    HP5+ and Pyrocat HD: dilution/time/temp/agitation please?

    Hi!

    OK, I've spent part of the afternoon looking this and I have my fill!
    Got some negs to develop asap but the DDX I have is most surely bad
    now (more than one year) however I have some pyrocat so I was
    wondering is anyone has some starting point on the dilution and
    development time to process HP5+ (120) in Pyrocat? I got some
    Rodinal but I'd rather not use it with HP5.

    I's amazing that most of the info I found here seems to always
    miss some important point: one mentions the time and temp but
    not the dilution, others dilution and time but not the temperature.

    And I process film in tanks. I'm used to semi-stand and stand
    development but I have never used it with HP5+...

    Regards!

    Sandy King, who developed Pyrocat in its' various forms, has published an article on the Unblinkingeye web site:

    http://unblinkingeye.com/Articles/PCat/pcat.html

    There is more information here than you might wish to know but it is important you read and comprehend it all.

    He does provide a development chart for 5+ and just about all popular films of today.

    I rate my HP5+ at 200 asa, soup in PyroCat-HD 1:1:100 for 10 minutes. 15 second initial agg and then 10 seconds every 60 thereafter. 20C water temp, water stop and normal fix. Oh ya, 3 minute pre-soak. I use filtered tap water. My darkroom is 8 feet below ground and I face south when processing film. LOL. One more thing, I develop my film while in the nude. Anymore detail than that would get just a little too personal.

    I do 18' semi-stand, 1:1:100 rated at 200ISO @70f. That's 90" initial agitation then 10" every 3 minutes thereafter.

    I'm printing with a condenser enlarger on VC paper.

    There are a lot of variables, so you really have to test, but it's a good starting point.

    Good luck,

    Will

    I rated the HP5+ at 200 and on a not-so-important roll had a go with 1:1:200 at 20C,
    with first a presoak in plain water for 5mins, water out, dev in, 1 min of continuous agitation,
    then 45min with 3 gentle agitations every 15mins thereafter. Neg looks thin but I know it's a bit
    hard to assess a pyro stained negative so I'll know for sure when I try to print some frames later tonight.
    I print with split-grading on a condenser enlarger with VC paper so I might try your recipe.

    Thank you all for your suggestions.
    regards,
    jf

    HP5+/120, ISO 320, Pyrocat-HD dil. 1:1:100, 12 min. @ 21*C, continuous agitation 1st min., 5s agitation every 30s. thereafter.

    I use a presoak for about 2min.

    Regards,
    Trevor.

    Continuing my little experiment, I tried to print a few frames from my test roll of HP5+
    developped as I mentionned above. Even though they look a little thin on the light
    table, they printed nicely with not much effort of my part. I might use that recipe
    with one more agitation cycle while keeping the same total dev time, 45mins.

    Last night I tried a small variation of recipe that Will mentionned above, a 5min water
    presoak, 1:1:100 pyrocat at 20C and 3 inversions at 17min, 12min, 7min and 2min,
    ditch the dev, water stop bath for 1min, and 5min in Ilford alkalyne rapid fixer,
    10min wash in running water.

    Comparing the 2 sets of negatives on the light table it seems to me that my second
    test yielded slightly thinner negatives. They were done with exactly the same light
    conditions so maybe I was too gentle with my agitations...

    anyways, thanks folks!

    malinmalin, how about rasing your dev temp to 72 def f? That might give you more oomph... Especially for semi stand
