Antelope Canyon is just east of Page, AZ near the Navajo Generating Station.
A permit is required to enter either Canyon. Guides are required in Upper Antelope Canyon but a Photographer's Permit can be obtained at the entrance allowing guide-less entry to the Lower Canyon.
The colors of the narrow walls of Lower Antelope Canyon are defined by reflected light. HDR imaging is a must to capture fine texture in both highlights and shadow.
