Photograph the Sunbeam or just the rock formations in the slot canyon is very tricky. Due to a tight spaces in the slot canyon, so there's only one spot that you can setup 1 to 3 tripods, and you only have about 5 min. to get the shot just to have enough light reflected from the floor. Also, I want to capture the natural colors of the slot canyon, I have set my WB to 4550Kevin temperature, and manual focusing.
The best way to capture the slot canyon is a SLR or DSLR camera, Ultra wide angle lens, tripod, and a shutter release cable. In the slot canyon is very dusty, so changing lens is not recommended, and no flash.
