Good to know
Green screen on a display
For small objects, a monitor can serve as a green screen. Make sure the object does not reflect and lower the brightness so no green glow spills onto the subject.
Which green?
We use pure RGB green (#00FF00). For camera keying, a slightly darker chroma green is sometimes easier; you can set it with the color picker.
