Prior to the photography even commences, the initial question is often “which color – green or blue?” You have to pick a non-competing color for the green or blue backing. Do not attempt to shoot blue objects on a blue-colored screen. This often requires coordination with the outfit department. A few believe that a number of skin color appear far better on blue-colored screen or that blonde hair does not do well on green screens. Modern digital keys generally render these issues obsolete.
Both green screens as well as blue screens require a great deal of light, and lighting is costly. One benefit of a green screen is that it is a lot easier to light simply because tungsten lights make a lot more green light than blue light. One disadvantage of a blue screen is that the blue record of both movie as well as video has probably the most grain or noise. This severely has effects on the matte in compositing, giving it sizzling edges. All other issues being the same, this makes green the most preferred backing color.
The essential thing to remember is that the overall aim isn’t to make the very best looking green screen shot, but to make the best green screen composite. Many times, the hard work will be in lighting and composing the talent with scant consideration given to the green screen itself. The talent can always be color corrected during compositing, yet the compositor is bound to the green screen as it was shot.
An LA green screen studio is lit totally separately from the talent. The truth is, the lights for the talent are turned off while lighting the green screen. It is lit within half a stop of uniformity left, right, top and bottom and approximately one stop lower than the key light. If it is too bright, it will lose saturation as well as throws a lot of spill light in the talent. Too dark and there’s insufficient luminance as well as chroma for a good key and it adds dark edges to the composite. The exception happens when shooting on a cyclorama since both the green backing and the talent are unavoidably lit by the very same lighting.
The biggest challenge when setting up a green screen is even lighting. You have to prevent any chance of a shadow since it is a darker color to the camera and may not register. You must have as narrow a color range as possible in chroma keying. To the right, you could see those shadows and just how they emerge to be darker shades of green. It’s something that ought to be prevented. Professional green screens have exclusive lights known as kino flo lights which give the green color a bump in order to get rid of any of the other areas of the visual array.
When shooting LA green screen studio on film, there are some points to keep in mind. The first is to make use of the best grained film stock possible. Fast film stocks with large grain can make for chattering mattes at compositing time. Also, never ever place filters on the camera lens. Any filters will be subtracting light which the compositor needs to come up with a great matte. Filter effects can be incorporated at compositing time.
