There are three basic types of wildlife photographs. The portrait, the behavioral image and the environmental image. Each can be spectacular. Beginners shoot the documentary “I saw this”. Usually the image is too far away to be a good portrait and no attention has been paid to story that might have been told. An intermediate is beginning to understand his or her camera operations and how to use them creatively, but they are still primarily trying to get the portraiture head shot. An advanced amateur has begun to understand the concept of a “sense of place” and seeks to tell a story with his or her images and to provided behavioral context or environmental context to their images.
The only difference between an advanced amateur and a pro is time in the field!
