Hoya 46mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter

You can achieve professional-level color accuracy with the 46mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter. This filter is designed to adjust the color temperature of the ambient light entering your lens by a significant 350-degree Kelvin (-40 mired shift), introducing a blue hue to your overall exposure. This feature is particularly useful when you need to match your scene's color to your film's white balance.

The C4 color correction filter proves to be an invaluable tool in specific scenarios. For instance, when you're using tungsten-balanced film and the light source is warmer than the conventional 3200-degree K, such as with candles or low watt incandescent bulbs. It also comes in handy when you're capturing the beauty of sunrise or sunset with daylight-balanced film (5500-degree K), and the scene appears too warm. This filter will effectively cool down the scene, rendering a more natural look.

The Hoya C4 filter is equipped with HOYA Multi-Coat (HMC) technology, a feature that is highly recommended for optimizing the performance of today's multicoated lenses. These sought-after filters are designed to minimize reflection, reduce lens flare and ghosting, and ensure over 97% average light transmission. With the 46mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter, you can enhance your photography experience and capture images with true-to-life colors.
