Digital signals are generated and stored for each pixel of a frame of a video originated material. A computer reads the digital signals and converts them to binary image data by employing a program to reassign color and black component values for each pixel. The component value reassignments performed by the computer are a primary component modification step. The primary component modification step, in one embodiment, comprises component modifications by selected image zones of the video originated images, based on color data within actual filmed images originated simultaneously as the video images. The film origination and video origination are preferably provided by the same camera, with image data delivered for both through the same lens by way of a "beam-splitter" device. The primary component modified digital data is assembled and a secondary modification may also be performed. Film stock emulsion grain patterns are introduced to the images in the second modification step. Digital devices may be employed wherein random or pseudorandom digital noise is added to each image. Alternatively, the modified video image may be videoprojected onto a selected translucent film surface from which the image is videographed, thereby embodying the film grain pattern from the film surface. A digital film recorder may also be used to record the component modified video image within the emulsion of unexposed, photographic film stock.
