Dear All,
I bought the developer above for some sensitometric tests with HP5+ and Fomapan 400.
I've started with the dilution 1:1:100 x 10' suggested by a friend of mine getting the following curves (compared with the same films with HC 110 1+39 x 6'15").

I took the suggestion as starting point but taking a look to the developer data sheet I seeing the two parts, A and B, are never given peer but with a ratio that goes from 1.33 up to 2 (A/B).

The question is: what would, or should, change if I keep the same total quantity of A+B changing the ratio? For example 1:1:100 vs 1.4:0.7:100 vs 1.2:0.9:100?

Thank you.
