Hoya 0720 67mm HMC Yellow Filter - Color Correction

The Hoya 0720 67mm HMC Yellow Filter is a K2-type color correction filter designed primarily for black-and-white photography. By absorbing a portion of blue light, it gently darkens blue skies and subtly separates tonal values in foliage, clouds, and architectural subjects, producing images with more natural-looking contrast than unfiltered shots. The yellow K2 effect is considered a moderate correction—stronger than a light yellow Y2 but less dramatic than an orange or red filter—making it a versatile choice for outdoor daylight shooting where you want enhanced definition without an overly contrasty look.

Build quality reflects Hoya's reputation for precision optics. The filter uses optical-grade glass with a six-layer HMC (Hoya Multi-Coating) that achieves over 97% light transmission while suppressing flare and ghosting. The slim black anodized aluminum frame threads securely onto 67mm lenses and is low-profile enough to minimize vignetting, even when stacked with additional filters. With a filter factor of 2 (requiring +1 stop exposure compensation), the light loss is manageable in most daylight scenarios. For photographers still shooting film or using digital cameras with monochrome conversion workflows, this filter provides a reliable, high-quality way to shape tonal contrast at the point of capture.
