I understand. Rodinal does give slightly more defined grain than say Xtol with a given emulsion- no argument. my statement was this:
Rodinal does not give HUGE grain.
You see my findings are that at lower dilutions say 1:25 Rodinal gives similar grain to ay ID11 (in fact on a 12x16 from 35mm HP5 I can't tell them apart)
I think the assertion that Rodinal is a grainy developer is false, it doesn't give huge grain when compared with other common developers, especially with careful exposure and processing.
I have pictures on medium speed films that show comparatively little grain in Rodinal even in the sky.
Of course there may be some speed loss and you may have to resort to less agitation but in my experience the statement "Rodinal gives HUGE grain" is false, slightly more defined grain than a fine grain developer possibly but not huge.
I don't want this to be a Church of Rodinal vs fine grain dev argument, if you find it too grainy OK I find in practice it is little different to ID11/D76 with my modus.
YMMV as they say
