The Tiffen 4 x 5.65" Warm UV 17 Filter is a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. This filter is especially useful when photographing at high altitudes or around bodies of water. No additional contrast is provided, allowing you to pair this filter with others. This filter attenuates approximately 97% of UV radiation, slightly less than a UV 2A filter.
This filter also provides the effects of an 812 filter for adding more warmth to imagery in order to create more pleasing skin tones. It counters the bluish color casts of electronic flash, overly shadowed conditions, and other overwhelming cool colorations.
The UV filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.
Tiffen filters are 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. This filter measures 4 x 5.65" / 101.6 x 114.3mm.
