    Anybody has any suggestion on this one? I did a lot of search on this forum, but just got few answers. Seemed like not a lot people using this combination.

    I am asking this is because I want to try to do some experiment with FP4+ film to see if it's works better in xtol than in Rodinal (I am using 1:50 rodinal).
    Rodinal is fine to me but the grain is just a little bit more than I expected.

    I am planning to shoot FP4+ at ISO 160, so, any suggestion for how to use xtol, like developing time, working concentration, etc...

    I am using 35mm format.

    Thanks in advance.

    The Darkroom Cookbook does not give any development factors for FP4+ at ISO 164, but the following alternatives are provided:

    Xtol (no dilution): ISO 125--8 minutes
    ISO 250--9 minutes
    Xtol 1:1 ISO 125--10 minutes
    ISO 250--12 minutes
    Xtol 1:2 ISO 125--11.5 minutes
    ISO 250--13.75 minutes
    Xtol 1:3 ISO 125--14.75 minutes
    ISO 250--17 minutes

    You might still shoot it at ISO 160 and, based on the dilution choices above, select a time factor identical to or between the two given for each ISO/dilution factor. For example, since 160 is close to 125, with no dilution you might choose 8 minutes, with 1:1 dilution you might choose 10 or 11 minutes, with 1:2 dilution you might choose 11-12 minutes, and with 1:3 dilution you might choose 15-16 minutes.I have made this type of analysis and comparison before with other b&w films and developers and not experienced any problems or discrepancies.

    Thanks, I will try 1:1 working solution for 11 minutes.
