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.
