Thanks a lot. This is all good information. However, you
are making a lot of references to paper processing again.
That's not my concern. Can we limit this conversation to
film please?
Nevertheless, the first part was VERY interesting, but I
don't think it applies either.
Here is why:
1. I am using an acid fixer.
2. I am not using a hardener.
3. I am using HCA prior to the fix.
Given that, the diffusion theory seems to work, and in my
opinion, HT-1 is a very good test, despite its
reputation, if properly applied. My comparison to
methelen-blue test verifies that. I just like a bit more
sensitivity, which I was hoping to get from the other
formula.
Do think its worth a try?
You are using HCA _PRIOR_ to fixing? But there is no hypo
present until the fixing is done.
What is the purpose of using HCA in this manner?
Bert (curious)
I think maybe this was mis-typing.
