Green screens can be made from solid-color, bright green fabric, or solid materials, such as cardboard, or plywood, painted solid green. If you have a dedicated studio space, creating a dedicated green screen wall, by painting a flat wall, is an excellent way to achieve this effect.
Fabric green screens can be created by finding material to make a specially designed cover to be stretched over an adjustable frame. Choose fabric that is bright, and solid, with no pattern, or variations in the coloring. Look at the fabric closely to ensure that the finish is not reflective, which can cast brighter “hot spots” when illuminated. Fabric should be fairly heavy, and a poly blend that is wrinkle-free works best. If painting the material, use a paint roller to roll bright green, flat paint on the whole surface of your sheet.
Hang your screen from any convenient wall, using thumbtacks or clothespins to secure it along the top edge. If light stands are available, set two to the height required and attach a boom pole, or other stout pole, between them, using grip heads. Allow the bottom of the fabric to drape out, creating a slight curve up at the bottom. Use sandbags, or other heavy items to hold the corners down.
Another option is to use heavy duty cardboard or plywood to create a solid green screen. If using cardboard, paint both faces to prevent warping. Fasten the screen to a wall with thumbtacks, screws or nails.
