build a digital pin-hole camera

Step 4 Attach to the camera

Once the card is mounted to the bellows, or the pinhole to a body cap, simply mount the bellows or cap to the digital SLR camera. You will need to use a tripod because the exposures are fairly long. Astute viewers will note that the bellows are mounted on an old film camera in this picture. This is because the digital camera was busy making the picture and couldnt be in it at the same time. But it also shows that if you really wanted to, you could also use this set up to make pin hole pictures on film.
