Items of the picture profile
Black Level
Sets the black level. (–15 to +15)
Gamma
Selects a gamma curve.
Movie: Standard gamma curve for movies
Still: Standard gamma curve for still images
Cine1: Softens the contrast in dark parts and emphasizes gradation in bright parts to
produce a relaxed color movie. (equivalent to HG4609G33)
Cine2: Similar to [Cine1] but optimized for editing with up to 100% video signal. (equivalent
to HG4600G30)
ITU709: Gamma curve that corresponds to ITU709.
ITU709(800%): Gamma curve for confirming scenes on the assumption of shooting using [S-
Log2].
S-Log2: Gamma curve for [S-Log2]. This setting is based on the assumption that the picture
will be processed after shooting.
Black Gamma
Corrects gamma in low intensity areas.
Range: Selects the correcting range. (Wide / Middle / Narrow)
Level: Sets the correcting level. (-7 (maximum black compression) to +7 (maximum black
stretch))
Knee
Sets knee point and slope for video signal compression to prevent over-exposure by limiting
signals in high intensity areas of the subject to the dynamic range of your camera.
