Iris and Master Black Active
Once your levels are set and you want to lock them so they are not accidentally changed,
press the 'iris/MB active' button. This enables a lock on the gain and master black so that any
accidental movements of the joystick will not affect your settings. The 'Iris/MB active' button
label will illuminate red when the lock is active. To disable the lock, press the button again.
TIP You can lock the black/pedestal level independently by disabling the 'master
black' option in the 'settings' menu. When disabling master black, the black level is
locked but the iris/gain level can still be adjusted. Don't forget to enable the master
black setting if you want to make changes to the black/pedestal level.
Auto Iris
If your camera is using a compatible lens with electronic iris control via the camera, then you
can press the 'auto iris' button for a quick automatic exposure setting. The camera will set
exposure based on average brightness, providing an average exposure that is a balance
between the brightest highlights and the darkest shadows.
Call
Holding down the 'call' button will flash the tally light on the CCU's selected camera. This is a
helpful way of seeking the camera operators' attention, or to let your operators know you are
about to go live.
While holding down the call button, the large camera number next to the joystick will also flash
so you can visually confirm the call is being sent.
Panel Active
After you are happy with your camera settings, you may want to lock all the controls so they
cannot be accidentally adjusted. Pressing the 'panel active' button enables the CCU lock so all
controls cannot be changed. Press the button again to disable the CCU lock. This can be a
helpful feature when you are recording a locked off shot and don't want the setting adjusted by
accident, for example a wide shot of a stadium filling as the crowd enters.
ATEM Camera Control Panel is an exciting, practical and efficient way to control
Blackmagic Design cameras in your live production. We believe you will enjoy the experience
of hands on camera control using CCUs, which lets you take control of exposure and other
camera settings, freeing up your camera operators so they can concentrate on framing
and focus.
