I've ordered some HC-110. The plan is to use dilution H, giving me 10 minutes for HP5+, 4x5. I currently use Tetenal Ultrafin 1:20 and Ultrafin Plus 1:9.

With both, I get consistent results, with the agitation the same for both developers.

Will I need to change my agitation for the HC-110? Most of what I've read here confuses me somewhat, with differing opinions and the case being made for and against its use. The dilution H time is 10 minutes, while my Tetenal times are 13 minutes.

It would seem that slightly reduced initial agitation, and the same intervals would produce similar results to what I'm getting now.

Does that make sense, or am I out in left field somewhere?

Thanks!
