The Hoya 77mm HMC 80C Light Balancing Filter is uniform in color and with a mired shift value of -81, can be applied to purposely create a cool 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 77mm HMC 80C Light Balancing Filter is also useful for balancing light sources with a color temperature of 3800K for daylight film, which is designed to accurately reproduce colors under 5500K light sources.

The greater the difference between the color temperatures they are designed to correct for under 5500K, light balancing filters for daylight film are considered to be progressively stronger in their effect when used to cool a daylight image.

This filter is constructed from optical glass for increased clarity and color fidelity. Its aluminum-alloy filter ring is durable while remaining lightweight. To prevent internal ghosting and reflections, each glass surface includes three layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

When used, the Hoya 77mm HMC 80C Light Balancing Filter's 0.3 density darkens the entire image by 1 stop. This reduction in exposure can be compensated for by adjusting the aperture setting of the lens it is placed on, or the shutter speed of the camera being used.

    77mm HMC 80C Light Balancing Filter is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from Quality Filter that Does the Job I wanted to document some antique trolley cars at a museum in Connecticut using Kodachrome film, while that could still can be done. To light the large dark interior of the carbarn where the trolleys are kept, I used some big old No. 22 flashbulbs which produce a lot of light but can be triggered with a small 9-volt battery that fits in a shirt pocket. To balance the 3800K light from the flashbulbs with the daylight balanced Kodachrome, I bought this Hoya 80C filter. The filter did just what it was supposed to do.

    Rated 4 out of 5 by from Great for DSLR shooting If you work with HDSLR's and really are concerned with your blue's this is perfect for bumping it up. A lot of digital chips do a poor job of capturing blue throught the spectrum and if you are really pushing the levels in post it is best to have all of your channels captured as equally as possible and get the most information that you can get. This will help greatly with that.
