P.1 Green Screening

Green Screening

It removes a specific range of colours from a video making them transparent.
The colour green it is used because its the least used colour therefore its the safest.
It is useful for when you want to film in a location such as paris but you can't get there, for example in Paris. So it is used to get rid of background but also to use some background without being there. This also saves time and a lot of money.

Green screening is mostly used in weather forecast broadcast as it would be impossible to get that background.
Green creeping was mainly used so you can put two images together at the same time.
Blue was also used along with the green. So they would have a blue screen but the problem was that if there was a man standing in front of the blue screen with a blue suit, when you go to premiere pro or after effects and change the background to for example a dessert island, the suit of the man will change as well which isn't what you want therefore it proves that green is the safest colour for this.

Also a common mistake in green screen is shadow. You might have someone standing in front of the screen and get its shadow on the background which won't let you work with it afterwards.
Green screening is not only used in videos but it is also used for pictures, which is how some of the pictures in magazines are made.


The first film ever made to use green screen was "Four heads" the down side to this was that they used a green matt to create he illusion therefore the matt couldnt be moved at all.
Green screening is also used in Ugly Betty which allos them to make the scenario to look however they want it to.

As well as the green screen there was first the blue screen, which was created in the 1930's by RKO Radio Pictures, and was used to create the effect of (wipes) which was give the effect of window wipers on cars. It has been 83 years since the birth of the blue screen which has evolved into the green screen which allows more colours to show up easier.
