't appear too cramped within the confines of the composition.
A central position is especially suitable when the subject is looking straight at the camera, but often works just as well if the subject is facing a little to one side or the other. The more space you have around the subject, the more you should consider putting it to one side or the other. In this you should be guided by the way the animal is facing. If it is looking to one side, position it a little towards the other side so it is looking toward the centre of the frame. So, if your wildlife subject is looking right, position it a little to the left. Not too far; you don't want half of your photo to feature nothing but empty space.
In a non close-up, where the photo shows a lot more space around the animal, it becomes more critical that you use that space effectively. In situations where the animal is featured with a lot of background, it may be better to think of the picture as a landscape photograph, and compose it accordingly. Some of the tried-and-true techniques like the Rule Of Thirds (google it if you are not familiar with it) are a good way to help you position your subject within the overall frame of the picture.
For a landscape style photo, it may look quite unbalanced to position your subject in the centre of the picture. It is usually better to position it to one side or the other, and it is now even more important to have the animal facing toward the centre of the picture. The eyes of an animal subject can have a strong effect on the direction in a composition; we tend to look where they are looking. So if the animal is on the left and looking left, the visual flow of the composition will lead out of the picture, instead of into it.
If the subject is on the left and looking right, the viewer will follow the gaze of the subject into the centre of the picture. Naturally it helps if there is something of interest in the centre or to the right to catch the viewer's attention and add interest to the composition. If the subject is looking into the composition, it makes sense that it is looking at something, not just at empty space. Almost anything will do.
a tree, a beach, an impressive sky; as long as it adds impact to the composition. If there is nothing of interest to work with, you might consider zooming in closer, so there is less emptiness in the composition. These simple guidelines are intended to do nothing more than give you some ideas. Nature is not governed by the rules of composition, and a wildlife photographer must be flexible to get the best result out of each situation. Above all, trust your own judgement, your own sense of visual balance, to create a satisfying composition.
On the other hand, if you are struggling to get started, think back to these guidelines; if you can position your subject well, the rest of the composition will fall into place.
