Let The Use Of Chroma Keying In Green Screen Process Improve Frames
Many people use of chroma keying in green screen process for many different reasons. It has its place in image placement in photography and when films are edited to put characters, objects and scenes where they would not be. To show you how this is done I have included examples in this article to give you a better understanding.
Chroma keying is not the only name that this kind of programming is known by. It is also known as colour keying for a very good reason. This is that you put two screens together, the one being the green screen, and then to the screen you can add pictures or people to the front or back of the frame or picture.
An example of this is where people use a green or in some cases a blue screen on weather reports so that a person can stand in front and point to the relevant images without looking out of place. It is also used in films where both people and animation are to be present at the same time.
This is great for putting a person or character on the moon or in the sun without them actually having to go there. You can put characters into a film that have never set foot on the set and all that is needed is clever lighting, a computer and a green backdrop.
To make the programming both understandable to those who are applying the pictures or frames as well as the computer. The way this is done is through certain codes. There is a code for each pixel and these can be represented by letters, by numbers or maybe all of them. There are also different codes used for referring to the green screen or whether you are referring to the image in front or behind
Different references are used by different programmes which is why I could only give an example. You can alter the references with some programmes and of course if you know what you are doing. To alter the images you should be aware that it is only with these designated codes that changes can be made. This is made easier with certain programmes.
As film once used so predominantly in photography is used less and less in favour of digital the green backdrop is used more than the blue one. This is because it gives you a much clearer image allowing better graphics whether the image placement is used in gaming, the latest film or even advertising. If it is necissary for the colour green to be either worn by a person or the image you want to merge the colours will clash, so you do not get the desired result. In this case you should use a blue or red screen.
