Dry Plates in Foma Black and White Reversal Processing Kit

Hello, my fellow esteemed emulsion bakers!

Today I was asked if my dry plates could be used for reversal processing, specifically in Foma B&W Reversal Processing Kit. I honestly have no idea if it would provide good results, other than theoretically it is possible.

Any advice I can pass on?

Regards,
Jason

hi jason
no clue if the foma kit will work, its designed for film emulsion not paper, right ?
i know some folks use hc110 to process your plates ?
so maybe .. they can use your developer and their evertying else ? no clue
ive never done FILM reversals that i can brag or even talk about, so ...
the liquid light tintype developer will work,
as you know its like a monobath developer, carbonate buffer and thiocyanate bleach sort of thing
( if the person is hoping to do this as a single step in camera .
its like a silver gelatin tin/ambrotype glass plates have a greenish tint /funkyness to to them )
the person can always enlarge onto the plates in the darkroom not hard really easy, like developing out paper..
they can look like PERFECT positive images ...

congrats about bostick and sullivan !

Will likely depend on how well hardened the emulsion is - the permanganate bleach is known to soften emulsions quite significantly & a hardening fixer is usually recommended in most BW reversal processes.

The Foma Tech sheet from their site used Dichromate bleach and LQR developer. Much cheaper.

Found it.
