Black mesh fabric with square openings that reduces light intensity evenly without color shift.
Technical Details
Standard Light Grid Cloth is available in densities of 1/4 Grid (6mm openings), 1/2 Grid (3mm), and Full Grid (1.5mm). The base material consists of heat-resistant polyester or silk with black nylon threads forming the grid structure. Light transmission is approximately 85% for 1/4 Grid, 60% for 1/2 Grid, and 30% for Full Grid. Standard sizes range from 6x6 feet to 20x20 feet, with a material thickness of 0.2-0.4mm. The grid pattern, through diffraction, creates characteristic soft shadows with minimal color temperature shift of a maximum of 200K.
History & Development
Light Grid Cloth was developed in 1974 by Cinematographer James Crabe for "Rocky" to diffuse harsh sunlight more controllably than with conventional diffusers. Grip equipment manufacturer Matthews Studio Equipment launched the first commercial version in 1978. In the 1980s, Grid Cloths became standard for exterior shots, especially after Roger Deakins' innovative use in "Barton Fink" (1991). Modern LED-optimized versions since 2010 account for the changed spectral characteristics of digital lighting.
Practical Application in Film
Grid Cloth is primarily used for daylight shooting to soften harsh shadows without eliminating the direction of light. In "Mad Max: Fury Road" (2015), DoP John Seale used large-scale 1/4 Grid setups over vehicle scenes for even illumination during 120fps shots. The structured light fall is particularly suitable for portraits, as the grid pattern emphasizes natural skin textures. Disadvantages include the susceptibility of large areas to wind and potential moiré effects when shooting at certain angles to LED panels.
Comparison & Alternatives
Unlike Silk or Diffusion, Grid Cloth creates sharper shadow gradients due to its structured pattern. While opal diffusers scatter light evenly, Grid Cloth maintains the original light direction with reduced intensity. Modern alternatives include digital light shaping through DMX-controlled LED arrays or laser-perforated films with variable opening patterns. For interior shots, bounce lighting with white duvetyne often replaces the more complex grid setup.
