I learnt about the SLR Camera. SLR meaning Single Lens Reflex.
When the image is catured and turned upsidedown by the mirror then flipped back up when it hits the screen or film.
Apature. Well that is a weird one, how it works just like the optic nerve. The Larger the Apeture the smaller the F-stop. And the smaller the Apeture the Larger the F-stop.
