Acros 100 semi-stand

I have been using 1:100 rodinal with efke and have had good results. I agitate two inversion every five minutes to 30 minutes.
When I do the same with acros it seems to get much too dense. I am guessing that t-grain films are probably more efficient with chemistry and respond differently to semi stand. What are the rest of you doing with acros?

I have done Efke KB25 in R09 1:100, 20'C, pre wet 2 minutes, agitation first whole minute then 5 inversions every 3 minute, dumping at 18 minutes, water stop.
The result is quite good, maybe a tiny bit low contrast.

Saturday i did the very same procedure with my first Acros, the result looks very similar when looking at the negs and trying to compare densities. Base + Fog is close to the same.
No prints made yet.

Similar type of scenes (snowy landscape by river) but with a bit softer light when photographing with the Acros.

Unfortunately i own no densitometer.

I had good results with Acros in Pyrocat-HD 1:1:150, 25 minutes, 68 degrees, constant agitation the first 30 seconds, then two gentle inversions at 5-minute intervals.

I rated the film at box speed. Scene contrast was a little flat, so you might want to knock 5 minutes off for a sunnier scene. Yummy negs. Very sharp with excellent local contrast. This looks like a great film/developer combination from my first rough experiments.

Acros I treated similarly in Rodinal 1:100 for 30 minutes showed less shadow detail and more contrast. Next time I would add exposure and cut time. Negs likewise were very sharp with lots of local contrast, a bit too much. I blame this more on my technique (I was experimenting) than on the developer. Rodinal is touchy stuff, but I liked the results. Very clean-looking negs.

I have developed alot of Acros in Rodinal 1:150 semi stand for an hour. The results have been consistantly great, not too contrasty and very easily printable, both my conventional and hybrid techniques. I did find that using 1:100 resulted in very constrasty negatives, but the 1:150 seemed to bring it under control quite a bit, very very sharp and virtually no grain.

Hope it helps.

I use Rodinal 1+100 for 18 minutes, shooting the film at box speed in my old cameras. Agitate 15s each minute for first three minutes, then one inversion every three minutes.

This works really well, in both 135 and 120. Good shadow detail, not too contrasty and scans well.

I am quite content with Acros at Rodinal 1+100 with only a single agitation cycle halfway through for an hour.

It takes some dedicated abuse before you'd be able to make Acros grainy.

Almost exactly as I do. I do two inversions every three minutes. I'm satisfied with the result. Maybe just a tiny bit on the soft side.
