Light hitting chemicals or sensors, so memory doesn't have to try as hard.

means A picture captured by a camera, recording light as an image.

from Short for 'photograph,' built from Greek roots photo- (light) and -graph (writing or drawing) — so literally 'light-writing.' The full word was coined in the 1800s as chemical cameras emerged; the clipped 'photo' followed soon after, as people tend to shorten whatever they end up saying constantly.
