To get information about the current lighting solution, you can use the Lighting Analysis tool. The scene must include a lighting solution before this tool is available. You can access this tool by selecting the Rendering Advanced Lighting Lighting Analysis menu command. This opens the Lighting Analysis dialog box, shown in Figure 28.16.

Figure 28.16: The Lighting Analysis dialog box displays the light values at the specified location.

From the Quantity drop-down list, you can select to view light values for Illuminance and Luminance. The cursor also changes into an eyedropper while the dialog box is open. Clicking with the eyedropper in one of the viewports displays the lighting values for that point in the Lighting Analysis dialog box.
