Our eyes do such a great job selectively compensating for such a bright object without messing everything else up. The camera is like, "what do you want to see: normal sky/stars and blown out moon, or a nice moon and everything else underexposed?"

300mm lens, ISO 500, F9, -2.7 ev, 1/125 sec shot of the moon. The early morning light blue sky is dark blue and a nearby tree branch completely black. The mood is a little over half illuminated, with lots of pock marks near the dividing line.

"Recent discoveries have revealed an entirely new type of cells, called intrinsically photosensitive retinal ganglion cells (ipRGCs). Unlike rods and cones, ipRGCs contain melanopsin, a photopigment that is sensitive to light."

Shedding light on how the human eye perceives brightness

Scientists are shedding new light on the importance of light-sensing cells in the retina that process visual information. The researchers isolated the functions of melanopsin cells and demonstrated their crucial role in the perception of visual environment. This ushers in a new understanding of the biology of the eye and how visual information is processed.
