The light is always different in upper antelope canyon. So many variables, time of day; mornings, afternoons, evenings. Type of weather; cloudy, windy, sunny. How many people are in the canyon. All effect what you experience in that short amount of time while in the canyon. This shot is a good example. There were 4 light beams shining in. Two are fairly obvious. You can also see a beam behind the center beam. And it only appeared for a brief moment, but a thin beam seen near the top right.
