    Thank you for the relocation. I'd read the original thread, and though one user mentioned increasing agitation intervals, the rest of the thread was devoted to the recommended 3 minute intervals. And pork and turkey.

    I east both

    More seriously too little agitation causes streaking, bromide drag.

    I find Pyrocat has very good catutance and micro-contrast with normal agitation, I've used less agitation and it doesn't increase by that much (but I done it by accident -not palnned).

    I could give you formulae that will give far higher acutance/edge effects but at the sacrifice of micro-contrast and very fine deail, and with a slight increase in grain. But look at the se prints from a medium distance they look razor sharp go up close and the effect's gone because the fine deatails lost.

    I did a test last weekend with a hassy.

    (A) First roll developed 'normal' as I do it always.
    pyrocat-HD 1:1:100, 20 degree celcius. for 12 minutes.
    first min continious, after that 1x each 30 seconds.

    Second roll.
    (B) pyrocat-HD 1:1:100, 22 degree celcius. for 15 minutes
    first min continious, after that 10 seconds at 4,8 and 12 minutes.

    Conclusion (prints are 24cm x 24cm):
    ------------------------------------
    Both prints are printed at their best. Print (A) is printed at grade 2.5. Print (B) at grade 2. (A) is a little softer.

    -General impression of both prints from 1 meter is equal.
    -Shadow separation is equal
    -middle tone separation in the tree looks a little brighter for (B). But is almost unnoticable. Maybe i want to see something here...

    So for me the method used for roll B is not different than the one I use with much more agitation.

    Remark:
    --------
    I would have expected that the max density of the negative (clouds) would be somethat less dense because of the decreese in agitation, but it looks that with the 1:1 dilution there is enough developer to overcome the 4 minutes between two agitation points.
