this image was captured on the Chesapeake Bay in Maryland in February 2019. It was snowing and I was in waders with my RRS tripod and gimbal head to get an eye-level shot. I used a Nikon D5 with the Nikon 180-400mm f/4 with the built in 1.4 tele-extender. The effective focal length was 560mm. The image was captured at 1/2500 sec, ISO 8000 and f/8.
