The 62mm Hoya C8 Blue Cooling Filter 62mmallows you to match the white balance of 3800K tungsten-balanced, warm ambient light sources entering the lens to match daylight-balanced 5500K films. C8 filters cool the light source by 1700° Kelvin, or a -80 mired shift, by adding a dark blue to the overall exposure.

Designed for Film Photographers    Adds Dark Blue to Overall Exposure    Reduces Color Temperature by 1700°    6 layers of HMC Multicoating    Equivalent to 80C Filter

The Hoya C8 filter is helpful when:

• You are using daylight-balanced film, the light source is warm, and you want to record accurate colors on the film. Examples of warm light sources are traditional light bulbs and some halogen bulbs.
• You are shooting a daylight-balanced film and you want to create a day-for-night look. The extra blue cast will help give daytime that night feel, especially on overcast days.

Hoya multicoat (HMC) filters are recommended for enhancing the performance of today's multicoated lenses. These popular filters minimize reflection, reduce flare and ghosting, and result in over 97% average light transmission.

Q: 3. Is this the same filter as the Hoya NXT Circular Polarizer filter, just updated?

A: According to Hoya, the NXTPlus filters are improved over the NXT-series because they "use better glass, an improved multi-coating process, more multi-coated layers for better light transmission, AND add a new 'Waterproof' Top-coat to repel water quickly away from the surface which makes it easier to clean and more fun to use."
