I am not a pinhole camera user but this is very intriguing.

This is fascinating. Color image from b&w paper and three month exposure. Bill Barber

Bill, Thanks for posting this. This is fascinating. I wonder what the reciprocity compensation is on that exposure?

I'm thinking this would work with blank newsprint, but I haven't tried yet. Newsprint fades from exposure to the sun, causing a variety of different colors to appear on what was white paper. I've been curious as to whether this effect could be used for a very-long-term exposure, and I guess the answer is "maybe" lol

From what I was able to find on Google, the paper is treated with a stop/fix/develop process prior to exposure... Is this correct. Then apparently the image is actually captured of the paper with a scanner?

It's a neat effect. I'd love to hear how it's done, if there is anyone motivated to pursue the details of the process.
