    This a VERY nice rule...Maybe a trial with Delta 400 is coming soon (shot @ 400, deved @ 800). I haven't done this film in Rodinal for some time, so it would be interesting

    Delta 400 and Rodinal

    I have only just joined this site, having had exactly the problems exactly you anticipate with D 400. I shot a roll of D400 at a christening. I used a 1:50 dilution and the times Ilford recommend for rotary processing for D400 and Rodinal. The indoor negs were very thin and quite grainy although the outside shots were better albeit still a little thin. I wrote to Ed Buffalo at unblinkingeye.com. His recommendations were to rate D400 at 200 and use a minimum of 5mls of Rodinal to achieve a ratio of 1:50. I had processed in a Jobo rotary processor which he said probably accounted for the grain due to extra agitation as well as destroying the edge effect renown with Rodinal. So a hand tank is the preferred option with Agfa's recommended agitation.

    The Agfa processing times suggest rating D400 at 250 but Ed favours 200 and he appears to be the king of Rodinal so should know what he is talking about.

    As I have yet to put Ed's recommendations into practice and your post is a few months old I would appreciate hearing how you got on with Delta 400 and Rodinal assuming you have now tried it. It may help me when I next load D400

    Thanks

    Just a thought, Morten; not sure about Rodinal but in DD-X Ilford's recommendation of ISO 500 and 9 mins works really nicely for me!

    Having seen your reply led me to 3 pages worth of this thread in varying guises. I am sure I hadn't seen all of these replies before. Maybe as a newcomer I haven't fully worked out how to navigate this site properly.One reply gave a digitaltruth site for combinations of film and rodinal. B Very useful. However most of the info agreed almost exactly with Ilford's own info on the combination of D400 with Rodinal which was what I used but got thin negs. However the Agfa site mentioned by Ed Buffalo at unblinkingeye is different in 2 respects.
    1). It makes no mention of rating D400 at anything but 250 which is close to Ed Buffalo's rating of 200 and the tank/ hand agitation is 18mins at ISO 250 whereas the digitaltruth site gives 17mins.

    Maybe that one extra minute is key or at least it is worth erring on the side of lengthening development.

    The other explanation for my difficulties is that I have always produced over contrasty negs using ID11 without realising it( perfectly possible without other printers to compare notes with) and my negs in Rodinal are normal. However if this was the case then I'd have expected my analyser to have indicated mainly grade 1 prints with ID11 negs and this hasn't been the case.Most of my rodinal negs needed grade 4 which is a first for me.

    So still can't reconcile all my evidence but have probably got as far as I can until I try again.
