Not quite 180°, but pretty close! This is the same cooperative Barred Owl from close to home. It was really choosing some great perches to hunt and roost from! I knew I had a decent BG if I walked around to the back of it...only problem is that it paid no attention whatsoever to me, so I had to wiggle my boot under the snow to get it to turn its head! It did so only once, and looking rather annoyed, then proceeded to fall asleep...
Canon 7DII + 500mm f/4 II, manual exposure, evaluative metering, 1/500s., f/4, ISO 1600, natural light, handheld, FF. 2 things I opted to leave in but could very well remove: the peeled bark, and the few snow flakes here and there.
