Goose in the river near Bend Oregon (USA). This photo was made using a solar filter from the 2017 Solar Eclipse. As you may imagine, solar filters do work somewhat as heavy-duty ND filters (should note that that doesn't work both ways; you'll melt your camera if you photograph the sun with an ND filter).
The resulting photo comes out pretty orange, so I converted it to black and white. If I had spent more time, maybe I could have come up with a color image, but you know... I'm just lazy. :)
Settings: ISO 100, f/8, 176.0 s.
