The labels also offer a mini-course in photography. As dedicated as Mangelsen is to making images with artistic merit, he’s also passionate about depicting what is actually there in nature. He won’t visit game preserves, for instance, where trainers might release animals for photographers to capture. So the cards are full of tales of a long wait for that Denali moose or a quick sprint out of a car to capture a Great Smoky Mountains fall foliage tableau in those few minutes when the light and the moisture on the leaves were just perfect. And there are also, on the cards, shots of Mangelsen himself in the field, bundled up against 25-below temperatures or being poked by an arctic fox as he waited to shoot polar bears.
