The introduction of satellite television has witnessed the virtual surge of television channels, and broadcasters, production houses as well as content producers. This is because cable television as well as direct to home platforms have certainly pushed the frontiers of TV broadcasting further than all imaginable boundaries and that too on a worldwide scale. One of the frequent techniques that are used in television program production is that of working with a green screen in the background of the studio room where a particular program is being filmed. It is a part of the method of chroma key that deals particularly with the removal of selected images in the background of the shot as well as superimposing this with different image, which is more desirable for the shot. For instance, a person could make use of a display screen which is green in coloration right behind a broadcaster who is reading out the weather condition announcement. When viewers watch the show, the green or maybe blue screen as the case might be, will be obliterated, having a weather map or even scenes of particular places or satellite photos being shown instead.

A green display screen is particularly useful for chroma key functions, on account of the fact that the normal skin tone has very little elements of green in it. This can help in superior level of quality of image superimposition as well as replacing of backdrop, devoid of interfering significantly with the standard view of the broadcaster who may be positioned in the foreground. In case there was any kind of green tint or tone in human skin, areas of the body will have become unseen on making use of the other colored display screen, producing the effects rather unusual and very improper and incongruous.

One of the main advantages of using a green screen is that it’s fairly easy to implement and quite economical too. If one were to utilize a large plasma or HDTV screen behind the broadcaster, the effect can be amazing, however the cost will be quite too high. In these days of economic depression, in which cost management is vital, the dice is loaded in favor of utilizing cheaper options.

It’s possible to very easily make a green screen that can be used in TV program production. For this, something as simple as a table cloth can be used. This cloth must be evenly painted, so that there are no smudges or uneven parts that could stand out once the show runs on air. Anybody can also use a plain wall that is uniformly painted in green to form the colored backdrop. One of many tips to keep in mind when working with such a screen is that if the background image is one of trees or forests, green is often a more suitable shade to utilize than blue for the backdrop, while if the image is of the ocean or sky, green would not be so apt.

Utilizing a green screen is therefore a powerful means of making use of chroma key strategy in TV program production, which is preferred because of its simplicity and inexpensiveness.
