This long-exposure image was created under a 3/4 full moon about 1 hour after sunset. It allowed the moon to light the seascape much as the sun does during the daytime. The waves have been reduced to a haze and the star trails indicate how much each star had moved during the exposure. It was a warm night and after a while, my eyes became used to the darkness and I could see the faint blue in the sky. This is how it felt to be out here, alone at night in an alien place. In order to get a properly exposed photograph at night, a lot of experimentation is required. In previous outings at night with strong moonlight, I tried exposures from 5 minutes to an hour. 30 minutes is just about right with this amount of moonlight and the aperture nearly wide open at F5 with ISO 50. Under a quarter moon, perhaps an hour is necessary. Changing the ISO to 200
reduces the exposure time and also produces less heat sensor noise, which is different than regular ISO noise. I use ISO 200 now as long as I can get an exposure of at least 10 minutes, to show movement in the stars.
