The Tiffen 4 x 5.65" 4-point/3mm glass star filter creates multiple points of light, or "stars", which extend outwards from a central light source. This can give the scene lighting a more sparkling 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 lines produced are primarily 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 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 trail through the centre of the light
- Tiffen offers symmetrical 4, 6 and 8-point star effects as well as additional asymmetric star patterns through their exclusive Hollywood FX series (North, Hyper, Vector and Hollywood star effects)
- With an 8-point filter, the many star lines can tend to dominate the rest of the image, so use with caution
- Generally, medium or wider apertures are sufficient to achieve a good star effect; Always test before critical situations
