Film Capture for Digitization

摘要

As film scanning and digital writing supplement traditional optical photofinishing, image-taking films designed exclusively for scan―printing will be feasible. The properties of color negative films for optical printing are considered with respect to digitization and image-processing steps. A desirable new film feature is recording the scene with increased color accuracy. This is realizable through further improvement in film spectral sensitivity, which is not possible with conventional films intended for optical printing. Digital device spectral responsivities reported in the literature are compared with normal film sensitivities, suggesting significantly higher colorimetric accuracy is available with digital capture. A demonstration of film colorimetric spectral sensitivity is reported.
