Kodak Dektol question

    Is this developer for B/W paper only?.....or is it for B/W film also?

    The reason I ask this question is that I am going to make some contrast
    reducing masks using 4x5" TMAX100 film. For masks I need a soft developer
    and I was told that I could use Dektol in anout 1:30 (stock dilution and
    water) and then about 3 min. development time.

    Does it sound right?

  2. It will develop film. It is somewhat similar to D-19, but even faster
    acting. It acts very quickly and produces rather coarse grain.

    I've never heard of diluting it 1:30. I'd be afraid of uneven results.

    What do you think should be the about right dilution for TMAX100 then?

    This 1:30 dilution is one that I use in making unsharp masks. However, I
    do not use TMAX for my masks, I use an ortho film, which is far cheaper.
    With enough developer solution, say an 8 x 10 tray's worth and constant
    agitation I have not had a problem with uneven development. Of course
    you could increase the dilution to 1:15 for instance, and adjust your
    times accordingly. Your goal is to get a mask that serves its purpose.
    This may be a very thin mask with detail almost everywhere but the
    highlights. The general rule is that the stronger the dilution the
    higher the contrast of the mask. Also, you might try varrying the
    development times, one for a minute or minute and a half, one for two
    minutes and so on and see which combination produces the best mask for
    the negative you are working with. Good luck.

    Thank you.
    There are many variables to control for a first time contrast mask maker.
    But I see
    no other way to improve the quality of my Ilfochrome prints.

    All I can say is I used it once by accident, thinking I was grabbing HC110.
    I diluted 1 to 7, same as for HC110 solution B. I was developing Ilford
    FP4+ pushed to 400--about half way through developing I realized what I'd
    done, but continued 'til 9 minutes, which was short by a couple minutes, but
    then I conceded I didn't know what I was doing. I stopped and fixed and was
    pleasantly surprised to see workable images. High-contrast, but workable
    all the same.

    Max,

    Using some info from Barry Sherman and Howard Bond, I have been making
    unsharp masks with 4x5 TMX developed in Rodinal 1+30 for about 3 mins.
    (You will have to test a bit to find the best time for your situation.)

    This is a good use for any old Rodinal you have sitting around and are a
    little shy to use on film that may contain that "once in a lifetime"
    image. ;-)

  8. Dale, learning unsharp masking is something I need to do... Any suggestions
    for a tutorial?

    I got a PIN register system from Lynn Radeka......he has a homepage where
    it can be ordered. In the documentation is described how do make the
    different masks (Contrast masks....unsharp masks....fog masks....shadow
    masks...ect).
    Also the book "Post Exposure" by Ctein describe how to make a contrast mask
    (which is
    no exactly the same as a unsharp mask but they are closely related).

    Try Lynn Radeka's website. You can find him at:


    http://www.RadekaPhotography.com

    He provides a kit with a tutorial and he also offers workshops. That is
    how I learned. Good luck,

    Dale
