[LargeFormat] Paper Negatives

[tripspud]

Hi Richard!

      I've seen some interesting pinhole photos made with paper
negatives
and it seems rather easy to do, though I've not bothered with it.  Maybe

there's some published work on it for sure, it's one of the oldest
photograhic
processes, that old book, "The Pencil of Nature".

Cheers,
