f [V-Log]:
This is a gamma curve for gradation and wide latitude (exposure range). A grading process after recording is required.
f [V-709]:
This is a gamma curve equivalent to Varicam standard CINE-LIKE. A tone optimum for preview on the monitor can be achieved.
f [V-406060]:
This is the VARICAM-LOOK gamma curve with 14+Stop latitude equivalent to V-Log.
The rise is equivalent to 4.0 times, and the gamma factor is 0.60, which means up to 60%.
This is a setting focused on contrast. The color is not easily saturated up to upper limit of the latitude.
It is recommended to record the face tone at 40% to 55%.
f [V-452080], [V-452080L]:
This is the VARICAM-LOOK gamma curve with 14+Stop latitude equivalent to V-Log.
The rise is equivalent to 4.5 times, and the gamma factor is 0.20, 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 record the face tone at 40% to 60%.
The color saturation of area with input is approximately 1.7 to 3 Stop is enhanced against the gamma curve up to software version 11.93-00-0.00.
To use the gamma curve with color saturation up to software version 11.93-00-0.00, select [V-452080L].
f [VIDEO45]:
This is the BC-LOOK gamma curve with 600% dynamic range equivalent to the generally used video camera.
It means gamma factor 0.45.
f [VIDEO50]:
This is the BC-LOOK gamma curve with 600% dynamic range equivalent to the generally used video camera.
It means gamma factor 0.50.
This is a design focused on contrast.
