     Slightly stronger warming effect than the 81A, the 81B corrects the tendency toward bluish tones. For example, the 81B should be selected when using tungsten Type B color film (3200°K) with photoflood lamps (3500°K). The 81B can also be used to add a noticeably warm cast to a daylight scene.

    HMC (HOYA MULTI COATED) These popular filters are renowned for their ability to minimize reflection at the filter surfaces that reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well-balanced color. HOYA HMC filters are recommended for enhancing the performance of today's multicoated lenses.
