>>3359289Developed some E6 a few hours ago, the things I always look out for more than anything is my temperatures. E6 has pretty long steps, the full process takes about 40 minutes.
Your chemicals will cool down during the steps which are somewhere around 6 minutes each, Make sure you have a means of keeping water at 38 degrees celcius. I follow the tetenal manual of inverting every 15 seconds, After every inversion I put the tank back in a container of water. This helps counteract the cooling the liquid in the tank.
For the washing steps I make sure to put on the tap well before my previous step is over. At least my boiler takes quite some time to reach a stable temperature.
I fill the tank with water, shake it around for 30 seconds or so and then dump the water. I don't like wasting water so I don't keep the water running constantly. About 5 fill of the tanks seems to be more than sufficient.
Blix final wash and stabilizer seem to all be quite unsensitive to heat. The tetenal manual claims 36C recommended for blix with a margin of error of 3C, I just put First Developer, Colour Developer and Blix in a water both to let them heat up to 38C at the start. I take out Blix early on and let it slowly cool down outside. I check again to see if blix temperature is still acceptable when I start the Colour Developer, if it isn't acceptable anymore I let it sit in the waterbath for a little longer.
As long as you can make sure you keep temperatures stable for the first developer and colour developer I think you are quite safe. Timing seems to be less critical than with C41.
