    Ilford Pan F plus in Kodak HC-110

    Hello Everyone,

    I was hoping someone could help me out with an easy dilution (maybe 1:50, or 1:100)
    of HC-110 to develop Pan F Plus. I've been using Rodinal for everything, but have now
    decided to give other developers a try. From what I read, I can expect finer grain.
    If you have any comments on the combination, please feel free to share them !

    I'm hoping to get very fine grain, to enlarge (condenser enlarger) to 11x14

    Thanks
    Steven

    (Note: I'd like to work directly mixing from the concentrate, as a one shot developer)

    Hello/Bonjour Steven:

    I used to develop FP-4 in HC-110 dilution B and get very nice results; but it's been quite some time so I cannot recall times/temp, etc. But you might also consider Ilford DD-X. Folks I respect on the OM list speak very highly of it with respect to both grain and tonal scale. I have the concentrate here but haven't used it yet. I have some rolls of APX 400 and Tri-x that will get the DD-X treatment.

    I do like Rodinal and FP-4 for tonal scale and midrange separation.

    Honey, I promise no more searching eBay for cameras.

    I'm not sure HC-110 will give you what you are looking for but you might try xtol 1+1.

    HC-110 dilution E is 1+47 and the Unofficial HC-110 website http://www.covingtoninnovations.com/hc110/ says to use a development time 50% longer than what is recommended for dilution B. Simply dilute HC-110 1:50 and develop Pan-F+ at EI 50 for 6 min @ 68F/20C. HC-110 is very syrupy and is best measured using a medicine syringe designed for cough syrup. They are available in pharmacies for a buck or so. Do not make up the stock solution that Kodak recommends. HC-110 will keep for years undiluted but once diluted to make the stock will keep only a few weeks.

    Thanks Gerald. So if I wanted to try 1:100 dilution, would I just double the time ?

    If you want very fine grain, HC110 is not the best IMO. Paterson Aculux 2 is very fine indeed, as is Ilford perceptol and the like. Both will give very smooth tonal transitions. HC110 is a medium to fine grain developer and will not be poles apart from the rodinal on this aleready fine grained film. Pan F in Aculux 2 is totally grainless and silky smooth, but lacking in edge. HC110 represents the middle ground in terms of grain., with Perceptol/MicrodolX and Rodinal at the other extremes.

    The HC-110 website suggests multiplying the developing time by 2.5x for dilution F (1+79). It also states that you need a minimum of 3 ml of concentrate to develop a roll of film. At 1:100 you would have only 2.5 ml for a 1 roll (250 ml) tank which would not be enough. I suggest that you not go past dilution F. Alternatively you could mix 300 ml of working solution and use a 2 roll tank with an empty reel in the top position to prevent pistoning. I typically use the 1:50 dilution with excellent results.

    Thanks again. I'll give the 1:50 a try.

    HC-110 diluted 1+63 has worked for me with Pan F. I developed for about 7 mins at 24C.

    Another vote for PANF in DD-X. Shot and developed the attached with that combo.
