True, but printing Moonrise required a lot of work, particularly to bring the sky down. My situation would indeed involve an unavoidably overexposed moon, falling on Zone X, but plenty of detail would be recorded and I can bring it down with development and printing controls. I've had to deal with significantly higher contrast scenarios so this is not a very difficult luminance range to handle. It's really only the movement of the moon that troubles me.

Another variation on this occured to me. I could do a double exposure using the multiple exposure lever on the camera, and if I do the moon exposure low enough, say zone V-VI, everything else in the scene will receive essentially zero exposure, so even if the film moves slightly out of register between exposures it won't matter. This wouldn't work if there are clouds around though. Anyhow, always challenging out there.
