“Pearlescent halo.” Now read that again and really savor the words. Oh, that angelic whisper you’re hearing softly in the background… totally normal. 
 
The Tiffen 4 x 5.65" Pearlescent Filter can be applied to purposely soften contrast and reduce sharpness. This can be useful for high-resolution digital cinematography in order to create a more flattering result of a subject by reducing the appearance of blemishes and softening highlights. Additionally, a pearlescent halo around highlights is created which can further enhance a subject's appearance or produce a desired effect.
 
This filter type's effect becomes approximately twice as strong with each grade number increase.
 
This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch.
