Ferrania P33 developing suggestions

[hoganlia]

A very good afternoon to all.

I've just finish shooting my first roll of Ferrania p33 and I am a little wary about developing. I have two developing chemicals for B&W, Adonal (Rodinal by Adox) and Bellini D96. I've used both with other films with few problems but reading from different sources Ferrania doesn't seem so straight forward. I did Adonal Stand developing for two rolls of P30 and was pleasantly surprised at the result however the literature on P33 is scant unfortunatley. I could stand develop according to Ferrania's info sheet but I would prefer to develop normally if possible. However...

For Rodinal, the Ferrania chart says:

DILUTION 1+25, TEMP. 20ºC/68ºF, MINUTES 8.5/10, I.C. 0,581, PROCEDURE: 4 rotations during the first minute, then 4 agitations per minute
OK.... but I have yet to come across a film with standard development with such little agitation.

I would certainly appreciate any advice on the matter.

Thanks in advance

Joe

OK.... but I have yet to come across a film with standard development with such little agitation.

One agitation cycle per minute is very normal. The regular numbers are one cycle per 60 seconds or one cycle per 30 seconds. Note that "4 agitations" in itself doesn't say much, but in practice, it doesn't matter much either as long as the motion succeeds in achieving turbulent flow across the entire film surface. This will be the case with general inversions as shown in many youtube videos, described on websites etc.
When agitating, keep in mind that the whole point is to actually agitate, so don't be too gentle. Some people do inversions as if they're balancing an egg on top of the tank; there's no reason to be that cautious and all the more reason to be a bit more brisk.

That puts my mind at rest. Thanks. I have been used to cycles giving continuous agitations for the first minute or for the first 30 seconds and that is what made me doubt. Re the last point, I did find myself nervously controlling my agitations when I started developing but that was due to warnings of not over-agitating. Those days are behind me. I now worry about other things instead.
Thanks!

Excellent, have fun processing this film! I can't help you with specific time or suggestions since I've not used this film; I'm sure others will chime in to help out with that bit.
