CONTROL allows you to manipulate a light’s attributes. Attributes are organized into families of Intensity , Color , Position and Shape . Only those attributes supported by the selected light are shown. If lights with differing attributes are selected, the tools available are determined by the first light selected. At least one light must be selected to activate CONTROL.
When you select a Light and go to CONTROL | WHEELS, there are four (or less) ‘bubbles’ to show you the Yellow, Red, Green and Blue wheels are controlling. In the center of the screen is a mimic of what the light is doing similar to the ones in SELECT:
This shows the Intensity as a number and graphically as ring, it shows what attribute families have recently changes with the four attribute family ghost icons , it shows the color of the Light, where the Light is pointed and any shutter cuts that may be set. If you have multiple Lights selected, the mimic shows the state of the first Light in the selection set. There are also Fanning, Flip and Highlight and Lowlight tools that appear to the left and right of the mimic.
