Tiffen Filters 4x4 Star 4PT 3mm Filter - 44STR43
Tiffen 4 x 4" 4 Point/3mm Grid Star Effect Glass Filter create multiple points of light, or "stars," streaking outward from a central light source. This can make lighting within the scene take on a more glittering, glamorous appearance. This effect is produced by a series of thin lines etched into the flat optical surface of a clear filter.
The size and brightness of the star lines produced are first a function of the size, shape, and brightness of the light source.
