It was -10 degrees in Yellowstone when we came upon these frosty bison standing on the trail. This is a mother bison with her calf standing a short distance behind her.
Due to low light, I could not stop down that much to get both in sharp focus, so I used the auto-focus bracketing setting in my Canon R5 to get them both sharp. I focused on the bison on the right (her face) and shot a six-frame focus bracket using increment 1. The first frame focused on the mother bison, and the fourth shot focused on the calf's face. I combined those two images with Helicon Focus, so both are in sharp focus.
The camera on a tripod made this possible, and the bison still helped a lot. I have long used focus stacking for macro and landscapes, but now I find many uses in wildlife photography too! I teach this in my wildlife photo workshops, and many of my clients are using it now to produce wonderful images. My article on focusing stacking is on my website on the opening page. Scroll down to the bottom of that page to find many articles posted describing new photo techniques.[the_ad id="61677"]
