Portrait diffusion filter

The Schneider 4 x 5.65" Radiant Black 1 filter is a professional cinema accessory designed for matte-box workflows. It softens skin tones and lifts shadow detail while preserving deep blacks, giving digital footage an analog film aesthetic. The strength 1 density provides a noticeable yet controllable halation effect suited to narrative and commercial portrait work.

Colored sparkle diffusion

Tiny colored particles embedded in the glass create subtle sparkle highlights that mimic vintage lens characteristics. This optical design reduces digital harshness and adds a nostalgic "back-to-the-90s" mood without degrading overall image sharpness. Cinematographer Matthias Bolliger used this filter on a feature film to achieve that specific period look.

4 x 5.65" matte-box format

The rectangular 4 by 5.65 inch dimensions match industry-standard matte boxes, allowing quick insertion alongside ND or polarizing filters. No screw-in thread is present on this model, so it requires a compatible filter tray or holder. The same Radiant Black series also exists in 6.6x6.6" panels and M77, M82, M95 circular mounts for other rig configurations.

Questions about this item

Will the 4 x 5.65 inch Radiant Black 1 filter need any special cleaning or replacement over time?

Standard optical glass care applies; wipe with a lens cloth and fluid, and store in the supplied pouch to avoid scratches that would degrade the diffusion effect.

What is the first limitation you hit when using this strength-1 filter continuously on a cinema camera?

The fixed 1-strength diffusion cannot be dialled back, so scenes needing sharper contrast require swapping to a lighter grade or removing the filter entirely.

Does the 4 x 5.65 inch Radiant Black 1 filter add noticeable heat or power draw during all-day shoots?

No; it is passive glass with no electronics, so it adds zero power draw and no measurable heat to the camera system.
