Crescent Moon HDR

The crescent Moon doesn't usually look like this because your eyes cannot simultaneously discern such bright and dark regions. The unlit part of a crescent Moon, called earthshine or the da Vinci glow, is visible but usually hard to see because it is much dimmer than the sunlit arc. In our digital age, however, the differences in brightness can be artificially reduced. This image is a digital composite of 15 short exposures of the bright crescent and 14 long exposures of the dark side.
