Can the green curtain be dug without lights?

Of course. Green screen matting can provide enough contrast without illumination, which is convenient for later matting processing. Green screen matting is to isolate the subject from the background and only keep the subject, so the background must be pure green. If a high-quality green background is used, its color saturation is high and uniform.
