Antelope slot canyon in Arizona, next to Lake Powell, is an amazing place to capture light and shadow. The photographic tours are led by guides who get you into position with tripods and lenses at the ready for the light show to begin. The Navajo guides know the times in the day for that particular time of year and those particular slots. There is nothing to stop you going on an ordinary tour but you are less likely to be allowed to loiter!
