After printing this out there is more you need to do to make it work. You also must either print it out in somehting lightproof or paint the interior black
After printing make sure the interior is light proof. Tape a piece of tin foil to the front and prick a very small hole in the foil. Cover the foil with a second piece of foil lightly taped so it can be removed. In total darkness cut a piece of light sensitive photo paper to the size of the interior and fit into the camera, place on the lid and tape the lid to block all light. Point the camera and remove the foil flap (shutter) do not move the camera, Replace the flap to cover the hole and then try developing your photo.
