Blog 11: Green Screen

In order to create a green screen you would have to have a solid back drop. Most places that use green screens like when doing the news use blue or green as a back drop. What happens is they do is use chroma key either in the background or in front of the person or both and replace the back drop with this image. Green is the best option because when using cameras it will give a better image. You have to have good lighting or you will have shadows. I think the my favorite movie that uses green screens is Harry Potter. Below is a clip for Harry Potter showing the several scenes in which green screen is used. It is kind of amazing how it is used if you have seen the actual movie you would be shocked they used green screen imaging. Well I guess I am I never really thought much about it. But this blog kind of opened my eyes I don't think I will ever be able to watch a movie the same.
