How to prepare the green screen
Click the green area for fullscreen and fill the camera frame with green. Reduce reflections and keep the subject away from the display when possible to limit spill and shadows. For a monitor check inspect the center edges and corners, compare red and blue fields, and press Esc when finished.
Green screen filming tips
For a cleaner green screen background, keep the field evenly lit, avoid green clothing that matches the background, and reduce reflections. Check the full frame before filming, then adjust distance and brightness for the camera exposure and white balance used in post production.
