That is great! Don’t know much about how the pinhole cameras and even the darkrooms operate but pity it’s gone indeed. Just amusing because I was in Toronto just less than two weeks ago :)
That’s really interesting not sure either why it could not be fixed, wonder was it colour paper. I have seen the idea done before love the idea of the hidden camera. Becky link below does a lot of Solargraphs
Something else on the same subject a local Cork based project involving the community in the creation of some amazing solargraphs, a book and a blog. Well worth checking out.
Very interesting, especially how the extreme over-exposure of the paper is dealt with by destroying the paper image by scanning. Very interesting altogether!
