- When deciding to use a green or blue screen, choose whichever color occurs least in your foreground: if your talent is wearing blue jeans, shoot on a green screen; if they’ve got green eyes, use blue.
- Consider lighting: as the action plays, light the screen evenly to make for a clean extraction. Pay attention to how shadows move, and set your lights to avoid shadowing on the screen.
- If the camera is moving, attach tracking markers to the screen itself so you can extract the camera motion and then use that same motion on whatever you’re putting into the scene.
- If something in a shot will need to be tracked later, provide enough tracking points (at least a few objects with sharp corners, like a table) in the foreground.
- Don’t assume automatic sharpening of the images on the camera will give the sharpest, crispest picture -
this camera feature can create problems with doing green screen extractions along the edges. ‘Turn the sharpening off on the camera if you’re going to do that, and if it needs to be sharpened after the extraction work has been done, that can always be added in the post process,’ says Kramer.
