Chapter 5 Shooting — Image quality adjustment
It is recommended to shoot at 40% to 55% for face tone.
f
[V-504580L1]
This is the EVA-LOOK gamma curve with 14Stop latitude equivalent to [V-Log].
The rise is equivalent to approximately 5.0 times, and the gamma factor is 0.45, which means up to 80%.
This is a setting focused on soft texture. The color is not easily saturated up to upper limit of the latitude.
It is recommended to shoot at 40% to 60% for face tone.
f
[VIDEO]
This is the BroadCast-LOOK gamma curve with 600% dynamic range equivalent to the generally used video camera.
f
[HLG]
this is the hybrid log gamma curve with wide dynamic range of 1200%.
The color range equivalent to BT.2020 is automatically set.
