One of my goals after seeing a black wolf in 2018 was to get a better shot showing their yellow eyes. Mission accomplished from my recent Yellowstone trip.
After he came out of the woods with his mate, he stopped and looked in my direction. Great pose for a full frame uncropped photo.
1/1000 sec @ F7.1, ISO 400, manual mode, 700mm, handheld while sitting in a snowbank
He walked to our left and then made his way closer. In this photo, he had just turned his body slightly towards us and looked at me again with his right leg in motion for just the photo op that I was hoping for. He only looked at me for 2 seconds but was able to get a few shots off. The eyes have it!
