The blue color of the filter has a filter factor of 3x, requiring an additional 1.6 stops of exposure to achieve normal results.

The filter is constructed using Tiffen's ColorCore technology, which involves lamenting the filter material between two pieces of optical glass, grounding flat to a tolerance of 1/10,000th of an inch, and mounting within an aluminum alloy ring. The coarse thread version of the filter has a thread pitch of 1.0.
