This image of a buteo buteo is made with a canon r6 camera and an rf 100 500 lens together with a 2X teleconverter. The photo was taken in the winter with an exposure time of 1/500 seconds at the f14 aperture, which is the widest aperture of the lens at the 1000 mm focal length thanks to the teleconverter and an iso of 640. Also, because the bird is very far away, I had to take another fairly aggressive crop of the picture to get this framing. In photoshop I standardized the exposure and also removed some smaller branches that disturbed the frame
