The 82mm Hoya C2 Blue Cooling Filter 82mmcools the ambient light entering the lens by 200° Kelvin, a -20 mired shift by adding blue to the overall exposure. This filter helps fine-tune the color or look of your scene to match your film's white balance.

Designed for Film Photographers    Adds Blue Cooling Effect    Reduces Color Temperature by 200°    6 Layers of HMC Multi-Coating    Equivalent to 82A Filter

The Hoya C2 filter is helpful when:

• You are using tungsten-balanced film, the light source is warmer than the traditional 3200K, and you need a specific amount of color correction to match your film type. Candles and low-watt incandescent bulbs are examples of warm light sources.
• You are shooting at sunrise or sunset with daylight-balanced film (5500K), and the overall scene is too warm. The filter will help cool the scene for a more natural look.
• 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: 5. Does the plastic of each pouch stick to the filter?

A: Remedy for sticky plastic!! Yes, the plastic will eventually stick to the filters. I have two of the 6-pocket version of this (one for all my 77mm filters, and the other for 82mm filters). Only recently have I noticed the plastic beginning to stick after a period of non-use. I believe this is partly due to the humidity of the south I live in. My remedy - I use lens tissue to wrap around each filter before inserting them back into their designated pocket/pouch. Problem solved! ;)
