The images above beg the question, "Why not shoot two exposures - one for the clouds, one for the moon - and combine them?"
Here's one, plus a rough GIF animation that breaks it down (click to enlarge).
There's a full moon coming soon (8/26/07). Would there be interest in a thread for those who are interested to post and discuss their own August, 2007 full moon photos?
