Larry S Moses Posted September 12, 2018 Share Posted September 12, 2018 I have some questions regarding at home Spiral Tank processing. I have been mixing 2 litres of chemistry for 100' rolls of color reversal(ORWO/Svema & Kodak E-6) and, just recently, color negative(ECN-2) 16mm film. After running the first devloper, the solution is sometimes black and seems to effect the image of the bottom 50' layer of film (dark and muddy). Should I only run 50' at a time at the top spiral? Should agitation be constant to mix chemistry, or maybe try to filter the developer before running the other 50'? You advice would be greatly appreciated.

Premium Member Simon Wyss Posted September 13, 2018 Premium Member Share Posted September 13, 2018 The black backing comes off the film. Remove it before processing. Internet search rem jet removal Quote Link to comment Share on other sites More sharing options...
Larry S Moses Posted September 13, 2018 Author Share Posted September 13, 2018 Thanks, Simon. On the color negative, I believed the remjet may be the issue. This also happens with the reversal film as well, which does not require remjet removal. Quote Link to comment Share on other sites More sharing options...
Premium Member Simon Wyss Posted September 13, 2018 Premium Member Share Posted September 13, 2018 Oh, yes, reversal colour films have a jet-black backing as well. Quote Link to comment Share on other sites More sharing options...
Larry S Moses Posted September 13, 2018 Author Share Posted September 13, 2018 Thanks. Do you know if the old Soviet-era filmstocks Svema and ORWO have remjet? Quote Link to comment Share on other sites More sharing options...
Premium Member Simon Wyss Posted September 14, 2018 Premium Member Share Posted September 14, 2018 No, I don’t, but most probably they have. ORWO rather than Svema Quote Link to comment Share on other sites More sharing options...
