We all know that movie and TV producers use visual effects (VFX), but you’ll be shocked to realize how extensively they are used in movies!
Green-screens are not always green, they can often be blue, and they can technically be of any color as long as this color is not being worn by any of the actors.
When these scenes are recorded, the green-screen color is digitally selected and made transparent by special software. (If the color selected was also being worn by the actors, they would appear to have holes through them!)
The following set of before-and-after photos will show you how much your favorite shows and movies rely on the magic of VFX.
