I have printed perhaps 50 sheets of MGWT FB glossy, from different negatives, using Ansco 103 (not 130) with the BTA/KBr modification as described earlier, in my post #8. The results are a mixed bag. There is a definite, noticeable cooling off in the deep shadows, and in some of the midtones, but none that I could see in the highlights. As some of you suggested, notably Drew, midtones printed by means of higher contrast grades tend to cool off, the softer ones, ie. those achieved by primarily the green exposure, are resistant to cooling off using this mixture. I would generalise that this developer offers a cooler tone than a modified Ansco 130, but if you print high-key, or if you lack larger shadow areas, you will not notice much if anything at all. Further, the difference between modified Ansco 130 and the original, on this paper, is also negligible. Still, overall, I do like the tone of this modified 103, especially following a brief Se toning, about 1 min to 1 min 20 sec in fresh KRST 1+9.

Interestingly, Ansco 103 (modified, as above) works quite consistently, and it lasted, as working solution, for a week without any noticeable, subjective loss of power—I did not plot any curves, though. The fear, voiced earlier, that it may change tone due to gradual accumulation of bromide does not seem to have been the case for me, but I have not used it for more than 20 8x10 sheets/l working solution (60 8x10 sheets/l stock).

However, I will continue my search, and today I will mix ID-62. I also hope to test DS-14 with the BTA modification, soon. I will report on either.
