The appearance of cable TV saw the virtual explosion of television channels, broadcasters, production homes and content producers. The explanation being because satellite tv and direct to home platforms have indeed pushed the frontiers of TV broadcasting beyond all conceivable bounds and onto an international scale. It is no wonder that TV networks across the world exploit the employment of a Green screen.
The appearance of cable TV saw the virtual explosion of television channels, broadcasters, production homes and content producers. The explanation being because satellite tv and direct to home platforms have indeed pushed the frontiers of TV broadcasting beyond all conceivable bounds and onto an international scale. It is no wonder that TV networks across the world exploit the employment of a Green screen. One of the common strategies that are used in television program production is that of using a Green screen in the background of the studio where a selected programme is being shot. This is part of the method of chroma key which deals particularly with the removal of certain photos in the background of the shot and superimposing this with some other image, which is more sufficient for the production. For instance, one can employ a screen that's green in colour behind a broadcaster who is reading out the weather stories. When spectators watch the programme, the green or blue screen as the case may be , is replaced with a weather map or scenes of certain towns or satellite images being shown instead. A Green screen is terribly helpful for chroma key uses, on account of the fact the normal human skin tone has little parts of green in it. This provides help in high standard of image superimposition as well as the replacement of background, without interfering much with the general view of the broadcaster who is standing in the foreground. If there had been any green hint or tone in human skin, parts of the body would became invisible when using the other colored screen, making the effect quite odd and intensely unfit and incongruous. One of the main blessings of using a Green screen is that it is fairly simple to execute as well as being cheap. If one were to use a huge plasma or HDTV screen behind the broadcaster, the effect could be marvellous, but the price ticket would be far larger than using a green screen. In these days of depression, where cost management is the key, the dice is loaded for using cheaper options. One can simply make a Green screen that can be employed in TV programme production. For this, something as easy as a table cloth might be employed. This fabric has to be often painted, so that there are no smudges or uneven areas that would stand out when the show goes on air. One can also employ a plain wall that is regularly painted in green to form the colored background. One of the guidelines to remember when using such a screen is if the background image is one of trees or forests, green is a more satisfactory color to use than blue for the background, while if the image is of the sea or the sky, green wouldn't be so apt. Using a green screen is therefore an effective way of using chroma key technique in TV programme production, which is preferred due to its simplicity and inexpensiveness.
