Carbon Transfer Printing Of Forgotten Negative

[Andrew O'Neill]

Finally made a decent print from this negative. It was a bit on the harsh side for gelatin silver, as it received stand development. So, I put it away and forgot about it. It's perfect for Carbon Transfer, though! Stand/Semi-stand (in Pyrocat-HD) is a great way to get HP5 to Alt. print. Conventionally developed just won't work...

Andrew:

Quick question: I initially found it a bit puzzling when you added the Vitamin C to water, but were talking about the developer at the same time. After looking at the video again, I think you were neutralising the dichromate with the Vitamin C, but the developer was plain water. Is that the case? An excellent description of carbon printing, I'm finding it fascinating.

Thanks, Peter.

Yes, he was neutralizing the dichromate with vitamin C. Carbon transfers are "developed" using very warm water. The warm water dissolves the excess gelatin leaving only the hardened gelatin which has formed the image.

Thanks for the clarification. Appreciated.

That is correct. The mating bath carries the brunt of the dichromate, and should be neutralised before discarding. The warm water developing bath may have traces (not verified), but I really can't tell.
