UV protector Circular polarizer 82mm diameter 812 colour warming filter UV Protection Filters are wise initial investments. They help protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs. If desired they can be left on the lens at all times for protection. Haze filters provide additional benefits of correction for Ultraviolet (UV) light which can register on film and videotape as a bluish cast and can obscure distant details. Ultraviolet filters allow you to correct for the UV effect to varying degrees. Tiffen's exclusive 812 Filter improves skin tones and is ideal for portraits taken on a cloudy day or outdoors in shade on a sunny day. It also absorbs blue cast often caused by electronic flash and adds warmth to pale washed-out flesh tones. Circular polarizers are specifically designed for use with auto-focus SLR cameras. They will also work on manual systems and video cameras without problems. The prepackaged assortments provide a range of artistic possibilities.
