Kodak PXR-464 Plus-X Reversal Black & White, Silent Super 8 Movie Film, 50 Foot Cartridge,#7265 ISO 100/80 - USA Film

This is a low-speed black-and-white Panchromatic film. It is characterized by excellent sharpness, fine grain and good tonal reproduction. If exposed without the built-in filter, the film has a daylight ASA of 100. In Tungsten light, again without filter, the ASA is 80, due to the difference in spectral quality of the light. With the filter in place in Daylight, the ASA becomes 32. (Automatic cameras will usually expose this film as ASA 25 with the filter, at ASA 80 without the filter, which is satisfactory).
