The Colorado River passing through Marble Canyon, Arizona. Canon EOS R6, f/2.8 RF15-35mm at 15mm f/16. A 3-shot bracket/HDR: 1/15s,1/8s,1/6s. A modest Nik 6 Silver Efex layer mask (10% opacity) applied to reveal some areas of the ancient geologic stratigraphy. A few areas down in the abyss were also lightened a bit. The solid Gitzo Systematic Series 4 tripod saved the shot on this very windy morning.
