does developed film have relief.

Thanks @DREW WILEY David Tatnall at view camera australia where Andy has some great articles has forwarded my details to him.

However I think that dying the emulsion white may be the real stumbling block here.
I haven't received my hydrogen peroxide yet but will have more information on what the bleaching actually does after testing.
A chemical reaction that turns the silver white after fixing the image would probably be a better solution.

I need to find an Alchemist or a real life mad scientist really I think.
Anyway thanks for your help.

Yes, you are entering the realm of voodoo. Perhaps you can do a genealogical search to see if any of your ancestors knew Merlin. Otherwise, get a copy of MacBeth : "eye of newt, toe of frog, fur of cat, tongue or dog...."

But the most important part for me is to create images with the huge tonal range of film ( and carbon transfer )
not the limited one of normal paper development.

I think your quest may be based on false premise then. Why do you believe film has a greater tonal range than paper? I can record a large contrast range, at the cost of producing a scale that's very low contrast if you try to use it as a reflective medium. Would a low contrast paper print be worse for that? I doubt it.

Yes @grain elevator there is a big difference between reflected and transmitted.
However the proof is in the carbon transfer process there is clearly a difference in what is printable there.
Also the relief adds a new dimension as it can do in carbon transfer.
So I don't think this is a false premise
It's a question of tonal separation in the whole image not tonal range.

Hahah @DREW WILEY
Yes but there must be someone out there.
perhaps turn the silver to a stable silver chloride + ??
no thats just silly but there must be a white silver salt that is stable.

I'm just hoping to have a reason to set up an Alchemy sub-forum here.
You think young photographers complain about the curmudgeons now?!!!

Well at least as a useless sleeper.
