Huge Bull Elk and Fall Foliage

My favorite wildlife subject lighting comes from a low-in-the-sky sun behind me, but ... wildlife is not always (not often?) cooperative. In this case, the elk was in the shade while the incredibly-colorful background remained in direct sunlight of a setting sun.
 
When the subject is in the shade and the background is in direct sunlight, you are most likely going to have a different white balance for each. Usually, the sunlit background will be warmer in color than the shaded subject. However, that is a difference I sometimes welcome. Adjust the overall white balance for the subject and the background becomes especially warm/golden. This is often an ideal situation for fall foliage, making the colors especially vibrant.
 
For this image, I used an exposure that pushed the red channel nearly against the right side of the histogram (nearly R=255) and let the rest of the image fall where it may. I initially thought I would have a complete silhouette (totally black elk), but there was plenty of light remaining in the shade to work with. While I could have very significantly increased the brightness of the elk in this photo (and did use a +3 shadow adjustment), I chose to keep the animal dark to emphasize the outline.
 
A mature bull elk with a set of headgear this big is ... really big. Creating a very strong background blur while including most of or the entire animal in the frame requires a large sensor camera, a long telephoto lens and a wide aperture. The Canon EOS 5Ds R and EF 600mm f/4L IS II USM Lens at f/4 created what you see here.
