The only reason that you are taking pictures of the Bengal tigers at the zoo is that you can’t afford the plane ticket to go to India and take pictures of these animals in their natural habitat. And the only reason that you are taking pictures of the Polar bear at the zoo is that you don’t want to risk life and limb by coming within a few meters of these animals in Alaska. The zoo is a nice safe place to take pictures of animals. But the best pictures of zoo animals are those that don’t show the zoo. The fences, the bars, the cages, and other artificial structures of the zoo never fail to make the pictures ordinary. The animals, within the confines of fences, lose a significant part of their appeal. Fortunately, there are four strategies that can remove the zoo background from the pictures.
Three of these four strategies are done while taking the picture while the fourth is done on the computer when the picture is being edited.
