Negative Intensification

I've been reading up on negative intensification using selenium toner and have a few problem negatives I'd like to try it on. Before doing so, I have a question: If the film was fixed with a hardener, will that limit or prevent the intensification process?

I just re-read Adams' Negative, section on intensification, and there

is absolutely no mention of hardener affecting the intensification.

Though I know with prints it sometimes seems to take a little longer,

and sometimes the toning doesn't seem to be as strong as normal, but I

have only used hardening fixer in prints a couple of times. So I would

go with Adams if no one else posts in the next little while.

Greg,

That generally should not be a problem. I get around issues of that

nature by going through a short pre-saok before my selenium bath. 3-

5 minutes in water should do the trick.

I have intensified negatives after hardening with no problem.
