Happy Birthday Ansel.
"I was at a loss with the subject luminance values, and I confess I was thinking about bracketing several exposures, when I suddenly realized that I knew the luminance of the moon – 250 c/ft2. Using the Exposure Formula, I placed this luminance on Zone VII; 60 c/ft2 therefore fell on Zone V, and the exposure with the filter factor o 3x was about 1 second at f/32 with ASA 64 film. I had no idea what the value of the foreground was, but I hoped it barely fell within the exposure scale. Not wanting to take chances, I indicated a water-bath development for the negative.
Realizing as I released the shutter that I had an unusual photograph which deserved a duplicate negative, I swiftly reversed the film holder, but as I pulled the darkslide the sunlight passed from the white crosses; I was a few seconds too late!" - Ansel Adams
