Sony ILCE-7S - Manual (Page 129)

Note
Since the parameters are shared for movie and still images, adjust the value when you
change the shooting mode.
If you print RAW images with shooting settings, the following settings are not reflected.
Black Level
Black Gamma
Knee
Color Depth
If you change [Gamma], the available ISO value range changes.
There may be more noise in dark parts depending on the gamma settings. It may improve
by setting the lens compensation to [Off].
When using S-Log2 gamma, the noise becomes more noticeable compared to when
using other gammas. If the noise still is significant even after processing pictures, it may
be improved by shooting with a brighter setting. However, the dynamic range becomes
narrower accordingly when you shoot with a brighter setting. We recommend checking the
picture in advance by test shooting when using S-log2.
Setting [ITU709(800%)] or [S-Log2] may cause an error in the white balance custom
setup. In that case, set the exposure bright first and then perform custom setup.
Setting [ITU709(800%)] or [S-Log2] disables the [Black Level] setting.
If you set [Slope] to +5 in [Manual Set], [Knee] is set to [Off].
S-Gamut is a color space unique to Sony that provides a wide color space equivalent to
film cameras. However, S-Gamut setting of this camera does not support the whole color
space of S-Gamut; it is a setting to realize a color reproduction equivalent to S-Gamut.
