The advent of satellite tv has seen the virtual explosion of Television channels, broadcasters, production houses and content material manufacturers. This is because cable TV and direct to home systems have certainly pushed the frontiers of television broadcasting beyond all imaginable limits and onto a worldwide level. It’s perfectly logical that Television networks across the globe utilize the usage of a Green screen.
One of the widespread methods that are used in tv program production is that of using a Green screen in the background of the studio where a specific programme is being shot. This is part of the technique of chroma key which deals specifically with the elimination of certain images in the background of the shot and superimposing this with another image, which is more suitable for the production. For instance, one can use a screen that is green in colour behind the broadcaster who is reading out the weather news. When viewers view the program, the green or blue screen as the case might be, is actually replaced with a weather chart or scenes of particular cities or satellite images.
A Green screen is especially useful for chroma key uses, on account that the conventional human skin tone has very little elements of green in it. This helps in the better level of quality of image superimposition plus the alternative of background, without interfering much with the basic image of the broadcaster who is positioned in the foreground. If there had been any green tint or tone in human skin, elements of the body would seem invisible when utilizing the other coloured screen, making the effect quite odd and very inappropriate and out of place.
One of the primary advantages of using a Green screen is that it is fairly easy to implement as well as being cost effective. If one were to use an enormous plasma or High definition tv display behind the broadcaster, the effect could be marvellous, but the cost would be far larger compared to that of using a green screen. In these times of economic downturn, cost management would be the key and the dice is loaded towards using cheaper options.
It’s possible to easily make a Green screen that may be used in Television programme production. With this, simple things like a table cloth may be used. This fabric has to be evenly painted, so that there are no smudges or uneven areas that could stand out when the show goes on air. One can also work with a plain wall that is equally painted in green to create the coloured background. Among the tricks to remember when using trees or forests as the background image is not to make use of green. Green is often a much more appropriate colour to use if the backdrop is the image of the sea or of the sky. Employing a green screen is therefore a highly effective way of utilising chroma key technique in TV programme production, which is popular because of its simplicity and inexpensiveness.
