ABSTRACT:
A process for producing a traveling matte by first converting a first picture including a foreground and a background image to an electronic form into computer memory. Then, converting a second background picture to electronic form and storing it into computer memory. The computer is then used to subtract one stored picture from the other to arrive at a difference image. The shade of the difference image is then changed to a uniform black color, thereby creating an electronic male matte having only black and white regions, which is stored in the computer memory. The computer is then used to change all black regions of the male matte to white regions and all white regions of the male matte to black regions, thereby creating a female matte, which is stored in computer memory. Finally, the stored male and female mattes are converted from electronic form to a photographic material, such as film.
