The green screen or “Chroma key technology” is a filmmaker’s best friend. It helps make the not possible possible. Need to recreate World War II Hiroshima? Want a computer generated personality to share the screen with a real life actor? Do you need to shift backgrounds for dramatic effects? All of these things can be done with the aid of green screen Hollywood technology. However , this great film making tool looks to be available only to enormous flats that produce smash hit flicks. It doesn’t appear like something at the reach of, say, an independent filmmaker or struggling film scholars. This problem can be solved now by creating a customised chroma key technology screen. With a customised screen, there is now no need to shell out a lot of money for screen studio rentals.
