I use the Agfa chemicals because they are = packed in smaller amounts. One pack costs me $14 Australian or about $10 = US and will do 4 of the 36 films. I divide the concentrate into two lots, = the only failures I've had have been with old chemicals, so I tend to use = the second lot within a week. The rotary Jobo drum holds two films, and = uses 240ml of the chemicals, so the Agfa packs are ideal in volume. I then = make sure with a good thermometer that the water bath and chemicals have = reached the exact temperature and use 2 initial water bath rinses to bring = the tank up to the right temperature. [Oh I'm not sure its important, but = I always use filtered water to remove chemicals, and one day I hope to = have a rain water tank and filter for all processing]. Timing is the = important thing. I have a Jobo tank with the "lift", and to be honest, I = would not use E6 process without this device. I use a stop watch, and = write down the timing on the set of instructions, so that I do not become = confused. This set of self reminders prompts me to lift 15 seconds before = time allowing 10 seconds to drain and the 5 seconds to fill the tank with = the next chemical. The Kodak chemistry is more complex and although I have = used it, I have not found an advantage over the simple Agfa solution. = Comments? Alastair.
