The Tiffen 4 x 4" 4 Point/2mm Star Glass Filter creates multiple points of light, or "stars", which radiate outward from a central light source. This can give the scene lighting a more sparkly and glamorous appearance. This effect is produced by a series of fine lines etched onto the flat optical surface of a clear filter.

The size and brightness of the star branches produced depend mainly on the size, shape, and brightness of the light source.


Features:

- You have additional control through the choice of a particular spacing between the filter lines; These spacings are measured in millimetres and range from 1 mm to 4 mm
- A 1 mm spacing has twice as many lines as a 2 mm spacing; It will produce a brighter star for a given source
- Lines in one direction produce a two-pointed star, just a streak across the centre of the light
- Tiffen offers symmetrical 4, 6 and 8 point star effects as well as additional asymmetrical star patterns through their exclusive Hollywood FX series (North, Hyper, Vector and Hollywood star effects)
- With an 8-point filter, the numerous star branches may tend to dominate the rest of the image, so use it with care
- Generally, medium or larger apertures are sufficient to achieve a good star effect; Always test before critical situations
