The LEE Filters 251 Quarter White Diffusion roll proves a 0.3 stop reduction in light transmission.

Diffusion rolls are commonly used in studio photography for creating smooth gradations of light for still life photography. A roll of LEE Diff is also very helpful in creating ad-hoc soft light sources when you only have hard lights at your disposal.

This roll is 1.2m wide and can be hung easily from a C-Stand boom arm, or cut down to whatever size you need.
