Making good wildlife photographs is challenging but it certainly helps to have acclimated subjects to work with. Its one thing to take a snapshot of a deer but to make a good photograph is an entirely different matter. Having acclimated animals for subjects allows one to move their shooting position to take advantage of lighting angles and backgrounds. These images were captured in Shenandoah National Park where the whitetails are accustomed to being around hordes of tourist throughout most of the year.
Photographers working a large buck. Notice the big glass they are using? It is best to uses telephoto lenses that allow the photographer to work an animal from a comfortable distance that does not intrude on the animals personal space. By doing so one can capture the animals doing what they do naturally instead of photos showing them reacting to the photographer.
Pressing an animal too closely will result in unnatural photos. This lady with her point and shoot has invaded this doe's personal space. The does is trying to move to a more comfortable distance but is being followed very closely. Situations like this will likely only result in butt shots and perhaps a stern warning from park personnel.
