Though not nearly as dramatic as Upper Antelope canyon, Sheep's Head Slot Canyon is far less visited. Along with the guide, we had the canyon to ourselves this morning. Reflected light from the red canyon walls create a very warm light on this piece of driftwood and the worn rock around it.
When shooting in dark slot canyons, it is important to avoid getting directly-sunlit areas in the frame as they will result in unattractive blown highlights.
