    I want to develop some Fuji Acros 100 120 roll film in PyroCatHD using the 1+1+100 dilution. As anyone developed Acros 100 in PyrocatHD?

    I have been looking for some starting times and seem to be getting some wide variations.

    The Big Dev Chart says 16 minutes @ 21 degrees
    The PyrocatHD site says 9.2 minutes @ 21 degrees

    My gut feeling tells me to use the PyrocatHD website times but I don't know who put that webpage up and where the information came from.

    The Pyrocat-HD times on Ken Lee's website are for continuous agitation in a Jobo rotary processor BTZS tubes (actually they are welding rod storage tubes - I have some).

    I process Acros for the same time as all my other films (except Foma) 17mins @ 20ºC 1+1 to 100 inversion agitation, two inversions every minute.

    Based on this then, looks like the Big Dev Chart is not far off. Any ideas who runs the PyroHD website

    For the Foma, I am guessing you develop it the region of 12 - 13 mins?

    Yes around 12 minutes for Fomapan 100 & 200.

    Thanks Ian, I shall use these as a starting point. For N+ or N- would you suggest a change of about 20% in either direction per stop
