Upper Antelope Canyon in northern Arizona is a famous landmark well known to photographers. Especially when the sun moves more directly overhead, sun beams penetrate specific locations in the canyon at mid-day. You can tour the canyon only with a guide, who will help a small photo group arrive at locations when and where sun beams appear. The guide can also help keep throngs of other visitors at bay very briefly while a photo group shoots in a location. The canyon confines, the often strong lighting contrasts, and the brief time frames for taking a photo necessitate setting up and composing a shot quickly, and getting the right exposure with little margin for error.
