bichromate gum
Christopher James' new book mentions, as an untested idea, something that I read recently in a Barnet text from about 1898, namely that you can put the dichromate coat on after the size has hardened and leave the paper for some time before putting the paint/gum coat. From memory the Barnet text (too dear to buy) suggested the resulting image would be more contrasty with less highlight details than a conventional gum print. Can anyone cast any further light on this idea, or suggest any starting points for further experimentation? Thanks Don Sweet
