Hi, I am new with Tetenal's E-6 kit and need some advices... I am bit frustrated now previously I used Kodak Single Use E-6 kit, it was simple and easy, but as I can't get it any more, I went to Tetenal's E-6 kit (So called 3-bath, but actually it's 7-bath when including all the washing between each step - not much less than real E-6 with 9 steps). So far my feelings are mixed. The result's are not exactly what I expect and the Tetenal's documentation is a bit poor. The resulting slides tend to be on dark side. I would estimate that they will require 0.5 ... 1 stop more exposure. I am sure that it's not a exposure issue. It's more the issue with either temperature, developing time or agitation. All my thermometers shows bit different values. The temperature I adapted was around the average value (and very near of the temperature shown by two medical thermometers). I set my water bath thermostat for that, so the whole process is done at the temperature 38 (+0.3 / -0.2) degree Celsius. Current process is: temperature 38 deg. Celsius (based on medical thermometers) 2..3 minute pre-heating 7:00 time first developing (I started from 6:30). wash, Color dev, wash, blix, wash, stab. What route should I choose next: Should I go for longer developing times? If so, how long can I go with Tetenal - Kodak suggest maximum 8:30 time, which is barely enough to difference for being equal to + 0.75 stop exposure. Would the raising of temperature be the right route? The temperature can be off from the real value, but I guess that it's within 1 deg. Celsius from the real temperature. How much will the temperature affect the result with Tetenal? Again, the Kodak recommend maximum 40 deg. Celsius. Another one is agitation. I use rotation with ca. 30 rpm. But I don't believe that it is the cause, as with Kodak Single Use E-6 I got equal results with agitating by hand and rotation. As for the calibration, I don't have any kind of control strips, so I am eyeballing the results. I could take some exposures of grey card and then use densitometer to check what the densities are - but I need some reference values. (I should mention that lately I put couple of reference rolls through a commercial lab and results were poor. One film had so high purple cast that it's ruined, others were developed on different day but had really strong magenta cast - so I really do not have high trust for commercial labs..) Then comes another question: To reuse or not? Many Tetenal user's seems to reuse the developer and compensate reusing by extending the developing times. How much to extend? If I interpret the Tetenal's instruction leaflet right, then development time should be extended by 15 sec after each batch of 4 rolls?
