Moonlit Cove, Thousand Island Lake. Ansel Adams Wilderness, California. July 27, 2007. © Copyright G Dan Mitchell.

I spent a few hours on this cold, clear July evening photographing the light of the full moon, star trails, and reflections on the surface of Thousand Island Lake.

When using a digital camera to make such long exposures one must adopt a very patient attitude. First, find the spot for your photograph and set everything up in the dark. Then make an exposure of perhaps 15 minutes. Because DSLRs are subject to noise on these long exposures, you then wait another 15 minutes while the camera completes a “dark frame” exposure to determine how to compensate for the noise in the original exposure. Yes, it takes 30 minutes (and lots of battery power!) to make a 15 minute exposure.

You could become impatient. Or you could, as I do, sit back and enjoy the peace and quite of a beautiful moonlit Sierra night.
