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?
