Originally posted by grhazelton And of course the moon is a sunlit object, so you might start with the sunny f16 rule: f16 and shutter speed of 1 over the ASA, or that newfangled ISO.
Hawki, is the "rule of 500" you cited a restatement of sunny f16?
No ... it's a calculation of how long of an exposure you can take with a given focal length before you have trails on your subject caused by the Earth's rotation. Essentially, if you are shooting a 50mm lens, it would equate to 500/50=10 seconds max exposure
