Gamma (NOT valid for HDR)
Gamma correction
To compensate for the non-linear response of display devices, a gamma correction is
applied to the video signal. The gamma correction adjusts the tonal response of the
standard transfer curve.
Gamma curve
The gamma curve defines the distribution of tonal values. The following standard gamma
curves are available: ITU709 (default), BBC04, BBC05 and BBC06, ARD, Gamma-J and
Gamma-S.
In the camera menu, navigate to the Production Setup > Levels > Gamma > Curve item
and select the Gamma curve you want to use.
Gamma presets
The Gamma preset selection determines how mid-range tonal values are reproduced.
Available gamma presets are:
• Nom (nominal) setting: Master Gamma = 76 (slope = 0.45)
• Lin (linear) setting: Master Gamma = 0 (slope = 1.00)
• Var (variable) setting: Master Gamma is adjustable between 0 (slope = 1.00) and 99
(slope = 0.35).
In the camera menu, navigate to the Production Setup > Levels > Gamma > Preset
function and select the Gamma preset from the list.
