Digital compositing signifies a process in which two or more images are combined in a way that it results in the creation of one final image. In general, the process is used for digital filmmaking, printing, creation of motion pictures as well as for adding the technical flare to screen displays. Digital or photo compositing is often considered an art form where multiple images are combined. You may have seen the compositing in situations when an actor moves against a background that does not appear real. In motion pictures, the compositing is used to shoot action sequences. The technique used in the process is called the blue-screening. By using the screening methods, the actors perform all the scenes or stunts against a solid green or blue background. The background is later replaced with different background.

Digital ...
... composting is an art form that requires a specific level of skill set to accomplish it perfectly. The bright green spill over is strategically placed in a frame that gives an impression that the actor was shot in a different location instead of a movie set. These shots are taken to the editing room, where green background is replaced by using the transparency filters. The filter works in a way that anything in the shade of green or blue is made invisible, leaving the editor with only the shot of the actor.

As soon as the editor removes background and replaces it with a new one, it appears as if actor has given the shot in a difficult terrain. A great deal of skill set is required in digital compositing to place the actor strategically in a frame. It may appear easy on the surface but it is one of the most difficult jobs involved in film making, and several Hollywood production houses hire experts for the purpose. In the present times, this technique has emerged as a niche, which is an absolute must for the movie making industry. Nowadays, many individuals are making use of the Chroma key techniques which is much easier to use and offers desirable results. With the use of this technique, it is a cakewalk to remove one color or a range of colors from one of the images so that the image is made transparent.

The digital composting and chroma key techniques are often used in regular weather forecast in the television channels. You can remove background and give an appearance that the presenter is standing in front of a large map. However, in reality, the presenter stands in front of the green background. Maps of the world are added as reference for the viewers. While shooting for digital composting, it is necessary for the presenter to not wear anything in the shades of blue or green, as it will not be recognized during the green spill over technique. You too can use the technique to give a new look and feel to your pictures. Get rid of wrinkles and variable lighting by the wise usage of chroma key.
