The Lightflex tool emulates the flashing of light in the film box. It flashes the image with a base illumination. This has the effect of lowering the contrast of the scene that the camera photographs.

The actual Lightflex device was used by cinematographer Freddie Francis to create a film-within-the-film look in The French Lieutenant’s Woman, and again to create the color look of Dune.
