I'm afraid I have yet another post regarding my continuing foray into controlling the c41 process in a jobo. My interest in obtaining optimum results has kept me in my darkroom developing kodak 5" 35mm control strips in two different types of jobo drum - the 3006 series drum (strip is taped to wall of cylinder) and the 2523 two roll drum. I'd like to make sure that I've recognized and mastered all the various contingencies of this process before I start developing film that counts. So far the results are not too promising. The most discouraging results are in the HD-LD spread - it's way too wide and the red channel is weak compared to the green and blue. The following #'s are my latest results in r,g,b respectively (HD-LD differences from aim)..... .02, .15, .13. So nowhere in the family of bizarre plots in the kodak z manual do they show the green channel spiking in this way. In my tests (eight so far) this is not an anomaly. The green and blue channels are consistently high w/ the green densities being as great or greater than the blue. My dmin #'s look good (-.02, -.04, -.02) or so says the tech I spoke to at Kodak. He had the following suggestions; decrease agitation and check the bleach (possibly leuco cyan dye formation). I'm already down to rotation speed 3 on the jobo (the manual suggests '4' for 3000 series drums). I'll post my results for rotation speed '1' later on this afternoon. Re: bleach....purchased at B and H two months ago, no date code on bottle, label on back in spanish, made in Brazil stamped on back label...possibly ballast for half a year on a banana boat! Be wary of this if you're purchasing chem. from b & h! I ordered some fresh bleach from a minilab supply but now w/ this storm I probably won't see it for another week or so. In the meanwhile I'd love to hear some people's thoughts on this.....Has anyone else run control strip tests on their rotary processor?
