tuanvo1982 Posted April 5, 2012 Share #1 Posted April 5, 2012 Advertisement (gone after registration) I have done C-41 with 30 degree. The temperature is very reasonable to me but I don't really know can we process E-6 at a temperature under 38 degree. Thanks Link to post Share on other sites More sharing options...
Advertisement Posted April 5, 2012 Posted April 5, 2012 Hi tuanvo1982, Take a look here E-6 processing temperature. I'm sure you'll find what you were looking for!
andybarton Posted April 5, 2012 Share #2 Posted April 5, 2012 You really need to use a thermostatically controlled water bath Link to post Share on other sites More sharing options...
tuanvo1982 Posted April 5, 2012 Author Share #3 Posted April 5, 2012 You really need to use a thermostatically controlled water bath Yes, I have that. But sometimes, the temperature of water bath is different from the chemicals in tank. It is my issue. Link to post Share on other sites More sharing options...
andybarton Posted April 5, 2012 Share #4 Posted April 5, 2012 You must make sure that the chemicals are left in the bath at the right temperature for sufficient time to allow them to get to the same temperature as the bath. Could easily be as long as half an hour or more. Are you having trouble getting the chemicals up to the right temperature, or asking whether E6 can be processed at a lower temp?

tuanvo1982 Posted April 5, 2012 Author Share #5 Posted April 5, 2012 I haven't started with E6 process yet. The E6 instruction shows 38C +- 0.3C while C-41 allows +-1C. In my C-41 experience, I usually start with 39C of chemicals and when chemical temperture goes down to 37-37.5C, I will put more hot water into water bath in order to increase the chemical temperature to 38.5. In addition, I rotate a take 1 per min, However, for E6 processing, temperature is 38C +-0.3 and rotate every 15seconds. It make me concern how to keep temperature at 38C +- 3C correctly. we also need to open the cap of the tank to rotate a stick. Link to post Share on other sites More sharing options...
andybarton Posted April 5, 2012 Share #6 Posted April 5, 2012 Unless you have a Jobo processor, or similar, processing your own E6 really is very difficult. The Jobo has a heater element in the water bath that keeps everything at the right tempoerature. You can't do it just by putting everything in the sink with hot water, as it is very temperature sensitive. My advice would be not to try to process your own E6 unless you have the right equipment.

tuanvo1982 Posted April 5, 2012 Author Share #7 Posted April 5, 2012 Advertisement (gone after registration) Thanks Andy, Yes, I thought so.I will start thinking of a simple jobo (just for heating up and keep temperature correctly) Link to post Share on other sites More sharing options...
andybarton Posted April 5, 2012 Share #8 Posted April 5, 2012 This is the kind of thing you will need, if you continue down this road. Try to buy one with the "Lift" mechanism, as that makes the whole process much easier. http://www.ebay.co.uk/itm/JOBO-CPE-2-Film-Developing-Processor-Kit-/180851922459?pt=UK_Photography_DarkroomSupplies_SM&hash=item2a1b9d561b I have one that I use occasionally, solely for E6. The sight of a full length of slides emerging from the tank is brilliant - more exciting than B&W processing and it's not difficult to do. Link to post Share on other sites More sharing options...

I think jobo rotates the tank. is that not enough? Link to post Share on other sites More sharing options...
andybarton Posted April 5, 2012 Share #10 Posted April 5, 2012 The lift allows you to dump the chemicals straight out of the tank, into a jug, without having to remove the tank from the rotation mechanism. It's very fast and much easier. You then pour the next lot of chemicals into the hopper at the top and they go straight into the tank. I wouldn't have bought one without a lift.

tobey bilek Posted April 5, 2012 Share #12 Posted April 5, 2012 Stabalize with heat soak including tank with film in it. Run a test with an empty tank and see it there is a temp drop when you pour in developer. water substitute will be fine. If you do lose a few degrees, then you need to overheat the developer a corresponding amount with a hotter bath. Only the first developer to critical. The rest are way more forgiving. Years ago I used to set up a 11x14 tray with 6 two reel stainless capless tanks. Then I moved the film from bath to bath with a lift rod. 40 min in the dark is no fun. I moved on to a JOBO. And stay away from the three step processes. The colors are nowhere near as good. Blix simply does not work as well as separate bleach and fix.
