Gain and Pedestal Level Control
The joystick control lets you make fine adjustments to the gain/iris and pedestal/master
black levels.
Leaning the joystick forwards or backwards opens or closes the camera’s iris, also known as
the gain level. As you lean the joystick forwards and backwards, its indicator strip will illuminate,
providing an approximate display of the camera’s exposure. For a precise assessment of the
exposure f-stop, observe the iris indicator.
The joystick lets you adjust
the gain level by leaning
the controller forwards and
backwards. The master black
level can be adjusted by turning
the ring wheel clockwise or
counter clockwise. Corresponding
indicators are provided for
accurate measurement.
Located around the collar of the joystick’s handle is a ring wheel that controls the pedestal
level. The ring wheel has small ridges built in for firm control and a position indicator is located
on the top of the knob to show the physical positioning of the wheel. Turn the wheel clockwise
to increase the master black level, or counter clockwise to decrease.
Iris and Master Black Indicators
The indicators for the iris and master black joystick control displays the gain value, shown as the
f-stop exposure level for the camera lens and the level of the master black setting.
Sensitivity
The sensitivity setting lets you define a specific range between the highest and lowest gain
levels so you can achieve finer control using the joystick. For example, when sensitivity is at its
maximum setting, you can lean the joystick all the way forwards or backwards, however it will
only affect a narrow range of gain.
You can define how narrow the range is by increasing or decreasing the sensitivity.
Coarse Control Knob
The coarse setting lets you define a limit to the maximum gain control. For example, you may
want to ensure your gain never rises higher than a determined exposure.
To do this:
1 Lean the joystick to its highest position to increase the gain setting to its maximum.
2 Now decrease the coarse setting by rotating the coarse knob counter clockwise until
the gain reaches the limit you want to set.
