Hoya 52mm 81A Warming Multi Coated Glass Filter
Hoya A-5281A-GB Overview
The Hoya 52mm HMC 81A Light Balancing Filter is uniform in color and with a mired shift value of +18, can be applied to purposely create a warm cast over an entire image. This effect can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. The Hoya 52mm HMC 81A Light Balancing Filter is also useful for balancing light sources with a color temperature of 3400K for type B tungsten film, which is designed to accurately reproduce colors under 3200K light sources.
The greater the difference between the color temperatures they are designed to correct for over 3200K, light balancing filters for type B tungsten film are considered to be progressively stronger in their effect when used to add warmth to a daylight image.
