Tiffen 4x5.65" 4 Point/4mm Grid Star Effect Glass Filter

Tiffen 4x5.65" 4 Point/4mm Grid Star Effect Glass Filter Features

• 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
