Green screen works as best backdrop

  1. 1. Green Screen Works as Best BackdropGreen screen or Chroma key technology is a technique for compositing pictures or variousframes into one where a tiny color from one image is removed to enhance the other. Thishappens when the object in front is made transparent so that the object behind it can be clearlyseen. The technique is as well recognized as ‘color separation overlay’. Some although do makeuse of blue color too but green is the best hue since it is sensitive to the sensors of camera whichis able to capture elements that are essential to get a striking result in pictures and videos. One ofthe most common examples to be referred to here is the weather broadcasting where we see themeteorologist standing in front of map however in reality it is a plain backdrop and later thatbackdrop is substituted with world or national map.How the process works?The principal subject is pictured or filmed by making him stand in front of a single colorbackdrop, especially green, which is thought to be furthest away from skin tone. The portions ofthe video, if particularly spoken about using the technique in films, matching with pre-selectedhues are replaced by another alternate video or image. In today’s time, green is the color that ismostly used in backdrops. The green channel contains the least noise and has the capability toproduce possibly the cleanest mask. Also, another benefit that you get by using this color in thebackdrop is that there does not arise a need to have too much of lighting because of its highsensitivity to sensors. The most important part comes when the foreground has to be separatedfrom the background and until now blue was the color that was brought into use. Along withgreen screen backdrops in the kit, there are other tools and a body suit that is worn by the subjectgiven that the person needs to be overshadowed by other objects in the video or picture. Thereare a lot of blockbuster movies which have as well enjoyed the benefits of this technique.
