Double Net: two-ply bobbin net diffuser mounted at 45° angle, reduces light intensity approximately 70% with minimal scatter loss.

Technical Details

Double Nets use bobbinet fabric with a mesh size of 1/8" per layer, with the second layer mounted rotated by 45°. This construction produces a transmission of approximately 30% of the original light. Available frame sizes range from 6"x6" for accent lighting to 20"x20" for area lighting. Modern variants utilize fire-retardant materials according to DIN 4102-B1 and weigh approximately 280 grams in a 12"x12" size. Attachment is via standard grip heads or C-stand arms.

History & Development

Double Nets originated in Hollywood in the 1940s as an evolution of Single Nets, after cinematographers like Gregg Toland required stronger light diffusion without scattering loss. Mole-Richardson introduced the first commercial series in 1952. In the 1960s, the 45° rotation of the second layer became standard to avoid moiré effects. Modern versions since the 1990s use synthetic fibers instead of silk and offer longer durability with continuous use.

Practical Use in Film

Double Nets are used when Single Nets are too weak, but scrims would interfere too much. Roger Deakins used them in "Blade Runner 2049" for subtle facial modeling in close-ups. Typical workflow: positioning 2-3 feet in front of the subject to avoid hard shadow edges. Advantage: preservation of light direction and quality with precise intensity control. Disadvantage: limited diffusion with very bright artificial light and potential moiré formation with fine textiles without correct rotation.

Comparison & Alternatives

Single Nets offer weaker diffusion with 0.6 stops, while silk materials also scatter light. Metal scrims diffuse more strongly (1.5-2 stops) but alter the light's characteristics. LED panels with continuous dimming are increasingly replacing mechanical solutions but offer less precise local control. ND filters on the lens diffuse globally, Double Nets selectively. For extreme diffusion, Double Nets are combined with Single Nets for a total reduction of 1.9 stops.

Perspectives

Cinematographer

Double Nets geben mir die perfekte Zwischenstufe zwischen Single Net und Scrim – ideal für Portraitlicht, wenn ich die Lichtführung beibehalten, aber die Intensität um gut eine Blende senken muss. Ich positioniere sie meist 18-24 Zoll vor dem Motiv, um weiche Übergänge zu erhalten, und achte auf die 45°-Rotation der zweiten Lage, damit keine Interferenzmuster im Bild entstehen.

Director

Für mich sind Double Nets ein subtiles Werkzeug zur Stimmungssteuerung – sie ermöglichen es, einzelne Gesichter oder Bildbereiche zurückzunehmen, ohne die gesamte Lichtdramaturgie zu ändern. Besonders bei emotionalen Wendepunkten kann ich so Charaktere visuell "dimmen" und ihre Präsenz in der Szene modulieren, ohne dass es dem Zuschauer bewusst auffällt.

Producer

Double Nets kosten etwa 85-120 Euro pro Stück und amortisieren sich schnell gegenüber zusätzlichen Lampenwechseln oder längeren Einrichtzeiten. Sie reduzieren Setup-Zeit um 10-15 Minuten pro Einstellung gegenüber Scrim-Wechseln und sind leichter als Metalllösungen, was Transportkosten spart. Wichtig: Ersatzbeschaffung einplanen, da das Netz-Material bei häufigem Gebrauch alle 2-3 Produktionen erneuert werden muss.
