Just some cheap water color paper. I made the two photograms and then the photo of my granddaughter i made from a scanned 35mm negative and inverted and printed a paper negative on glossy paper not a transparent material. Very interested in how that works out because i am thinking about shooting paper negatives in a large pinhole camera. I might try that tomorrow if I have time.
Great!
Everyone has different tastes but I think the paper texture in those looks really nice.
I think you will find that paper negatives from a pinhole camera work very well for salt printing.
Transparency is not necessarily the best thing for a salt printing negative. I make calotypes ( a kind of homemade paper negative ) and when they are made on more translucent paper, I often cover them with a piece of white paper for part of the exposure ( a "diffuser" ) to extend the printing and build up contrast. I learned the trick from someone who knows a lot more about this than I do, and it adds a lot of control over the printing.
Are you adding a little citric acid to your AgNO3 solution? If not, you might try adding some. Maybe start with around 2% and increase up to about 6% until you are happy with the highlights being bright. Keep notes, because different kinds of paper need different amounts of CA.
I'm happy to see someone else here making salt prints and especially from pinhole paper negatives! It's addictive and fun and there are practically infinite variations you can try ( every little thing matters: paper, type of salt, gelatin, etc. ). There is something really special about seeing the print appear, and there is something very unique about how highlights look in a salt print.
