Monobath developer for Direct Positive Paper

[filmamigo]

I am interested in monobath developers, especially for giving a photographic demonstration to elementary school-aged children. I would like to show them how a light sensitive surface can be exposed in a camera, and then developed to reveal an image. I will likely end up using cut film in my Speed Graphic, and processing with a tupperware of monobath (R3/Donald Qualls formula) to demonstrate.

It would be even better to have a positive image to show at the end of the process. That leads me to Harman's Direct Positive Paper.

Is there a monobath formula that would work with Direct Positive Paper? Bob Crowley mentioned on the New55 blog that such a thing existed...

This looks like a replica of your thread of two minutes before. It might be sensible for the Mods to delete this one Saves you having to check both threads for answers

I'd suggest starting with Crawley's FX6a. I did a lot of work & research into Monobaths in the mid to late 1970's and they work extremely well with papers.

Be aware that the Galaxy (Slavich) paper despite its name is not a Direct Positive paper. I'd prefer to use an RC based paper with a Monobath for long time permanence the current HArman Direxct Positive papers is Fibre based.

Thanks Ian for the tip on FX6a.

I have the advantage that I don't need archival permanence, or even anything of a really high quality. As this is for demonstration purposes and experimentation, I simply need a recognizable positive image.

Someone suggested using cyanotype with the class, and that is absolutely my intention. They can made hands-on photograms. The reason I want to play with the Direct Positive Paper is to show them how a camera forms an image. Unfortunately cyanotype doesn't work behind a lens...
