Late October and I was up very early in Moab in order to make the drive to Mesa Arch for sunrise. On arrival I had to wait in line with other photographers who had the same idea. Finally I got a position, shoulder to shoulder but worth the effort in order to get the photo I wanted. Camera was a Canon 5D Mk III with a 16-35 f2.8 lens at 20mm. Settings as follows. Aperture was 18, speed was 1/5 sec and ISO was at 100.
