ZS film testing

[mono]

I need some new testing for Acros 120 in the ZS.

Have you any suggestions how to increase or decrease development times with Rodinal?

10%, 15%, 20% change of times for N- or N+ steps as a start with modern films?

It would help to keep tests simple!
Thank you!

Tests

Mono-the modern films like acros need much less compensation than the older
style traditional ones. I reccommend the 10% for the initial +1 and -1 times. That's what I use and it works just fine.
Best, Peter

Thank you, Peter.

That´s exactly what I heard about modern films. I think I`ll give 10% a try.

Acros again

Mono-and don't forget that Acros has the BEST reciprocity of ANY film which for timed shots actually makes it a faster film than most ASA400 films!!

Yes, Peter, that`s the reason for Acros ;-)
