Re: Pinhole gums
Hi Diana,
You have to be a little careful that the gelatine doesn't cool of before it soaks into the paper. Also if the humidity drops due to the cold, exposure times will probably lengthen. What problems are you having??

Thanks for posting those, Marek. That is brave of you to post the
originals, too. I like the rich red of those. Almost of my gum
prints have been made with either pinhole, zone plate, or a toy
camera. I made my first couple of gum prints from a lens-based
camera only last week. I couldn't believe how much easier it was to
register from a sharp, well-defined negative. I had no idea.
I do have a related question maybe you or someone else can answer. I
always size my paper, and dry it, outside, and I sized a batch last
week when it was unusually cold here. I had my gelatin and hardener
in one of those electric pots that keeps warm, but I still had to
coat fairly quickly. I've had a lot of gum-printing trouble with
that paper ever since. So is that a known problem-- coating gum, or
sizing, or hanging it up to dry-- in relatively cold weather? Or
should that not make any difference?
