That's a tough one for someone with a sibilant SSSSS problem! But we usually try to run a sssolstice ssstory, and I've been meaning to mention this for some time.Very cool. You make a pinhole camera out of a beer can (or an Italian Lemonade Can). You strap it to your tower and leave it out there for six months. Then you develop the film and you get... A SOLARGRAPH.

Very neat picture. I keep wanting to play with some photography stuff but if I'm not even able to melt solder, then clicking cameras ain't happenin either!
ReplyDeleteOK, maybe I'm dense but I just don't get it. The web site says -not- to develop the paper. If the paper isn't developed, how does one get an image to scan and why doesn't the light from the scanner ruin the exposure?

My question exactly (as WB6TNL asked).
ReplyDeleteFrom my memory the light causes the silver halide to separate the silver. Only a small portion gets separated in normal photographic use. The rest is accelerated by the developer.
ReplyDeleteBut given enough light (long exposure) I can imagine the process will take place even without the help of a developer solution.
A fixer bath might be helpful to keep the negative good.
The short exposure to the scanner light is small in comparison to the half year in the "camera"
