This can be > done without a full-fledged darkroom That is right, for "sharpness" an 8x10 contact print is best. Long time ago, I was told: "35mm pinholes images fall apart when enlarged". See how this one falls apart: Warning: 150Kbytes http://members.home.com/penate/originales/big.jpg The above image is the raw scanning (no digital manipulation whatsoever) of an 8x10 print obtained by enlarging a full 35mm format frame, If you use your monitor with a 1024x768 resolution, the above image would show up us a 9X (or so) enlargement of the original 35mm negative. I'd let you decide if it is possible to have relatively sharp images larger than 5x7 from your 35mm format pinhole camera. BTW, the camera was a 35mm disposable camera with a pinhole 14mm from the film, here is a picture of it: http://members.home.com/penate/cameras/14f.jpg Having said all that, unsharp pinhole images like this one, by Tom Lindsay: http://www.???????/pinholer/exhibits/TL.html have nothing to envy from "sharp"ones.
