The Hoya Yellow-Green Hoya Multi-Coated (HMC) Glass filter has an effect similar to that of the medium yellow filter, but it also darkens red colors. Clouds in the sky gain more contrast. A red roof and red flowers are rendered darker in relation to plant greens (as they would not with a purely yellow filter). The yellow-green filter accentuates the delicate springtime green in nature. It makes portraits more dramatic.
