I see this a lot when it comes to wildlife photography, photographers going after the big bulls or big bucks and forgetting about the Doe’s and Calves. They are all important and to show a complete biological history of the species they all need to be photographed.
The same rules and practices that govern wildlife apply here. Look for the best light and interesting backgrounds. This was taken on an early frosty morning with the D5 and 200-400 VR. Now if you’ve ever worked with deer then you know they can be pretty shy. You have to be patient and move slowly so that you don’t scare them. Then once you get in position wait for the moment when their ears are forward. Ears back means unhappy, ears forward means alert but also okay. Little details like the ears are important to watch.
