I haven't used Kodalith in decades, but have gotten acceptable results on recent Arista Ortho Litho with a special dilution of HC-110. I should quality that. It was with respect to making black and white internegs from color neg originals in the lab, two step method, where a relative contrast boost was needed in the second stage. I can't imagine myself EVER choosing a lith film for actual shooting; Tech Pan was disappointing enough at that. But I did prove to myself that con-tone images can be made using lith film under controlled circumstances which are clean and free from streaks, blotches, and unwanted fbf.
