I call this the Tinhole Camera. It's a 35mm homemade pinhole camera made from a small rectangular tin box. The box holds a deck of playing cards and measures (roughly) 5 1/2" x 3" x 1 1/4". As luck would have it, it was a perfect size for this project.



The pinhole (~f/128 ) is made into aluminum foil and taped to the inside of the box. There's a small hole in the back of the box as shown.
