Make A Digital Pinhole Camera

Digital cameras are easy to convert into pinhole cameras.


A pinhole camera is the oldest and most basic of cameras. It's essentially a box that uses a small amount of light, which comes in through the pinhole, to produce an image on the other side of the box. Remember those large contraptions in old Western movies? Those were pinhole cameras. As cameras became more and more advanced, pinhole cameras were left behind. For fun, you can turn your digital camera into a pinhole camera with just a few modifications.


Instructions


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.
