Preferred developer/fixer for direct positive paper

TheFlyingCamera · Dec 12, 2024

I recently got one of the Pinsta pinhole cameras that is meant to be used with Harman Direct Positive paper. You develop the image in-camera via an ingenious system of ducts and syringes. Has anyone here used one and do you have recommendations for chemistry? The owners manual for the camera is a little light on details about such things.

There's a YouTuber in Arizona (whose name escapes me at the moment, but he has lots of videos on building and using pinhole cameras, some for an Afghan Box Camera, some on RA-4 reversal, etc.) who uses Dektol at normal print dilution of 1+2 or 1+3. If you want to slow down development to be able control contrast with less risk of mottling due to too-short development, you could try Dektol at 1+9 for times more like 7-9 minutes instead of the 2-3 for normal print dilutions.

Thanks! I'll just experiment with it and see what I get.
