>>4374189Nb. this film stock (x556 aka Kodalith), when developed as intended with lith developer, has virtually zero halftones. But with the right developer (eg. RLC or TD-3) and procedure, while still contrasty, it can give nice pictorial quality. It's fun to push film past its limits like that.
It was used extensively for backlit animation sequences in the original TRON movie, except they worked with 20x12 inch sheets, and not the puny 35mm lol.
