Green Screen Use In TV Production
The appearance of satellite television saw the virtual explosion of TV channels, broadcasters, production homes and content producers. The reason is because cable tv and direct to home platforms have indeed pushed the frontiers of television broadcasting beyond all conceivable boundaries and onto a world scale. It is little wonder that television networks across the globe utilize the utilization of a Green screen.
One of the common systems that are employed in television program production is that of using a Green screen in the background of the studio where a specific programme is being shot. This is a part of the method of chroma key which deals particularly with the removal of certain pictures in the background of the shot and superimposing this with some other image, which is better for the production. For instance, one can use a screen that is green in colour behind a broadcaster who is reading out the weather reports. When spectators watch the programme, the green or blue screen as the case might be is replaced with a weather map or scenes of certain towns or satellite images being shown instead.
A Green screen is particularly helpful for chroma key uses, on account of the fact the standard human skin tone has little parts of green in it. This helps in high standard of image superimposition as well as the replacing 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 odd and intensely unseemly and incongruous.
One of the main advantages of using a Green screen is that it is reasonably 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 could be excellent, but the price tag would be far larger than using a green screen. In nowadays of recession, where cost management is the key, the dice is loaded for using less expensive 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 can be used. This cloth has to be frequently painted, so that there are no smudges or uneven areas that would stand out when the show goes on air. One can also use a plain wall that is uniformly painted in green to form the colored background. One of the suggestions to remember when using such a screen is that if the background image is one of trees or forests, green is a better colour 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 so an effective way of employing chroma key system in TV programme production, which is popular due to its simplicity and inexpensiveness.
