Green Screen Lighting

If you keep finding that your green screen shoots are not as clean as they should be, the problem may be your lighting. While each chroma-keying system has its own tolerances, the general consensus is that the green (or blue) background must be lit as evenly as possible. Wrinkles, if it is a cloth / temporary background, or seams & uneven paint, if it is a hard / permanent background, should be minimized to help reduce keying problems. The preferred methods involve being able to light the background and the subject separately. If you light them together you will likely see green reflected on your subject from behind after you have Chroma keyed out the background. If your subject is human and framed waist-up or looser, this can require between six and twelve feet between your subject and the background. With tight framing it may be possible to evenly light the background with just one broad source. Typically two or more lights are used to light the green screen. A single light can at times be used like a single Omni-light, floor-mounted on a Big-foot & Scissor mount, fitted with a 300W lamp for example. Light your subject separately with 2 soft boxes or one soft box and a reflector panel. then from the side or above the screen throw a back light on your subject. a little amber sheet on this light is nice. Using this lighting method you will make your editing easy and clean. Visit Our Website.
