I used two photos of the recent supermoon and combined them. The result is OK (link below). I was unable to achieve a look I wanted, where haze causes darker areas of the moon surface to assume the same color as nearby sky, and only brighter areas of the moon stand out. I tried selecting the shadow areas and using "Color to Alpha" in GIMP, but the effect was very harsh. Any tips?
Here is an image I found that is close to what I would like. It is property of Josh Blash (Rye, New Hampshire).
