Description

The C2 color correction filter cools the ambient light entering the lens by 200° kelvin (-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.

The Hoya C2 filter is helpful when:

• You are using tungsten-balanced film and the light source is warmer than the traditional 3200° K 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 (5500° K) and the overall scene is too warm. The filter will help cool the scene for a more natural look.

HOYA Multi-Coat (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.
