Let’s face it: much as I’d love to try my long lenses photographing wildlife on an African safari, I’m much more likely to photograph exotic animals at the local zoo. And that’s okay, I say, because a beautiful photograph is a beautiful photograph no matter where it’s made. If you’re planning your own zoological photo safari, there are a few special precautions to take. True, you have a much lower chance of being trampled by a rhino at the zoo than on the open plain, but there are other problems. Things like enclosures and power lines and other manmade structures that sort of spoil the wild appearance of your wildlife images. To do a better job of eliminating these, use the longest lens you can and create the shallowest depth of field with a wide open aperture.

It may not offer advice on wildlife photography in general, but it does prepare you for the specific challenges of photographing at the zoo.
