Coloring is done on a computer using a digital reproduction of the film to speed up the process. The film is scanned into the computer, and the coloring artist may see the movie on the computer's screen one frame at a time. The outline for each color region is drawn by the artist, then the computer fills it in. Each color takes about two minutes to complete, so the whole movie can be done in less than an hour.
There are several companies that sell DVD players that can play colored discs. These players have sensors that detect whether or not a disc is color or black and white, and they change their behavior depending on which type of disc is played. For example, if a color disc is played on a player designed for black and white, the colors will appear gray.
The first colored DVDs were released in Japan in 2004. They used a process called "colorization" instead of coloring. With this method, the entire movie is shot in color, but some scenes have been digitally altered with photo-editing software to make them look like they were filmed in black and white. This allows people who have only black and white movies at home to experience them in color. However, colorization does not work on all films because not every scene has been photographed correctly the first time around.
In Europe, there are more black and white movies being made than ever before, so most people have access to both types of films.
Most classic black-and-white films have been "colorized," mostly so that they may be shown in color on television. They use this information along with knowledge of how colors look together to try to recreate those effects in modern photography.
Colorization was first done for silent movies that were shown in theaters where listening to music was not an option. These days, many people get their fix of popular music videos and commercials that feature musicians performing on stage while pictures from the concert or ad are displayed behind them. Colorization helps to make these old films more accessible to a new audience.
It can be difficult to tell what colors are supposed to be in a black-and-white film. One method used by colorizers is to take photographs of the original scene during production with different filters. For example, one photograph might be taken with red filter glass over the lens, another with green, and so on. These photographs are combined using computer software to create a finished product that looks like it was taken with real colors.
There are several companies that do colorize movies, both old and new. It is expensive work that requires careful attention to detail.
A digitized copy of the best black and white film print available is utilized to accomplish digital colorization. The technician chooses a color for each object based on typical "memory" colors (such blue sky, white clouds, skin tones, and green grass) as well as any information regarding colors used in the film. The goal is to produce a perfect representation of the original scene that will not look fake or tinted in any way.
Traditional coloring used watercolors or oils on canvas. The artist would study the scene being filmed and use his memory to select the correct colors. Then he would start painting and once finished, he would show the director what he had done. The director would approve it and that would be that.
In modern times, colorists work with computer software to translate scenes into different colors. First, the camera's raw footage is converted into a digital format. Then the colorist uses specialized software to adjust the red, green, and blue values (color components) of each pixel on the screen. This allows him to create almost any color you can think of. There are also programs that can blend multiple images together to create special effects colors. For example, if there was a blue sky but also some yellow trees in the background, the program could combine these two colors to get a new one - orange!
