25 Aug 15. The NE section of Yellowstone is where the large herds of bison are to be found, although they do tend to occupy the vast majority of the park in herds of lesser numbers. This shot was taken in mid afternoon with the herds generally staying close to a central spot, in this case a small pond providing for a nice drink, with the red dogs having an opportunity for a little romp, a nap after a nice lunch from mommie, or both. This is one of my favorite times to photograph them as they are moving only slowly if at all, really don't care if you are nearby, and offer opportunities for interesting shots. There was an afternoon storm building in the distance but moving in to where we were as can be evidenced by the activity on the surface of the water. I had been concentrating on the animals for most of the shoot but noticing the storm building up tried to get a few shots with emphasis on it as well as showing off the differences in the terrain.
The base image was adjusted for max tonality, given some contrast enhancement, and then converted to B&W. The conversion resulted in a very bland image, so I did a few curves adjustments with masks to constrain the adjustments to specific regions.Nikon D300s; 18 - 200; Aperture Priority; ISO 200; 1/800 sec @ f / 9.
