This was taken in March 2023, the Antelope Canyon is managed by "Navajo Nation" they do not allow you to take tripods, monopods, light modifiers or models to their tours and the natural light is very limited my pictures were shot at 1600 ISO. If someone want to shot with a model he or she (the model) need to be disguised as another tour participant and wait to the guide to be distracted to take a shot if you are caught they will get you our of the park and I believe they will ban the photographer and the model for a year or two.
Wonderful place, nearby Rattlesnake Canyon is less dramatic, but also less crowded and may be easier to squeeze in a model.
