Tiffen Glimmerglass filter strength ranges from 1/8 – 5, with 1/8 being the least pronounced effect

Glimmerglass is a line of diffusion filters that produces a soft clean halation around practical and specular light sources, while keeping an apparent sharpness on the overall image. On close ups, the apparent sharpness and fine detail is kept as the effect of the filter lowers contrast while softly rolling into the shadow area. This low contrast affect moderately mutes bright colors. This makes the lower end of the glimmer glass diffusion line produce a non-destructive or invasive look.

Even at heavier densities, the filter never becomes overly powerful in its spread of halation.
The Glimmerglass series of filters also has a benefit of sparkling when viewed, which can add reassurance to your talent when shooting beauty; that way you can fully concentrate on the look of your shot.

ColorCore

Tiffen camera filters are manufactured using ColorCore technology, a closely guarded proprietary 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 metal rings.
The ColorCore process allows Tiffen to control the color and density of Tiffen filters, and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations.
