Darkroom Based Options for Positives for Gumoil Process?

analog65 · Oct 19, 2016

Hi, I don't use any computers in my photography, and I would like to try making some gumoil prints.

I don't have access, nor do I want to make a positive film on Pictorico using a digital printer.

The rest I am sure I can do, it is just this issue of needing a positive that is holding me up at the moment.

What are my options??

Thanks

Andy

Maybe enlarge or contact print your negative onto paper, lith film, or x-ray film. I know some people use reversal process on their LF negatives. Have fun!

Couldn't you use something like a lith film (like Arista Ortho Litho Film) to create a direct positive transparency from your negative? Depending on the developer used, it can be used to make a continuous tone positive in addition to the high contrast one it is conventionally used for.

Edit: Oops....Should have read Ned's reply first, he did mention lith film.

Hey NedL and nmp, thanks for your advice. I was thinking of ortho film, but I had not even considered X-ray film. This is why I love APUG so much. I have made large format contact prints from an RC paper negative, so that may be a real option too. I will have to think about this a little bit and then I will circle back when I make a decision and give it a try.

Thanks

Isn't there any way or a process by which you can delaminate the paper backing of the print to leave you with a much thinner image bearing layer? Not that I have seen anything like that....

I have played with that approach before and I personally found it a nightmare and really unnecessary. I have been able to make very good contact prints from RC paper negatives and lately I have been waxing fiber papers for transparency. Based on what I know, I will most likely try waxing some single weight fiber paper (Slavich) and see what type of Gumoil print that will make. Only some testing will reveal some answers for me at this point.
