Brian - a former patient of my wife was one of the test pilots chosen by NASA, and was an aeronautical engineer as well, directly involved in both the Mercury and Apollo programs. Although he never went to the moon himself, and remained an alternate astronaut, he was in charge of a lot of the ergonomic designing of equipment, as well as training with it. I've had some fascinating conversations with him. He's still alive and even rented a small plane to fly around a few hours, to celebrate his 96th birthday! But he was never involved with any of the camera gear per se, so couldn't help my curiosity in that respect.
But back to Moonrise per se - I doubt that even the most religious of Zone gurus ever precisely previsualized a print. The whole point is to obtain a versatile enough negative to make life easier. And not until one actually gets to work in the darkroom and spends some time with that specific negative can they start homing in on what it was they might or might not have been thinking about when they took that shot to begin with. It's impossible to instantly freeze-dry the whole mental and practical process. Papers change, personal ways of looking at the same things change. Even the Zone System doesn't preclude an evolution of practical output in print fashion, potentially even within the same work session. I often deliberately print the same negative a bit differently, even on the same day. I might like one version better than the other, or perhaps like both equally well, but for different reasons. That's the difference between a human being in control versus a rote machine. We try to impart our own soul into the print too.
