Petro Vlahos Blue Screen Difference Fusion 5.2

First a credit to the original video interview:    • The Masters of Compositing Series - Petro ...   This video will go over Petro Vlahos 1959 Blue Screen Mask difference which was used for over 40 years until the early 1990's for Film compositing of Blue Chroma key screen. From sections of the interview to a chart showing the steps to a demonstration of this inside Eyeon Fusion 5.2 ( it's old but fine for showing the steps). Thanks for watching these videos, and to Petro Vlahos for his contribution to the Compositing tools we all use today.
