After hours of searching and getting many different methods i found an easy to follow guide of how to make a pinhole.
So making my pinhole…
1) Finding an appropriate body
This Twinings tin seems right for my camera body. the metal is bound to be light proof and the casing is black. it will also produce nice sized images, polaroid-like.
3) Make Pinhole
4) Make shutter. a flap to control the amount of time light is let in. Must be light proof
Add some decorations or whatever you want, and then you have a camera, simple and free.
