How a camera works.

Pinhole cameras and SLR cameras can be different in many ways but the same also. Pinhole camera we made in calss have a shutter that you have to open and close with you hand. And count how many seconds you have it open to close it at a certain second. The picture ends up on a photographic paper and you have to put it in chemicals to make that image appear. In a SLR camera you just push a button and VUALA there you go. You dont have to open or close anything at all you just simply Push! Once you push that button thats when the shutter in the camera will open to the amount of time needed on to a film strip.
