This was my first trip up the 40 mile Poudre Canyon, and it didn't disappoint. This shot taken September 22, 2017 at 10:32 am. Shot using Canon 5D Mark III, Canon 16-35 mm L lens with a B+W 110 ND 1000X Neutral Density filter, Gitzo tripod Giottos head, shutter release.Settings used were ISO 100, 35mm, f/20, 15 sec. This is a 10 stop filter, which is almost black to look through, but with such bright conditions, the only way to get smooth flowing look. Before attaching the filter, scene had to be focused, lens switched to manual, then attach filter. Very pleased with the result.
