Reproducibility of high luminance areas
You can select the dynamic range from among
325%, 460%, and 800%. Selecting a wide
dynamic range, such as 800%, enables
reproduction of gradation at high luminance.
However, the brightness of intermediate
gradation will be lowered.
White limit
You can select either 109% or 100% for the
maximum value of video output (white limit).
While reproduction up to 109% is possible with
SDI outputs, only 100% may be available,
depending on the environment of the production
system. In such conditions, select 100% as the
white limit.
Midtone
You can select two values for the brightness of
intermediate gradation areas around skin tones.
Selecting a curve for bright intermediate
gradation may slightly inhibit reproducibility of
the high luminance.
To select HyperGamma
1
Select HYPER GAMMA on the first
line of TABLE on the <GAMMA> page
and select the hyper gamma curve most
suitable to the shooting conditions and
purpose on the second line.
2
Observing the output video level for a
gray card of 18% reflection rate on a
waveform monitor, adjust the iris so
that the level becomes equal to that
shown in the "Video output with 18%
gray card" column of the "Available
Hyper Gamma choices" table. (The iris
setting in this condition is the standard
iris setting for the selected hyper
gamma.)

Selecting the Gamma
Notes
• When this unit is in Custom mode (see page 43),
white clip level adjustment is allowed, but the
white limit values shown in the "Available Hyper
Gamma choices" table may not be obtained if you
adjust the white clip level.
• With a Hyper Gamma selected, the knee and
gamma level adjustments are not allowed, even in
Custom mode.

Using S-LOG
You can select "S-LOG A" (Sony-Log) on
TABLE and SPECIAL on the <GAMMA> page.
Sony Log (called "S-Log" below) is a gamma
function optimized for CCD cameras. It was
developed for use in the DI (digital intermediate)
workflow of film production, in which the camera
negative captured on film is digitally processed to
create the digital master release print.
