Hoya 49mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter

Because precise color balance is essential in photography, the 49mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter offers a professional solution for photographers looking to achieve accurate color representation in their images. This specialized filter is designed to cool down the color temperature of the light entering your lens by 350 degrees Kelvin, which corresponds to a -40 mired shift. By introducing a subtle blue hue to the overall exposure, it effectively counteracts excessively warm tones, ensuring that your photographs maintain a natural and balanced look.

Crafted with the discerning photographer in mind, the filter is particularly useful in scenarios where the ambient light source has a higher color temperature than your film's white balance setting. For instance, when shooting with tungsten-balanced film in the presence of warmer light sources such as candles or low wattage incandescent bulbs, this filter provides the necessary color correction to match the film type and preserve the intended aesthetic.

Additionally, the filter proves invaluable during golden hour photography. When using daylight-balanced film rated at 5500 degrees Kelvin, the natural warmth of sunrise or sunset scenes can overwhelm the film's white balance. The C4 filter steps in to cool the scene, rendering it with a more accurate and pleasing color temperature that reflects the true essence of the moment.

The filter's utility is further enhanced by its Hoya Multi-Coat (HMC) technology. This advanced coating is engineered to augment the performance of today's multi-coated lenses. By minimizing reflections and reducing the likelihood of flare and ghosting, the HMC ensures that over 97% of light is transmitted through the filter, preserving image clarity and sharpness.

Whether you're a professional photographer seeking to perfect your film's color fidelity or an enthusiast looking to enhance your images' visual appeal, the 49mm C4 Blue Cooling Color Correction Multi-Coated Glass Filter is an indispensable tool in your photography kit. Its precision engineering and high-quality construction make it a reliable choice for achieving consistent and accurate color correction in a variety of lighting conditions.
