I was stumped by this theme until I started thinking about moon shots I've taken over the years.
The first shot probably qualifies better than any of them for mostly black but I thought I'd use a variety of moon shots for this theme.
The next shot isn't a great moon shot but I liked the way it's shining through the trees and the roof below is covered in snow.
There are wispy clouds over part of the moon in the shot below.
The next shot was actually taken during the day and the sky was blue but I converted it to black and white for the mostly black theme.
The next shot was taken in the early evening.
