Film base: Difference between revisions

*Polyester is very difficult to tear with your hands, it stretches rather than snaps. Obviously this test is not recommended as it requires you to damage the film, though an accidental film break, or a tearing of the [[leader]] or countdown (if there is any) may give you an answer. Just make sure the leader is original to the print, as sometimes a leader or countdown may be spliced onto a print of a different base.

*A poly print may have "Estar" written along the edge of the print, acetate may have "safety". Although some new prints struck from acetate negatives may still have "safety" written on them. So it's helpful thing to check for, but use it along with other identifying qualities.
