Thanks very much for the info and evidence! I've been toying with the idea of trying E6 for myself, and as I've got some CR200 to process, this might tempt me to give it a go, as I'm very impressed with your results. I've done lots of B & W processing over the years, so I'd be using the Paterson tank method (might need to get a more accurate thermometer?) but my colour throughput has never really justified giving it a go. How well do the Tetenal chemicals keep (both working solutions and concentrate, once opened)? Thanks again!
