Green screen technology or Chroma Key is a technique which helps in compositing pictures or various frames into one in which the color of one object is hidden so that the color of another object gets enhanced. So the object in front made transparent in order to make the object behind, visible. This process is popularly recognized as the color separation overlay. Although blue color is used for this technique, but it is the green color which is mostly preferred since it is sensitive to camera sensors. In pictures and videos the Chroma key technology is used to give certain effects, and this is made possible with the help of various green screen kit objects such as backdrop, lights and body suit.
A green backdrop is used if the subject has to be removed from the picture, and for this the subject is made to wear green colored clothes. The matching color of the subject’s dress and the backdrop helps in hiding the subject by replacing an object in its place with the help of a green screen video editor. Green color is farthest from human skin tone, which is why the color is used extensively. The green channel has least noise and is capable in producing the cleanest mask possible. With green color used in the background, you will not have to arrange for extra lighting due to its high sensitivity to camera sensors. The green screen is most commonly used since it is different from the human skin, which makes it possible for an exceptional technique so that the subject can be separated and replaced with another object. The most essential part comes when the foreground has to be separated from the background.
When the subject is made to wear a green body suit that matches the backdrop, the subject can be made invisible with a green screen video editing software. A lot of times photographers have various creative concepts in their minds, but due to a strained budget, they are unable to realize their ideas. A green screen studio is easily affordable, which offers the freedom of manipulating a picture the way a photographer wants. For instance, by placing green backdrop a picture can be clicked and later a picture of wild safari can be replaced for the backdrop. This will add life to an otherwise dull and boring photograph. Similarly, various other effects can as well be used to enhance an image or a video drastically.
