I've been contemplating making a simple 8X10 pinhole camera for use with paper negatives. Does anyone know a good source for cheap old/fogged paper? I did a few searches on Ebay and didn't find anything worth really jumping on. Any suggestions on search words? I tried Fogged Paper, 8x10 photographic paper fogged etc, but nothing noteworthy came up.

While I'm on the subject, does anyone have links or plans for a simple 8X10 pinhole camera? I'm not looking to spend much money. While exchangeable backs would be nice, I'd probably start with a camera I could load in the darkroom, take out and shoot, then bring back to process.
