    Dektol paper dev ... okay for film?

    I bought some Dektol today (powder mix for 1l of solution) and got it home before realizing it was for paper, not film.

    Before I try and return it, I'm wondering if I can use it for film? I seem to remember people saying paper developer gives way-out grain for film ...
    Those who know, shoot film

    Gives high contrast, I use ilford paper dev for my enlarged negatives because I don't get good deep dark blacks with rodinal or diafine. But enlarged negatives are a bit specialised, I don't know what it'd do to sun-shot normal film.

    D72 which is Dektol was once sold as a Universal developer for plates, films and papers. It isn't a fine grain formula so expect grain if you do give it a try.

    Not the best choice unless you like a lot of grain and high contrast. You could try diluting it down more than normal to say 1+7, or so and maybe tame some of the contrast isuues. Reliable development times are hard to come by, so you're pretty much on your own there.

    I have times in a BJP almanac for D72 diluted 1:1 for press negatives: Dish 4 mins, Tank 5 mins, I assume at 20░C. The times are attributed to Crabtree & Mathews (Kodak)

    For the enlarged negatives I do in Ilford Cooltone (okay it's a really wellused working solution of it, I'm not going to use it for silly film stuff anymore, promise), it's normal paper dilution 1+9 at room temperature which is around 20C and I use 5 minutes in a tray in the dark for fomapan 100 4x5 film. I think 5 minutes is a good starting point.

    Heather, one of the recommended developers for the Ilford Ortho film is Ilford PQ Universal at 1+9, so using Cooltone probably gives very similar results.

    PQ Universal gives good fine grain and can also be used as a normal film developer if diluted further - 1+19 or more.

    Dear IloveTLRs,

    Take it back. Better yet, it's cheap so keep it for making prints. It's just not worth the effort or risk on already exposed negatives.

    I know paper developer is used for lith film but fomapan 100 is panchromatic stuff (yes I bumble around happily in complete darkness). I feel bad using the nice Cooltone stuff that isn't being made anymore so I'll have to try PQ if it lasts as long as Cooltone does. That might be another post entirely anyway.
