Vaxis VFX 4x5.65" Rainbow Dazzle Filter

The Rainbow Dazzle filter takes any bright point source in frame, a practical bulb, a sun hit, a specular reflection, and breaks it into a scatter of small rainbow-colored flare bursts, a more chaotic and colorful cousin of a standard star filter.

It drops into a standard 4x5.65 inch matte box tray, so it swaps in and out alongside a production's other drop-in glass without changing the rest of the filter stack.
