Cruyff in coloured film

 

 

To perform digital colorization, a digitized copy of the best black and white film print available is used. With the aid of computer software, technicians associate a range of gray levels to each object and indicate to the computer any movement of the objects within a shot. The software is also capable of sensing variations in the light level from frame-to-frame and correcting it if necessary. The technician selects a color for each object based on common "memory" colors—such as blue sky, white clouds, flesh tones, and green grass—and on any information about colors used in the movie. If color publicity stills or props are available to examine, authentic colors may be applied. In the absence of any better information, technicians may choose colors that fit the gray level and are consistent with what a director might have wanted for the scene. The software associates a variation of the basic color with each gray level in the object, while keeping intensity levels the same as in the monochrome original. The software then follows each object from frame to frame, applying the same color until the object leaves the frame.
