I use photographic paper in homemade pinhole cameras. Can anyone explain why
it turns colors? My husband has a theory that it’s pollution reacting with
the emulsion. Here’s an example.

Subject: [pure-silver] Re: photo paper in camera?
One other interesting thing I’ve done, is to put a sheet of photographic
paper in a large format camera, and leave it for an extended period, Hours,
Days… and the paper darkens without development. An attempt to develop the
image will result in a completely blackened sheet of paper, but scanning the
image without development can result in quite a subtle image, often with some
lilac or yellow tones, even though the original paper was BW.
I think the Darkening is the result of what is known as physical development,
but without going back to the literature, I can’t be sure!

Dana,
What kind of speed? Was the paper VC?

Hi everyone!
I was wondering what kind of results one could expect from
shooting photo paper in camera? Is the scale too short to
be useful to scan?
I made several decent contact prints from a paper "neg" in a pinhole camera,
I'm sure I'm not alone. This, of course, suffered from the softening effect
of printing through the paper, which you could surely avoid with scanning,
reversing and inverting the image.
