Opaque black flag or duvetyn used to fully cut light sources, producing hard shadows and defined light-to-shadow edges.
Technical Details
Black solids are made of heavy cotton molton with a surface density of 300-600 g/m², stretched on aluminum or steel frames with a profile thickness of 25-40 mm. The material absorbs 98-99% of the incident light and reflects less than 1% back. Standard versions use nickel-plated or black anodized aluminum with detachable corner connectors for transport. Professional versions feature reinforced corners and interchangeable fabric coverings with piping or grommet fastenings.
History & Development
The first solids were developed by Matthews Studio Equipment in 1955 for Hollywood film studios as an alternative to heavy wooden panels. Mole-Richardson introduced the modular system with standardized C-stand mounts in 1963. In the 1980s, the grip equipment system became established with uniform size designations and accessories. Modern variants made of carbon fiber reduced weight by up to 40% compared to aluminum frames.
Practical Use in Film
Black solids control light spill in artificial light setups and create defined shadow edges for dramatic lighting. In Roger Deakins' work on "Blade Runner 2049," large-format 8' x 8' solids were used to create hard shadow boundaries in interiors. In portrait photography, 2' x 3' solids are used as negative fill to eliminate fill light from reflected walls. Setup is typically done with C-stands and grip arms, with sandbags ensuring stability.
Comparison & Alternatives
Unlike nets (reduce light intensity) or silks (diffuse light), solids block light completely. Single nets reduce the amount of light by one stop, double nets by two stops, while solids offer 100% shading. Modern LED panels with barndoors are increasingly replacing smaller solids in controlled studio conditions. For exterior shoots, large-format solids remain indispensable as they operate independently of power supply and remain effective under direct sunlight.
