Answer 1

one interesting thing about depth perception is that sometimes, when you see the moon rising, it is near the “floor” on the horizon, perhaps near some buildings or trees. Your brain thinks “wait a second, the moon there near those builds? It cannot be that small”. So the brain enlarges the moon for you. You see a giant moon. You take a picture and here it is the moon small as ever.

So, sometimes you are beeing fooled by your brain, that can render things instantly, at hight “framerates” and mix them seamsly into the “frame stream”.
