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.

How does GPS work?

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.

How to find the information you need from Google?

 Google, the world's most popular search engine, may not be able to find Internet users who do not search for information at least once a day. If we search by typing just a word or two, the huge store of information that is caught in front of us, may not have an alternative to initially collecting information. But sometimes we have to get a lot of speed to find the necessary information from Google. Our hair falls out to find the desired information, especially in the case of academic research. But it is possible to get all the information we catch from Google. So if we pay attention to some things in the case of Google search, we can easily find the site of our choice or the necessary information, so we will save a lot of time. According to a survey by Whistler University, only 25 percent of students can find the information they need from Google. In our country that number may be less. Despite having this huge database at hand, we are not able to use it properly. Here are some us
