Gamma Display Assist
Movies with S-Log gamma are assumed to be processed after shooting in order to make use of the wide dynamic range.
Images with the HLG gamma are assumed to be displayed on HDR-compatible monitors. They are therefore displayed
in low contrast during shooting, and may be difficult to monitor. However, you can use the [Gamma Display Assist]
function to reproduce contrast equivalent to that of normal gamma. In addition, [Gamma Display Assist] can also be
applied when playing back movies on the camera's monitor/viewfinder.
