Weird title, but it is true.
In a nearly (not completely) dark environment , e.g. when lying in your bed and morning twilight just starts, one can see the contours and patterns of objects, but no colors. The images are a bit fuzzy and grainy. Do you recognize ?
It looks just like a photo taken with very high ISO or and image with a small sensor camera (such as a phonecam) in low-light (but not as low as in this bedroom example).
So do our eyes really work like a camera sensor ?
I know, the camera sensor does not have separate high-sensitive monochrome pixels (rods) and lower sensitive color pixels (cones), but the noise looks the same.

Any ideas on this ?
