The process of converting black and white movies into color involves digitizing the original film and then using software to colorize each pixel, which is blended together to create a continuous image. In the past, hand-painting was used to colorize films, but this method was time-consuming and labor-intensive. With the advent of digital technology, the process has become much faster and more efficient. The coloring artist can view the movie one frame at a time on the computer's screen, draw the outline for each color area, and the computer fills it in. This allows for more precision and accuracy in the coloring process. Some people argue that colorizing black and white films can enhance the viewing experience, while others believe that it is a desecration of the original work. Despite the controversy, colorization has become a popular method of bringing old films to a new audience.
