George,

Nice shot. That is such a magical time - full moon setting at sunset, and I really like the way you captured it.

I had a similar challenge with exposure on the shot below. What I did here was to use an offshoot of Roman's HDR technique off the same exposure. I brought two versions of the same RAW file into different layers in PS and used a brush to mask out the moon. I thought about dropping a moon in from a different shot, but this seemed to work ok.



Anyway - nice shot of death valley! I need to go there some time.
