Always there is the question how development variables affect our negatives.
It is nearly impossible to foresee all effects, so you should make notes of your parameters, change them one at a time and work precisely.
Remember :
Increase contrast
with temperature up,
with time up,
but beware : less sharpness may result and the highlights and shadows may suffer.
with agitation up
with concentration up
but beware : grain may become pronounced (e.g. Rodinal 1:25)
This is just an handbook of notes from me and others.
No info about grain, I just got a negative with printable density.
Agitation is 30 secs continous and than every 1 min 3 inversions
A few lab links :
Adox CMS 20 II AND Rodinal
I was not happy with the excessive contrast and near total lack of mid-range tones when I used CMS 20 the first time a year or two ago.
I figured that Rodinal is really the most versatile chemical.
What I did with this most recent roll was expose it at 6 ISO (it’s box speed is 20kk, but who believes that).
6 seems right for my tastes.
I diluted the Rodinal to 1+200 … approximately ‚
Didn’t pay attention to temperature. 20 minutes semi-stand
(1 minute of agitation at the beginning; 1 minute at the 10 minute mark).

a friend wrote this:
„FP4+ (@ 80 ASA) in Rodinal, 1+50, 12:00 Min. (19,5 Grad, Bewegung: In den ersten 60 Sek. permanent, dann alle 30 Sekunden ein vollständiger Kipp).
Zur Entwicklung in Rodinal: Bekannterweise arbeitet Rodinal schärfer, akzentuiert aber das Korn. Während das bei MF keine (grosse) Rolle spielt, sieht man das Korn eines KB-Negativs deutlicher (was m.E. bei manchen Motiven durchaus seinen Reiz hat). Die Geschichte, dass Rodinal brutal körnig arbeitet, stimmt so nicht und hat ihren Grund in der häufig fehlerhaften Verarbeitung. In Rodinal gebadete Filme kommen sehr schön, aber immer l a n g s a m kippen und niemals 20 (oder gar mehr) Grad, besser 19 bis 19,5 Grad.
Meine Entwicklungszeiten sind ca. 20 Prozent kürzer als die Waschzettelangaben, aber ich belichte den FP4+ nicht auf Nennempfindlichkeit (die er übrigens ohnehin nicht bringt!).“
In an old Leica M3 DS (build 1956) I shot the
Ilford HP4 125.
I used the sunny sixteen rule, my light meter forgotten.
Dev time 10.15 in 1+9 spürsinn P3 gave nice negatives.
I agitated the first 30 seconds and then every min 3 times. Temp 20 degrees.

Delta 400 and generally Ilford Films in D76 are good
Streetpan 400 is real 400, loves bright sunlight, Rodinal
Delta 3200 ca 1600 ISO
Retro400 S is 200 ISO und yellow filter gives black sky
HP5 to 1600 (TriX curls to much) super good.
FP4 to 200 is good
Tmax Dev is good compensating dev for pushing
Ilford microphen is good for HP5
Diafine is great for pushing every film. 3min per solution, light inversion, eg stir, never let B contaminate A!, lasts forever.
Pushing to increase contrast, pull for ethereal look
