My right time for 1+9 22C, is 9 minutes. That's for medium format TMY2 in FX-39, EI800. Kaiser condenser enlarger.
I want to use 1+6 for 35mm, same temperature, same EI, same film.
What time would you use?
Thanks!

My best guess is 6-7 min.
Try a test roll first, before shooting something important.
Adjust from there.

I did a quick test at 6 minutes: a bit dense, only in the highlights.
So I kept the 6 minutes, but went from 1+6 to 1+7, with half the agitation: now it's fine...
Thanks.
