<< Yes, the film you are describing is alleged to be Ilford FP4 in
disguise. In fact, in my experience, it behaves just like FP4 in terms
of exposure, development and tonal scale. >>
This is I think the 4th time I received the same message. Something strange
is still going on with the system.
Anyway, near the end of the catalog there is a section on B&W Sheet Film, and
under it they have commercial ortho (continous tone ISO 80) in standard sizes
(4x5, 5x7, 8x10, etc.), and then they also have CIRCUIT CAMERA FILMS (Pan ISO
125 or Ortho ISO 80) but cut to non-standard sizes. I assume the Ortho
continous for both types are just the same thing?
