Scope: This standard specifies the method for the determination of the ISO sensitivity of color negative-working camera films for still photography. The color negatives obtained from these films are mainly used to make reflective color photographs, but can also be used to make color transparencies. The sensitivity obtained by applying this standard can be used in exposure tables, exposure calculators and exposure comparison tables during actual shooting. This standard does not apply to cinematography and aerial photography and to color negative films for making intermediate negatives.
