Rosco E-Colour #251 1/4 White Diffusion Roll

This Rosco E-Colour #251 roll supplies 1/4 white diffusion material for professional lighting control. The 48in by 25ft size gives ample coverage for studio, portrait or film sets. It suits photographers and videographers who need to soften light sources without heavy light loss.

Subtle softening with minimal light reduction

The quarter-density formulation spreads light evenly while preserving subject detail and reducing harsh shadows. Glare is minimised and the effect remains natural, so exposure adjustments stay small. The material handles continuous use under hot studio fixtures without degrading.

Cut-to-fit rolls plus sheet option for daily rigging

Each 48in wide roll can be trimmed to any length, letting gaffers create custom frames, flags or overheads on the day. Sheets measuring 21 by 24in are also available for smaller modifiers or quick gel-frame work. The dye-bonded construction resists fading and cracking through repeated handling.

Questions about this item

How do I mount the 48in wide roll and what step causes uneven diffusion?

Cut the 48in roll to length, then clamp or tape it flat to a frame; wrinkles or loose edges create hot spots and uneven spread.

What upkeep or replacement will the E-Colour #251 material need over time?

Replace the roll when the surface yellows, tears, or collects dust that washing cannot remove, as degraded film alters colour balance.

What limit appears first when the 1/4 White Diffusion runs under continuous hot lights?

The 1/4 density transmits most heat, so the base film can warp or discolour before heavier diffusions would under the same fixtures.
