I've only slightly messed around with one camera ^^;;. Buut even though I don't know what an aperture is, I can understand that at first, the eyes are adjusted to darker lights by having the pupil let in more light... Ohh! Then suddenly the light turns on and now there's too much light to see, for which the pupil needs to take time to adjust for because it's a body part, and then the light goes away before the pupil adjusts. And that's why people only see a flash and not the objects in the room!

Does that mean a less bright pulse of light gives an impression of the room because it requires less time for the eyes to adjust? Or that the eyes don't really need to adjust much but it does anyway and that's why it's harder to adjust back to less light when the pulse of light goes away?
