Question about dry plates

[mark]

I can’t find the answer so thought I would ask.

Can dry plates be developed as positives like wet plates?

Hi mark
Short answer yes!
But it requires a special developer.....
If you can find a copy of the darkroom cookbook there are a few in there...

so they are not like wet plate where you can go negative or positive. That’s what I needed to know.

Or, you could apply as standard B&W reversal process -- develop as negative, bleach away the silver image, fog the remaining halide, and redevelop. This won't be a reflection positive like a wet plate tintype (those are actually transmission negatives, but with enough density to reflect/scatter light where the image would be dark in transmission, and they're viewed against a black plate surface or backing).
