I had some a couple of rolls of C41 film more or less ruined by a lab, they came with lots of dust and dirt embedded in the film, so it will be impossible to print these negatives in an analog process which is what I planned to do. I would really like to avoid to have these scanned and printed digitally ... I am thinking about re-rinsing the film again with a couple of water changes ... Anyone done this? Will it help or am I doomed?
