Whenever you see the background scenes or behind the actual scenes in movies ever wondered what are the green and blue screens are that you watch behind actors? Those are used for a technique called chroma key. Chroma keying is a technique that is used in the post production of visual effects or VFX. Using chroma key the green/blue screen is replaced with the suitable screen elements.
VFX or visual effects gives the editor the liberty to switch anything on the screen. The action movies and galactic scenes would have been impossible without the use of these screens. VFX courses help students learn the chroma key technology and its usage one by one and in steps to be used better. You will find that it would be impossible to complete any film without this technology.
It is also essential to understand that visual effects depend all upon the editing of chroma key. When you replace the green and blue parts of the pictures with the pictures you need it makes the perfect shot. Now you might wonder why not just use one colored screen. Why use both green and blue screens. Green is the most distinct color and stands out in contrast to other colors as well.
That is one reason why mostly people use the green colored screens for movies and other videos. But ever wondered what the blue screen is there for. For your VFX courses in India the primary thing to learn would be the difference between these two color uses. Blue is used in places where there is green color in front of the screen. If you are shooting a scene in a forest or if the person is wearing green costumes then also blue screens are to be used.
It would be impossible to chroma key the green screen if the subject in front is also wearing the same color. Therefore, you must be aware of the different uses. Blue screens are used a lot many times in superhero movies. For example in the movie Green Lantern, the protagonist’s costume was green in color. This coordinated with the blue screen the best. There was no need for any kind of green screen what so ever.
