Well, fortunately I've just found an instruction that came with the bottle of the developer and there is written that Ilford Pan 400 should be developed 21 minutes in the 1:40 dillution at 20 deg. C. So my problem is solved.:)) But thanx anyway, Shel, for your answer. BTW, let me try to explain some points you mentioned:)
>Although it's reasonably well known that there are several formulas for >Rodinal, and most are quite similar, I've not heard of a Foma Rodinal. >Is there any difference between its formulation and that of other >Rodinal formulations? Is it like the original Agfa Rodinal, or the >contemporary Agfa Rodinal, or like another formulation? Well, I don't know the subject very well, but I heard that these are pretty similar formulas. The basic dillution in the instruction, that came with the bottle, is 1:40. Since you are a lot more experienced in the subject, perhaps you'll be able to guess it's formula from the developing times of the different films, presented in the instruction (1:40, 20 deg. C): - Kodak T-Max 100 - 8-10 min - Kodak T-Max 400 - 10-11 min - Kodak Tri-X Pan - 15 min There is also written on the bottle, that it contains 5% p-aminophenol and 4% potassium hydroxide. >Now, about the film. Ilford Pan 400 is not one with which I'm >familiar. Is it local to your area, or do you mean another film, like >HP5+, which is the 400 speed Ilford with which most of us are familiar? >You don't mean Delta 400, or 400 Delta, do you? No, I mean neither Delta 400, nor HP5+:))) I mean Pan 400:)) The Pan family are the cheapest Ilford b/w films. There is ISO 100, 200 and 400 (I'm not sure if there's anything faster). AFAIK, this is something like Kodak Academy, since it lacks an anti-reflection layer. It's, however, of much better quality (great tonality, sharpness etc) than the Academy. It costs about half the price of HP5+ in Poland. > >Finally, why do you want to use this particular combination? I'm just >curious. Is there some set of characteristics that you're looking for? >Is it just what you have on hand <g>? The latter:)) Just because I'm lazy:))) One more question - the temperature of the distilled water that I keep in my room is always 21 deg. C. It's easier for me to develope in this temperature, than to lower it by 1 deg (it's hard for me to maintain such precision). So what do you think - what correction I should apply to the developing time if the enclosed instruction tells as stated above: 21 min. in 20 deg. C (dil. 1:40) and I want to use 21 deg. C?
