> the light is coming from all the light sources in the universe, plus the moon
replyAnd all the others are negligible by many orders of magnitude compared to the moon. So it's really just the moon as far as this photo is concerned (except for the small sliver that's still illuminated by sunlight, including refracted sunlight).
> the light is coming from all the light sources in the universe, plus the moon
replyThis is true for every photo ever taken
so the atmosphere acts as giant lamp lit from behind by Moon? never thought of it that way
reply> the light is coming from all the light sources in the universe,
replyThat's highly incorrect. I have many lightsources that aren't contributing to any photons in that picture. For example my refrigerator light.
I turn off my refrigerator light after I close the door by reaching in and pushing the button. Don’t you?
