Tiffen 4 x 5.65" 6 Point/4mm 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.

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 4, 6, and 8 point symmetrical 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 many star lines may tend to overpower the rest of the image, so use it carefully

Generally, mid-range apertures or larger are sufficient to achieve a good star effect; Always test before critical situations

Q: 7. How would this filter behave when shooting a sunrise?

A: While it will depend on the size of the sun in your image (and to some extent, your chosen aperture and focal length), it should behave similar to the sample image on our website. The main difference is, as the sun is both a large and bright light source, the points in the star would be much wider than when photographing a smaller light source or a small specular highlight. The size of the bands would typically depend on the size of the sun in the image. As focal length plays a part in the size of the sun (as well as the sun's position in the sky and/or as it approaches the horizon), wide angle lenses may typically have thinner points, while telephoto lenses would have wider points.
