When referring to the positioning of objects and talent in a frame, Camera Left refers to the left side of the frame as seen through the lens of the camera. That’s often the same direction as the right side of the on screen talent. Camera Right is obviously the right side of the frame. Similarly in post, Screen Left refers to the left side of the screen; Screen Right, the right side. These terms are extremely significant for post-production notes, since incorrect specification could result in tens of thousands of dollars of wasted work.
