##### Ring Light Illumination Values

The process for editing the Ring Light Illumination values is more involved than a Top or Bottom light. Additional controls are provided for Ring lights.

Changing the Ring Light Intensity – You can change the intensity of any lamp by selecting the needed Rings, Sectors, Bulbs or entire ring lamp depending on the "Ring Light Control Modes". Moving the slider bar or typing a percentage value in the % box will change the intensity of the active segments.

Absolute and Relative Controls – For Ring lamps, it is also possible to choose whether an increase or decrease of the bulb intensity should keep their relative differences (RELATIVE ), or should set them all to the same value (ABSOLUTE ).

- With the Absolute button selected, all of the active LEDs get the same intensity specified.

- With the Relative button selected, all of the active LEDs keep their relative differences, but all increase or decrease by a specified amount. For example, if the outer ring has intensity 30%, the middle ring 40%, and the inner ring 50% then sliding the slider up by 10% moves them to 40%, 50% and 60% respectively.

Switching a LED On or Off – You can easily switch a lamp on or off by clicking on the specific LEDs graphic in the tab (though not inside the Intensity circle). A red cross through a bulb indicates that the light is off. A highlighted and shaded bulb indicates that the light is on. The number of LEDs affected on a ring lamp depends on the current "Control Mode".

Turning on the Live View Overlay – If you are using ring lights, you can place a graphical overlay of the lamp to appear in the Live View tab of the Graphics Display window. This overlay allows you to set illumination values and switch bulbs on or off directly by clicking on controls in the overlay on the Graphics Display window. You can also control the display of this overlay by using the Ring Lamp icon in the Live View tab.

Click the Apply button to actually change the illumination values.
