This photo is the stacking of five bracketed shots in HDR software. Individually the shots would not reveal what the naked eye sees. The arches were shadowed along with a bright sky in the windows and setting sun on the rocks. A bit much. Each photo was taken with +-1.0EV bracketed aperture and stacked. This is the result. The software is Photomatix Pro by HDRSoft. Taken at Arches National Park, Moab, UT. Speeds vary per shot.
