I've been thinking on and off about using Lith sheet film. Looking at the back archives of the alt mailing list [I think that's what it is] they talk about a low contrast developer for use with this film. The writer claims he can get a full 21 steps with Stouffer Gray Scale. Now it's available from freestyle but before I order the thing. What is it?-)) Will I be able to figure it out or should I save my $8? Obviously it's cheap enough to try it out. I get the impression it's some sort of exposure guide for the printing industry.
