505-5. Expressing the gradation of a picture (Knee, Gamma)Due to bright sunny weather or lighting, “blown-out highlights” can sometimes occur, where brightareas look completely white. This is a phenomenon caused by the luminance signals that are outof the camera’s Dynamic Range (processing range). In order to put such high-brightness inputsignals within the Dynamic Range, Knee function can be used to compress the gradation.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: Do not use Knee controls.[KNEE MASTER POINT] 80.0 - - - 93.0 - - - 107.0Sets the position of Knee Point.
