Below are the main reasons for using Green Screen in VFX.


Why is green screen used?


You may know that VFX movies use a lot of graphics. Which requires the removal of the background (Chrome Key). And the green color of the green screen is different from other colors that we see. For example, the color of any part of our body but not green.


This allows the color of the face, hair, ears or parts of the cloth to be easily removed from the background. And as a result, graphics can be done easily.

Why is the train engine always kept running?

How did the word 'Wi-Fi' originate?

 In 1997, an organization called the Wireless Ethernet Compatibility Alliance (WECA) introduced Wi-Fi, which was renamed the Wi-Fi Alliance in 2002. This time around, the Wi-Fi complies with the IEEE 802.11b [2] standard, but they wanted a more interesting name instead of the IEEE 802.11b name. Phil Belanger, one of the members of the Wi-Fi Alliance, says the reason for the naming is as follows: The word Wi-Fi has no meaning.
