A unique filter for affecting contrast when working in black and white, the 49mm X0 Yellow-Green HMC Filter from Hoya helps to lighten green tones while darkening red tones. It is particularly well-suited to outdoor portraiture due to its ability to lighten foliage and produce corrected skin tones with enhanced facial detail.
The filter is constructed from optical glass and has a six-layer HMC coating to reduce surface reflections and glare in order to retain high image accuracy, clarity, and contrast. It is mounted within a durable, lightweight aluminum ring, which has a hard anodized finish to guard against wear.
