This is a light balancing filter used to decrease the color temperature slightly for a warmer (redder) tone by correcting the tendency toward bluish tones.

For example, the 81A should be selected when using tungsten Type B color film (3200°K) with photoflood lamps (3400°K).

These HMC filters are renowned for their ability to minimize reflection at the filter surfaces which 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.
