Cello Cucoloris

A Cello Cucoloris is a specific type of cucoloris (often nicknamed a “cookie”), which is a device used in film, television, and stage lighting. It projects patterned shadows, breaks up light beams, or adds texture to illumination.

Construction:

It is typically constructed from a sheet of “Cello” screen material. This often refers to Cell-O-Glass or similar wire-mesh-reinforced plastic or cellophane sheeting – mounted in a rigid frame. Standard frame sizes include 18″ x 24″, 24″ x 36″, and 4′ x 4′, though custom sizes can be made. The defining characteristic is the intentional use of heat (like a heat gun or torch) to distress the Cello material. This process causes the material to melt, warp, shrink, and burn through in irregular, organic patterns. This creates random openings and textured translucent areas.

Effect and Use:

Unlike hard-cut wooden or metal cucoloris patterns, which produce distinct, sharp-edged shadows, the Cello Cucoloris creates softer, more subtle, and organic shadow patterns. The combination of clear openings, melted/warped translucent areas, and the inherent texture of the Cello material results in dappled light effects.

Common uses include:

• Simulating natural, soft-edged shadows. Like moonlight filtering through sheer curtains or light passing through tree leaves or foliage. Especially when actual foliage isn’t present or practical.
• Breaking up the uniformity of a light source hitting a flat surface to add visual interest and depth. Like a wall or floor.
• Creating abstract textures or mood effects in the background of a shot.

All in all, this tool’s versatility allows users [or professionals] to mimic natural light breakups in a controllable way.
