Hoya 77mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter

Enhance your photography with the 77mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter, expertly designed to cool the ambient light entering your lens by 350 degrees Kelvin (-40 mired shift). This high-quality filter adds a blue hue to your overall exposure, fine-tuning the color of your scene to perfectly match your film's white balance.

Ideal for use with tungsten-balanced film, this filter proves invaluable when your light source is warmer than the traditional 3200 degrees K. It provides the precise color correction needed to match your film type, making it perfect for capturing scenes lit by candles or low watt incandescent bulbs.

Furthermore, if you're shooting at sunrise or sunset with daylight-balanced film (5500 degrees K) and find the scene too warm, this blue cooling filter will help to cool the scene for a more natural look.

The filter's multi-coated design is a standout feature, reducing reflections and glare, and improving image quality and contrast. This effective coating minimizes reflection, reduces flare and ghosting, and results in over 97% average light transmission.

The 77mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter is an essential tool for photographers seeking to improve the overall color balance, contrast, and sharpness of their images.
