The Lower Falls
Yellowstone National Park, Wyoming.
This photo was taken under extreme contrast condition. It was a beautiful sunny day. If I exposed for the canyon and waterfall, the highlights were completely blown out. When I tried to expose for the highlights to retain some detail in them, the canyon and the waterfall were very dark. I utilized a graduated ND filter and it helped somewhat. The rest was done in post-processing in Capture NX2 and CS5. This certainly is a scene to shoot in overcast conditions.
Nikon D200; AF-S 70-200mm f/2.8G VR; Singh-Ray 0.6 Grad ND filter.
