How do I ultrakey only part of the frame
Gday.
I am using a ‘greenscreen’ by having a photoshop page open on a large monitor in the background of my shot.
However, the Cintiq in front of the monitor reflects the green from the monitor so that when ultrakey is applied it also selects the reflection in the Cintiq screen.
How can I apportion only part of the screen to ultrakey?
Is this possible?
Thanks.
