This is a strange question, I've seen talk about Ortho or Litho films before and I have sort of a huge knowledge gap here, I know that some kinds of Orthochromatic film could be developed with a safety light in a darkroom so you could precisely watch when the film was at the exact exposure you wanted, this was before Panchromatic film came out right?
Does this have any relation to Ortho Litho film?
I just got into 4x5 and researching my very limited (from "tiny format" perspective) and a film that stood out on price was this...
at 50 sheets for $10 it's way under the other's price, but it's some kind of "copy" film right? but can it be used to take a photograph and developed as B&W negative? Kind of how others use x-ray film as of late for it's cheapness?
