A pin hole camera is smaller version of a Camera Obscura, it demostrates the basics of photography.
I made my own pin hole camera out of an old biscut tin, firstly and paint the inside of the tin black, cut a hole in the side of the tin where my aperture was going be and taped a piece of tin foil over the hole then poke a pin in making my aperture, then i made shutter out of a pice of cardboard. In order to work my f-stops i need to take a light meter reading. I measured the distance between the aperture and wear the paper was going to be placed the sum of
Focal Length

Apeture = f-stops.
