    Dang it, lost my print out

    I have done a search on two different forums and can't find the answer even though it did exist, and I printed it out.

    I have order efke PL 100 and need start times. I will be developing in tray and a unicolor drum. If I remember correctly the times were 9.5 minutes in pyrocat HD for a normal scene. This film is too expensive for me to just play with development and want a very good idea to start with, as I do my tests.

    Sandy posted figures here or at michial's place but I cannot find them. Can someone point me to the info?

    May I suggest developing by inspection? That's what I do, and is also why I have no times for the combination I use most. 9.5 minutes in 1:1:100 at 20°C sounds about right - depending on scene, target contrast, agitation, stop/water bath, etc...

    But I have no times, since I develop until it looks right!

    The problem is I don't know what RIGHT looks like. I've been thinking about DBI but two things are stopping me. 1)How to keep the pyro from dripping on the floor and everywhere else when I hold it over the safe light. 2)I have to use the bathroom to process and I would not want to think I am missing drips that my two year old could come into contact with.

    I'll keep looking

    Here is the data Sandy King posted on the Azo Forum in March, 2004:

    Below are some recommendations from my recent testing of Efke PL 100 and JandC 200. The information is keyed to SBR reading, but if you don't understand this terminology just understand that a SBR of 7 is for normal outdoor lighting in the sun, or equivalent, SBR of 5.5 is for very low contrast situations, and SBR of 9 is for subjects with lots of contrast.Development is based on rotary processing, with gentle but constant agitation, in Pyrocat-HD with the 2:2:100 dilution. Times for ABC Pyro, though not specifically tested, would be approximately the same with a dilution of 1:1:1:17.

    EFKE PL 100
    SBR Time (minutes)
    11 4
    10 6
    9 7
    8 7:45
    7 9:30
    6 14
    5.5 18

    For semi-stand agitation with Efke PL 100, I use 16.5 minutes at 21 C. I agitate (in a tray) for 30 seconds initally, stand with no agitation for 8 minutes, agitate gently for 5 seconds and stand without agitation for the remainder of the 16.5 minutes.

    Be sure to presoak the film in water for 5 minutes before developing.

    Thanks tom. That is the exact post I was looking for. Now I have a place to start. Now I just need time.

    Mark,

    But bear in mind that the recommended times I posted at the AZO forum are for AZO #2 paper, which has a very long exposure scale. If your negatives are for printing with regular VC silver gelatin papers reduce time of develoment about 10% for the same SBR conditions, and for graded silver papers reduce development time by about 35%.

    I'm aiming for dual purpose negs and will be printing on AZO as well.

    In that case I would recommend that you use the development information for AZO that Tom posted and adjust contrast of your VC paper with filtration. It will not be possible to make a really good dual purpose negative that will print well on both regular graded silver papers and on AZO.
