Sony Cyber-shot RX10 III - Manual (Page 145)

If you change [Gamma], the available ISO value range changes.
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 this case, perform custom setup with a gamma other than [ITU709(800%)] or [S-
Log2] first, and then reselect [ITU709(800%)] or [S-Log2] gamma.
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.
