I enjoy using my fisheye for landscapes. I got it early last year just before my trip to Monument Valley, Arizona (just barely...it's almost in Utah). If there is a strong horizon, I often keep it dead center so that it will render straight and it often isn't evident that a fisheye was even used. Then I may crop the top or bottom a bit to move the horizon. Fisheyes are nice for pulling in a lot of cloud patterns. Of course, there was none of that here. Fortunately, the usually-maligned clear blue sky complements the orange nicely on the bottom of the frame. Nikon D850 with Nikon 8-15mm Fisheye.
One of our favorite local spots - you'd never guess this was in the middle of winter (since we usually have snow and ice at this point). I thought about removing my daughter, but it helps show the scale... though maybe I should change the color of her clothes? Thoughts?
