I was talking to another photographer yesterday, and they mentioned Pyro staining of negatives after they had been developed and fixed normally, i.e. in a non-pyro developer. They couldn't elaborate on the process, just that they'd heard of it.

I assume that this would involve using a re-halogenating bleach bath, and then re-developing in Pyro.

Has anyone tried this? If so what were the results like?

This could be a useful technique, say if you only wanted a couple of images on a roll Pyro developed. Or it could be the answer to the hardening and fixing problem mentioned elsewhere in this forum. It might even result in a stronger stain than PMK development.

Darkroom Technique's current issue has a complete article on this topic as an intensifier. It works.
