Last January I had the great pleasure and experience of photographing in Yellowstone National Park. It was an extremely rewarding trip with all kinds of wildlife and otherworldly landscapes, all in one of the harshest of environments.

Though our weather was very good, temperatures did drop to minus 17 degrees on a couple of mornings. Special care is then required for us and for our camera equipment.

One favorite wintertime subject is the frosty bison that inhabit the park. These proved challenging as their dark fur contrasts with the bright white snow playing tricks on your focusing and exposure settings. Though neither image is a prize winner, these are a couple of my favorite bison images from the trip.

Photographer Chris and painter Robin Rohwer each week share a painting or photograph that captured their interest in hopes that it will also capture yours. They have a small studio and gallery in the Phoenix Building at 418 South Gay Street where you can stop and see their work.
