About Hoya C4 Cooling Filter

While capturing the perfect shot, the 52mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter plays an essential role in refining the color balance of your images. This high-quality filter cools the ambient light entering the lens by 350 degrees Kelvin, equivalent to a -40 mired shift, by infusing a blue hue into the overall exposure. This process is instrumental in fine-tuning the color or ambiance of your scene to align perfectly with your film's white balance.

This durable filter proves particularly useful when you're using tungsten-balanced film and the light source is warmer than the traditional 3200 degrees K. In such scenarios, where candles and low watt incandescent bulbs serve as light sources, this filter provides the necessary color correction to match your film type.

Moreover, if you're shooting at sunrise or sunset with daylight-balanced film (5500 degrees K) and the overall scene appears too warm, this blue cooling filter steps in to cool the scene, rendering a more natural look to your images.

The multi-coated design of this filter is a standout feature, 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. This ensures that your images are not only color accurate but also of superior quality, free from unwanted reflections and glare.

In essence, the 52mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter is a vital tool for photographers aiming to achieve precise color balance and superior image quality in their work.
