- it usually means that you don't miss the little guys, like a mongoose, that pass close by to the camera
- a lot of wildlife photography (especially that of mammals) shows the subject level with, or slightly below, the photographer. I've got bored with this slightly 'superior' feel to wildlife photographs and so now prefer the quirky images that I get from the low angles.
What it does mean though is that I get a lot of leg shots when large mammals walk too close to the camera. Ideally, you might say, I should position the camera further away from the likely path that an animal might take. That's absolutely true but one doesn't always have too many options.
Notwithstanding the benefits of a well-framed photograph I always enjoy my leg shots. I think they often give a better 'sense of place' than would a photo of, say, an antelope's rump.
