Afternoon Bob,
This turned out much darker than it was prior to resizing and shrinking it. There was a lot of noise in the sky. I was both very happy and disappointed with the results. Lots of photo opportunities, however to really draw out the colors, you need either a good sunset or sunrise - otherwise it can be pretty bland. The moonlight is white, and essentially mutes the colors and pulls out the white in the various rock formations.
I am waiting for the fall colors, I really did not see any up there yesterday - however, I did not drive through Oak Creek Canyon.
