i think this has already been mentioned via dan heller, but the suggested exposure for the moon is iso 100, 1/250, approx f/4
my holy grail is this stupid stupid tree. i saw it while taking the bus home for the weekend. while crossing an abandoned railroad track, i glanced and found a little three foot tree growing between the rails. a few weeks later, i staged the shot like i wanted it to be and in black and white like my creative vision told me to. turns out that the darkness of the tree was the same as the bushes around it, and the ground. this led to a picture of 90% practically smooth neutral gray. needless to say, that tree still haunts my dreams
