You can copy the settings of the picture profile to another picture profile number.

To Reset the picture profile to the default setting
You can reset the picture profile to the default setting. You cannot reset all picture profile settings at once.
MENU → (Camera Settings1) → [Picture Profile] → [Reset].
Note
Since the parameters are shared for movie and still images, adjust the value when you change the shooting mode.
If you develop RAW images with shooting settings, the following settings are not reflected:
Black Level
Black Gamma
Knee
Color Depth
When the [ Record Setting] is [120p 100M]/[100p 100M] or [120p 60M]/[100p 60M], [Black Gamma] is fixed at "0" and cannot
be adjusted.
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 or S-Log3 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 or S-Log3.
Setting [ITU709(800%)], [S-Log2] or [S-Log3] may cause an error in the white balance custom setup. In this case, perform
custom setup with a gamma other than [ITU709(800%)], [S-Log2], or [S-Log3] first, and then reselect [ITU709(800%)], [S-Log2],
or [S-Log3] gamma.
Setting [ITU709(800%)], [S-Log2] or [S-Log3] disables the [Black Level] setting.
If you set [Slope] to +5 in [Manual Set] under [Knee], [Knee] is set to [Off].
S-Gamut, S-Gamut3.Cine, and S-Gamut3 are color spaces exclusive to Sony. However, this camera's S-Gamut setting does not
support the whole S-Gamut color space; it is a setting to achieve a color reproduction equivalent to S-Gamut.
