Selecting the Gamma
Chapter 3 Basic Adjustments and Settings
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.)
• When the camera is in Custom mode (see page 30),
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.
