Tiffen Star FX filters create 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 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? Make that street lamp take on a different, more dramatic appearance by using the star filter. Any point light source will achieve the effect.
