Things You'll Need
Instructions
First, spray the entire inside of the can with flat black paint including the lid.
On the can's side, locate the approximate middle point and very lightly mark it.
Using a very small needle put the point on the mark and begin to work the needle through the cardboard side of your can by turning the needle back and forth as if it were a screwdriver.
Stop as soon as the needle just pokes through the other side.
Use your piece of sandpaper on the inside of the container to sand away any edges around the pinhole.
Now cut a 1 inch X 1 inch square out of your index card or posterboard.
Place the square over the pinhole on the outside of the container. Tape down one side of the square so that it can be lifted up and laid down like a flap. This will be your camera's shutter. Keep the flap held down in place with a rubber band when it is not in use. When you do take a picture you will remove the rubber band, open the flap for the necessary exposure and then close it again.
Take your camera into a completely darkened room and place a 4"x6" cut piece of photo paper into the canister emulsion side (shiny side) facing out toward the pinhole.
Close up the canister tightly and take it out to a brightly lit environment to take your picture.
Face the pinhole side toward the subject you want to photograph.
Remove the rubber band holding the shutter flap and open it all the way (you may have to tape it down to keep it open).
After about one minute of exposure close the flap again and fasten it down.
Take out the piece of photo paper in a dark room and process.
