  • Page 11: Spill Suppression

    Spill suppression After setting proper matte the next step is a process called spill suppression. The slider which is used mostly on this step is DeSpill Coarse. Below 500 it will only affect the parts where colour has similar tone as background colour (greenish or bluish). Over 500 it starts slowly to affect more and more parts where background colour is not dominant anymore.
