So Ive had 2000 ft. of Vision print film in my freezer for a while and have finally decided to get it out to do some testing and figuring out. First in black and white and latter in color processing. The first thing that I've determined is that the ISO rating seems to be around 6, but anywhere between ISO 3-25 will produce a printable negative. First tests produced negatives with many thin negatives. This I attributed to my Konica Autorex not having TTL metering while using a telephoto lens.
Next I attempted black and white reversal using copper sulfate-sodium chloride bleach ammonia, and Ironout as a second developer. I apparently didn't bleach for long enogh, but this was fine as the film seems to be a silver chloride emulsion. The ammonia completely fixed out the film before I got to using the Ironout. To test this I developed a second roll as negative and used the ammonia as a fix. The ammonia fixed out the film and seemed to have a fairly strong blixing action. The concentration I was using was 10 mL of 10% ammonia to 1 L of water. Was this too strong of a concentration? Can anyone confirm that the color motion picture print films are a silver chloride based emulsion?
