There are thousand of bison roaming Yellowstone. I’ve included about thirty in this image, grazing on the plain just in front of Old Faithful Inn. In the background, we see the thermal features creating plumes of steam along the Firehole River. The bison in the foreground stands alone. Because it is the closest to me, it is large than the rest. I use it as to anchor my image. Just behind this foreground layer is the rest of the herd – my transitional layer. The smaller bison contrast in scale to the large bison in the foreground, as well as carry the eye back into the image towards the empty plain and the steaming ground that make up the background layers of this image.
