About Hoya C4 Cooling Filter

Let the 58mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter elevate your photography by expertly managing color balance and light penetration. This high-quality filter is engineered to cool the ambient light entering your lens by 350 degrees Kelvin (-40 mired shift), adding a subtle blue hue to your overall exposure for precise color accuracy.

Ideal for photographers who demand effective color correction, this filter is indispensable when working with tungsten-balanced film in the presence of warmer light sources, such as candles or low wattage incandescent bulbs, which typically exceed the standard 3200 degrees Kelvin. It also excels during golden hour shoots with daylight-balanced film, ensuring that the natural warmth of sunrise or sunset scenes is not overly pronounced, thus maintaining a true-to-life color representation.

The multi-coated design of this filter is a testament to its superior construction, significantly reducing reflections and glare to enhance image clarity. The advanced coating technology ensures an impressive 97% average light transmission, optimizing the performance of today's sophisticated multicoated lenses.

Whether you're a professional photographer or an enthusiast looking to refine the color fidelity of your images, the 58mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter is an essential tool for achieving a more natural and balanced color palette in your photography.
