    TMY2 and Divided Developers

    I've been using TMax TMY2-400 for a month or so now. I use it for night photography and am generally pleased with the results I'm getting in Xtol 1:1 for 12min at 20deg C, agitation 10 sec/min.

    I would like to see if using a divided developer like D-23 will help me get a little better seperation in my highlights while still maintaining roughly the same overall contrast of the negative . I will also experiment with Xtol at 1:2 and reduced agitation to see if that gives me any compensating effect.

    Is there anything about this film that makes it suitable/unsuitable for divided development?

    Has anyone else tried divided development with it?

    Am I barking up the wrong tree in trying to use a compensating developer to improve highlight seperation; will they generally just reduce the overall contrast of the neg?

    Thanks very much,
    Matt.

    No Matt, I don't think you are barking up the wrong tree.
    I use a compensating developer (Pyrocat) with TMY - it clamps the highlights and gives excellent highlight separation together with good contrast/microcontrast -but you still need to get your exposure right!.
    BTW, I am a contact printer.

    Matthew,
    Do you want to increase the contrast in the highlights, or reduce the contrast ?

    Sandy King has an excellent article in the July/August issue of View Camera on using Divided Developers.

    You may also find that printing on a different paper makes a significant difference. Ilford Gallerie gives superb highlight sparation.

    Ian,

    Thanks for the nice comment and referece.

    Matt, TMY-2 works nicely in a divided developer like D-23. One of the outstanding features of divided development is that with most films a very straight line curve is produced which spreads the compensation equally over the entire highlight range, unlike what you see with some compensating developers where there is severe compression in the highlights.

    The pyro type developers that Tom mentioned also offer a very gentle type of compensation that tames the highlights, but the compensation is primarily produced with VC silver papers.

    I should mention that my article in view camera is specifically directed to those who scan sheet film to print digitally. However, the concept is potentially useful to those who use 35mm and 120/220 film and expose in conditions where there is a lot of change of contrast on the same roll. Divided development was originally developed for this very purpose.

    Aren't those prints a bit hard to see at 1 x 1 1/2? Oh....... :rolleyes:

    After running a test roll in D-76 1:1 I will be heading for the DD shelf for further experiments.

    I'll let y'all know if anything develops. Er.....

    I'd like to get more contrast in the highlights while maintaining roughly the same contrast in the neg overall. I understand that I may find a change in film speed with a new developer and consequently would have to chnage my exposure to maintain the same overall contrast. I would also like to be able to spell "separation", did you have to quote me on that?

    It sounds like it will be worth experimenting with D23 as a divided developer with this film; it will take me a few weeks to get started but I'll report back on what I find. Sandy, I'll be using this to print on silver is there anything different about processing for silver vs scanning?

    All my film is 120 but I almost always use one roll to a subject, the divided development is targeted at maintaing as much detail in my highlights as possible in night landscapes where extreme brightness ranges are compounded by reciprocity failure.

    Thanks for your help everyone,
    Matt.

    Matt.

    Not that much difference. For scanning we want a negative with a relatively low average gradient of about .45, one that would print on silver with a VC #3 filter or so. If you want a higher average gradient you can just bump the temperature up about five degrees and the emulsion can absorb more reducer, which will allow the negative to develop to a higher contrast

    I thought one of the advantages of Divided developers was they are semi-Panthermic so not temperature depenent within about a 6 degree C range.
