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.
You can now lean the joystick all the way up and down and the gain will never rise higher than
the limit you have set.
TIP When the coarse control is combined with the sensitivity control, you can define
an upper and lower limit to the gain control.
For example, imagine you want to limit the gain so it never rises above f4.0 because
gain above that level will clip highlights in your image. You also want to limit the gain so
its minimum setting will be f8.0 to maintain the optimum sharpness range for your lens.
To do this:
1 Increase the gain control to its maximum position by leaning the joystick all the way
to its top position.
2
Now decrease the coarse setting until it reaches the upper limit you want to set.
In this case, f4.0.
3 To set the lower limit, lean the joystick all the way to its bottom position.
4 Now increase the sensitivity setting until the gain reaches the lower limit you want
to set. In this case, f8.0.
Now you can lean the joystick all the way from top to bottom and the gain will stay
within the limits you have set. This is a powerful way to define your exposure limits,
plus gain finer control with the joystick due to allowing its maximum travel forwards
and backwards.
