The arrival of satellite TV saw the virtual explosion of television channels, broadcasters, production homes and content producers. The reason is because cable TV and direct to home platforms have indeed pushed the frontiers of TV broadcasting beyond all conceivable boundaries and onto a global scale. It is not surprising that television networks across the world make use of the utilization of a Green screen.
One of the common techniques that are utilized in television program production is that of using a Green screen in the background of the studio where a particular program is being shot. This is an element of the strategy of chroma key which deals specifically with the removal of certain images in the background of the shot and superimposing this with some other image, which is more suitable for the production. For instance, one can use a screen that’s green in color behind a broadcaster who is reading out the weather reports. When spectators watch the program, the green or blue screen as the case might be is replaced with a weather map or scenes of certain towns or satellite photographs being shown instead.
A Green screen is very helpful for chroma key uses, on account of the fact that the ordinary human skin tone has little components of green in it. This assists in high quality 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 have become invisible when using the other colored screen, making the effect quite peculiar and extremely unbecoming and incongruous.
One of the main advantages of using a Green screen is that it is fairly straightforward to execute as well as being cost effective. If one were to employ a huge plasma or HDTV screen behind the broadcaster, the effect may be wonderful, but the price tag would be far greater 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 easily make a Green screen that can be used in television program production. For this, something as easy as a table cloth can be used. This cloth has to be regularly 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’s evenly 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 suitable color to use than blue for the background, while if the image is of the sea or the sky, green would not be so good. Using a green screen is so a good means of employing chroma key system in television program production, which is preferred due to its simplicity and inexpensiveness.
