OK. Accepted. What is the other ingredient omitted? Apart from the Hydroxylamine Sulphate? The film thickness can be a problem w B&W 2 baths. Agreed.

Some seem quite happy with the 2 bath. I am using a bunch of Fuji 200 here.

The question still applies - would I be better advised to add it to bath 1 or not? (or bath 2?) From your comment it sounds a bit of a non-issue in a 2 bath. (going by other's experience) I want to get out of the 1-hour lab loop as it it takes 1 1/2 hours to get there with 110 film. The only game in town!

Any pointers to your online exchanges?

I really DO appreciate your input. :-)

Hydroxyl Amine Sulfate is a powerful developer preservative. Leaving it out will have some effect, but I can't tell as I have not tested this developer.

I have tested other 2 part developers and processing at low temperatures and I argued this point with Pat Dignan many years ago. He and I exchanged quite a few notes many years ago.
