The AG-CX350 Book: Understanding scene file operation 795-4. Expressing the gradation of an image (Knee, Gamma)5-4-1. KNEE controlDue to bright sunny weather or lighting, “blown-out highlights” can sometimes occur, where brightareas look completely white with little to no detail visible. This is a phenomenon caused by theluminance signals that are out of the camera’s Dynamic Range (processing range). In order toput such high-brightness input signals within the camera’s Dynamic Range, Knee function can beused to compress the gradations.MENU > SCENE FILE > (Factory default settings underlined)[KNEE MODE] AUTO / MANUAL / OFFAUTO: Adjusts master point and slope automatically.MANUAL: Knee master point and slope can be adjusted manually.OFF: Knee mode not used.[KNEE MASTER POINT] 80.0 - - - 93.0 - - - 107.0Sets the position of Knee Point.
