Tiffen 4 x 5.65" UV 2E Pale Yellow Filter

The Tiffen 4 x 5.65" UV 2E Pale Yellow Filter is a specialized UV filter for blocking almost all ultraviolet radiation into the violet region of the visible light spectrum. It helps to prevent unsharpness during ultraviolet fluorescence photography caused by chromatic aberrations due to intense UV lighting situations. It also helps to reduce the over-fluorescence that may occur in the cement between lens elements. In addition to these additional benefits, this filter also compensates for the bluish cast of daylight like clear UV filters. It has a pale yellow tint and a filter factor of 1.2, requiring an additional 0.3 stop exposure for normal results.
