- 1). Drill a small hole in a lens cap. Make the hole near 1/75 of an inch in diameter or the smallest you can get with a drill. If it is a little larger than this, it will still work fine as long as you make the hole in Step 2 as instructed. Purchase a few cheap lens caps at a local camera store for backups in case you make the hole too much bigger than the recommended size.
- 2). Puncture a hole in a piece of foil using a pin, so that the hole will be as small as possible. This is the hole that the camera "looks through."
- 3). Attach the piece of foil to the lens cap, with the two holes lined up.
- 4). Secure the foil and the lens cap together with electrical tape.
- 5). Place the modified lens cap on a digital camera to create a digital pinhole camera.
- 6). Set the exposure to a much longer time than is normal for your camera. Experiment with the different settings on your camera to determine what exposure length works best for the amount of light coming in through your pinhole.
