I was recently listening Team Deakins podcast with Robert Eggers & Jarin Blaschke - LINK and at 56:30 Roger asks Jarin "What stop were you lighting to" to which Jarin replies "I rated that whole movie at 80"
Does this mean he exposed the skintones (or main subjects) in the frame at 80IRE or does it mean something completely different. Any explanation would be helpful, thanks ?
