Tiffen 6.6 x 6.6" 4 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

Related Questions and Answers

Q: 1. Will the 58mm vector star effect filter by Tiffen fit on my 18-270mm Tamron lens?

A: No it will not. Tamron has had two different versions of an 18-270mm lens, and neither had this filter thread size. The current version of the lens is the PZD version which has a 62mm sized filter thread. The previous version had a 72mm sized filter thread. To confirm which size your lens requires you may simply remove the lens cap and look at the number on the underneath side. If you still need further help determining the proper size for your lens, you may email askbh@bhphoto.com and they can assist you.

Q: 2. Is there any light loss?

A: From testing in the store, we saw no visible change in exposure, likely indicating a 1x filter factor and almost complete light transmission (minus any potential loss from coatings and glimmerglass particulates).

Q: 3. What's the difference between this and a Black Promist Filter?

Q: 9. I'd like to order a Tiffen GlimmerGlass 49 filter for a Leica Q3 I have on order. What threads option and grade do I need?

A: The Leica Q3 accepts 49mm filters. Regarding the GlimmerGlass grade that you need it depends on how much of an effect you want in the image. How soft you want the skin to be, how much you want the highlights to bloom. For a very small amount just to cut out some of the sharpness of the digital sensor I would recommend the 1/4 grade.
