Why is a green screen used for VFX in the background?

 

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.


Those of us who have seen Hollywood movies at least once in our lives must be familiar with VFX. The Titanic movie was shot in front of a green screen in a room, not in the ocean. Can't believe it? But look at the picture below.

One of the unique gifts of modern technology is GPS (Global Positioning System). Nowadays, anyone who has a smartphone with GPS can travel around the world without any help and all this is possible for GPS technology. GPS (Global Positioning System) was developed in 1955. Since then, over time, its technology has improved in many ways. You have a mobile in your hand and you can get all the information including your location in a blink of an eye but all these things are possible for the satellites above your head. GPS takes the help of satellite technology to know your location. There are currently 30 (More than 30 according to NASA) satellites orbiting the Earth for GPS work, of which 27 are currently in operation and the remaining 4 (appx.) Are for future backup. If any of those 30 satellites are malfunctioned, then those 4 satellites will be used. The three parts of GPS are: 1. Satellite 2. Ground Station 3.

Why are the letters on the computer or mobile keyboard arranged in reverse?

One of the things we often do nowadays, especially in modern times, is typing on the keyboard. What we mean by typing is writing on computer, mobile. But even before mobile, computer, the type of device that people have typed or typed is "Typewriter". Now, if you look at typewriters you will notice that most typewriters are not arranged in ABCD format at all, which is exactly the same as the current keyboard.

Now if I say that the birth of QWERTY keyboard is designed to reduce the typing speed of the keyboard, what will happen? When the typewriter was first arranged in English alphabetical order, people typed on the keyboard so fast that the 'keys' or 'buttons' on the keyboard would get jammed.
