Tiffen 77 mm 8-Point/2 mm Star Filter
The Tiffen 77 mm 8-Point/2 mm Star Filter creates multiple points of light, or "stars," that radiate outward from a central light source. This filter is supplied in a rotating mount for precise placement of the star effect.
Wedding photographers will particularly appreciate the value of this filter. For special effects photography, why not offer your client a table photograph of the menu or invitation next to a flickering candle filled with stars? Are you photographing at night? Give that street light a different, more dramatic appearance by using the star filter. Any point light source will produce the effect.
Tiffen's ColorCore glass is produced by a process that involves permanently laminating the filter material between two pieces of optical glass which are polished flat to tolerances of one ten-thousandth of an inch, then mounted in precision aluminium rings.
Note: With an 8-point filter, the numerous star points can tend to dominate the rest of the image, so use it with caution. Generally, medium or larger apertures are sufficient to achieve a good star effect. Always test before critical situations.
- The effect is produced by a series of fine lines etched on the flat optical surface of a transparent filter
- The size and brightness of the star points 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 filter's 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 and will produce a brighter star for a given source
- Lines in one direction produce a two-point star, just a streak at 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)
- Tiffen's ColorCore glass is sealed between two sheets of optical glass. In this way, Tiffen can better control the different densities of their filters and thus create more precise degrees of filtration. This process allows for better colour accuracy compared to glass that is simply tinted and subject to variations during the tinting process
- Tiffen, the industry leader in filters, proudly manufactures its filters in the United States and supports its products with a solid 10-year warranty
