The arrival of satellite tv has seen the virtual explosion of TV stations, broadcasters, production houses and content producers. This is because cable Television and direct to house systems have indeed pushed the frontiers of television broadcasting beyond all imaginable limits and on to a global scale. It’s no wonder that TV networks worldwide employ the usage of a Green screen.

One of the widespread techniques which are utilized in tv program production is that of employing a Green screen in the backdrop of the studio where a particular programme is getting taken. This really is part of the technique of chroma key that deals particularly with the removal of certain images in the background of the shot and superimposing this with another picture, that is more ideal for the production. For instance, it’s possible to work with a screen that’s green in color behind the broadcaster who’s reading out the weather news. When audiences watch the programme, the green or blue screen as the case might be, is actually replaced with a weather map or scenes of certain cities or satellite images.

A Green screen is especially useful for chroma key uses, on account that the normal human skin tone has very little elements of green in it. This helps in the better quality of image superimposition plus the alternative of background, without interfering much with the basic picture of the broadcaster who is standing in the foreground. If there had been any green hue or tone in human skin, elements of the body would seem invisible when utilizing the other coloured screen, making the effect quite strange and extremely inappropriate and out of place.

One of the main benefits of employing a Green screen is that it’s pretty simple to apply as well as being cost effective. If one were to use a huge plasma or HDTV screen behind the broadcaster, the impact could be marvellous, but the price will be far greater compared to that of using a green screen. In these times of downturn in the economy, cost management would be the key and the dice is loaded in favour of utilizing less expensive options.

One can effortlessly make a Green screen that may be used in TV programme production. With this, simple things like a table cloth may be used. This fabric has to be uniformly painted, so that you will find no streaks or uneven areas that would stand out when the show goes on air. One can also work with a bare wall that’s equally painted in green to create the coloured background. Among the tricks to keep in mind when utilizing trees or forests as the backdrop picture is not to use green. Green is known as a more acceptable color to use if your background is the picture of the ocean or of the heavens. Using a green screen is therefore a highly effective way of utilizing chroma key technique in TV program production, which is popular because of its simplicity and inexpensiveness.
