Information and discussion on all aspects of British photographic history
As a part of a wider photo history project I am interested in the characteristics of these type of glass plates, sometimes also produced as flexible films. They were introduced from 1895 but were in production in various forms for decades.
I have some comparisons from the 1890s Journal of the Royal Photographic Society and a little from the BJP. If anyone has manufacturers information in particular I would be keen to hear.
