Tiffen Tiffen 49mm 4 Point Star Filter

The 49mm 4pt/2mm Star Filter from Tiffen creates multiple points of light, or "stars," streaking outward from a central light source. This filter comes in a rotating mount for critical placement of the star effect. Wedding photographers will especially appreciate the value of this filter. When it comes to special effects shots, why not offer your client a table shot of the menu or invitation next to a glowing, star-filled candle? Shooting at night? Any point light source will achieve the effect. Tiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminum rings.The effect is produced by a series of thin lines etched into the flat optical surface of a clear filter 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 and 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)Tiffen's ColorCore glass is sealed between two optical glass sheets. In this way, Tiffen can better control the various densities of their filters and thereby create more exact degrees of filtration. This process makes for greater accuracy of color as opposed to glass that is simply dyed and become subject to deviation during the dye process.Tiffen, a leader in the filter industry. /p>
