    Here is the HP5 processing chart from Ilford.
    Here is the HP5 technical information from Ilford (including information on choosing the best developer).

    I would not use Rodinal on HP5 because of the massive grain that it results in. I would rather go for ID-11 or DD-X.

    Try to contact Sandy King who is quiet knowledgeable about the carbon process, there is also a carbon printing group on yahoo I believe. Rodinal works fine with HP5, since carbon is a contact print process you won't see much grain and with a 5x7 neg grain will not be visible on bigger enlargements. The neg should be quiet contrasty to quote sandy king it should have density range of 1.6 (print well on a grade 0 or 1 paper). So I would add some time say 25% to 50% to the published development times. But as I've said contact Sandy King he is one of the kings of the carbon process.

    Bonne chance

    1 hour stand is possible with HP5 in Rodinal in fact it's currently one of my favourite development forms for HP5. 1:100 is extremely compensating and wouldn't give a good negative for Carbon printing imo. The negative should be quiet contrasty so Rodinal 1:25 is a better choice than 1:100 stand.

    HP5 is my main film. In my experience it is not a good choice for carbon transfer work if you develop it in conventional developers. I've tried it in many developers (including pyrocat), including Rodinol. Of course you can reach a decent DR with conventional developers, by increasing development time but at the expense of higher fb+f. A high fb+f is the problem. You will have more success if you use a high contrast developer such as D-19, which can easily be mixed from scratch. I almost gave up on HP5 for carbon work until Vaughn suggested trying D-19. I dilute it 1:3. Works like a charm!

    Here is a scan of a carbon print (HP5 & D-19 1:3). I scanned this before I had a decent scanner. Believe me, the print is gorgeous, even if the subject matter isn't!

    If you desire a negative which will print well on carbon you need to change to a slower film.
    FP4+ is a beautiful film which is easily developed to produce the tonal scale needed. I use it in several developers with my primary one being Pyrocat HD+.
