Important Chroma Key Green Screen or Blue Screen Tips
- The secret to creating an easy to use chroma key background is to
use soft lighting. Soft lighting produces near shadowless light.
Shadows on a green screen or blue screen will make it more difficult to
replace the background (with your photo or video) as the light levels
will not be even. Soft lighting can be produced by using diffusion gel
filters on light source, bouncing the light source or using fluorescent
lighting. - Chroma Key Background / Backdrop must have even, seamless
lighting across the entire area. No hot spots or dark areas. Check
with a light meter or the auto exposure on your camera. - An important chroma key tip is to not have wrinkles in the
green screen or blue screen fabric or backdrop. Stretch the chroma key
backdrop tight. - Use separate set of lights just for lighting the chroma key
background. Another set of lights should be used to light your subject.
Three point lighting: Key, Fill, Back-light should be utilized when
lighting your subject / product. - Distance is your friend. Move your subject as far away from
the green screen as possible. 4ft would be a recommended minimum
distance. As your subject is closer to green screen it creates two
problems: A) a Shadow, B) Green light bounce back on to your subject
which will then make it difficult to create a clean matte.
