In this tutorial, I explain how to properly light a green screen. Properly lighting a green screen greatly helps create a more professional look and make it much simpler to chroma key the background out in editing. It also helps to simplify the color correction process. There are two major factors in proper green screen techniques and no amount of light is ever too much. The two most important factors are to:
1 - Start with the smoothest surface possible. Stretch out the fabric of the green screen to ensure that there are no wrinkles. Wrinkles make shadows and shadows are no good!
2 - Distribute the light evenly. I believe this is done with a 3+ light setup. One light should be the main light, used to light your subject and partially light the green screen. The second light should be used specifically to light your green screen. I like to place it at a roughly 15 degree angle to the surface of the green screen and splash the light evenly over as much of the surface as possible. Lastly, I like to have a backlight. This helps in two ways. One is to aid in distributing the light on the background and it also helps to eliminate that pesky green halo that often appears around a subject.
There are certainly finer points to green screening, but these basic principles will go a long way to ensuring you have a pain free chroma keying experience.
For those that have asked, here is a link to my current green screen kit. It's not pro grade, but it is an excellent starting kit and an excellent kit for YouTubers.
