My wife and I made an oatmeal-box pinhole camera this weekend as a lark. After some experimentation with exposure times, we started getting some images to turn out, but even when they worked, the image would only be on one small part of the photo paper. Here are a few examples:

Does anyone know why this might be happening? Is the pinhole maybe too small?
I know the first one's not dark enough; this was our first attempt at developing our own photos, too. We'll get better at that; I'm just curious about the image being so small on the 5x7 photo paper.
Thanks for any help you can provide! |

Aluminum foil also works great. Cut a larger hole in you box then cover it with the foil.

The pinhole should be made in very thin material. Otherwise, vignetting may occur because the pinhole acts somewhat like a tunnel. I use thin brass sheet, available from hobby stores or as shim stock from auto parts supply stores. Aluminum from beverage containers works fairly well. A site with much useful and interesting information on pinhole photography is http://home.online.no/~gjon/pinhole.htm. |

I haven't researched or experimented with DIY pinholes, so I'm not a good source of info on this. But, you might take a look at this page:
http://www.pinhole.cz/en/pinholecameras/pinhole_01.html
to check whether your pinhole is the right size for your oatmeal box. Other pages on that site provide additional info that may be of help, as well. |
