If you are using fabric and it’s wrinkled, steam or iron the fabric until it’s smooth again. If the fabric is still bunching, stretch it out more tightly to eliminate the creases. If you are using paint, check for areas that are chipped or scuffed and repaint them. If there are a lot of chipped or scuffed areas, you should repaint the entire surface to ensure evenness of color.
File formats that compress your image less, such as RAW or ProRes, are larger in file size but preserve all the small details of your video file, giving you a higher-quality image. [3] X Research source
If your screen is particularly large and the lights on the side can’t reach all of it, place an additional two lights at the bottom of the green screen pointing up. [6] X Research source Every green screen is different, however, so start with this basic setup and move the lights as necessary to adjust.
You can add more lights if necessary, but using too many lights increases the amount being reflected back, or spilling, onto your subject. This will make it harder to separate your subject from the green screen in editing. [8] X Research source
If your subject is standing on part of the green screen, place a differently colored mat underneath them to prevent light bouncing up at them. [10] X Research source
Do not light your green screen and subject at the same time. Light your subject separately to reduce shadows and light spilling. [12] X Research source
The fill light is meant to diffuse the key light, so it should be softer than the key light. Lower the intensity of the fill light, or tape a diffuser such as wax paper over the lens to soften the effect. [14] X Research source
Using a waveform monitor is more accurate than simply looking at the camera monitor. If you do not have a waveform monitor, you can download a smartphone app such as Cine Meter or Green Screener. These apps can check the evenness and exposure of your lighting. [17] X Research source
You don’t want to lower your ISO too much, as this may underexpose your green screen. Experiment with your camera’s ISO settings while making sure that it isn’t making the picture too dark.
