a target light, the target distance remains fixed, no
matter how far you dolly.
Dollying a light
When you dolly a light, the light source moves
closer to and away from its target. Because
spotlights have conical beams, dollying a spotlight
closer to its target shrinks the area illuminated at
the t arget. Similarly, dollying a sp otlig ht away from
its target expands the area illuminated at the target.
The three buttons of the Dolly Light flyout are
available when a target light viewpor t is act ive.
When a free light viewport is active, the button

for this type of light. If you activate a target light
viewport, the three buttons are again available.
