Mono Lake by Moon Light, photo by Harold Davis. View this image larger.
In the small hours of the morning, at about 2AM, I stopped at a roadside overlook above Mono Lake and US 395. The bright, full moon was traversing the west above the High Sierra.
Using a smack dab, middle-of-the road exposure histogram (not often my practice), the moonlit scene looked almost as bright as day. You have to look closely to see the stars in the sky, and the only really strong visual cue that this is a night image are the lights of the lone car heading south on US 395.
