For a "filmic look" when shooting with digital cameras. When using the Schneider Optics 4x5.650 Digicon Filters 1/4-2in front of the lens, it optically raises black levels while lowering highlights.
By compensating with in-camera gamma settings, a higher dynamic range can be recorded than the camera alone can achieve. The result is more detail in highlights and shadows with no effect on resolution and no color shift. Highlight areas remain clean and halo-free. May be used on a 35mm cine camera to approximate the look of a lower contrast film stock.
