Star effect filters


What is the difference between these effect filters?
Do they look the same?
Does some of them look like "the cheap version"?

- "6x cross screen star effect" (B+W, Hoya)
- "6 point star effect" (Hoya)
- "6 point/2 mm grid star effect" (Tiffen)

Here are some descriptions from B&H. Hope it helps.

6x Cross screen star effect (B+W):
The grid structure of this attachment is designed so that a 6-point star is created from point light sources and reflections. The mount turns to allow the photographer the freedom to decide the orientation of the star effect.

6 point star effect (Hoya)
"Hoya's Star 6 Cross Screen is designed so that a 6-point star is created from point light sources and reflections."

6 point/2mm (Tiffen)
Star filters 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 a function of the size, shape, and brightness of the light source. You have additional control through the choice of a particular spacing between the lines on the filter. These spacings are measured in millimeters and range from 1mm to 4mm. A 1mm spacing has twice as many lines as a 2mm spacing. It will produce a brighter star for any given source. Lines in one direction produce a two-pointed star, just a streak through the center of the light. Tiffen offers symmetrical rectangular Star Effect filters (with 1-4mm grid options) in 4 and 6 points. In addition, Tiffen offers asymmetrical star patterns through their exclusive Hollywood/FX Series (North, Hyper, Vector and Hollywood star effects). Generally, mid-range apertures or larger are sufficient to achieve a good star effect. Always test before critical situations.
