Enhancer Series is designed to intensify specific portions of the color spectrum, without an obvious, "filtered" appearance. Red Enhancer is perfect for making autumn colors, sunsets, brick houses, tomatoes, and other orange-, red-, or brown-toned subjects look their best. Green makes the greens of forests, meadows, hills, and other green subjects vivid. Blue makes blue subjects, such as snowscapes, mountains, and the sea, look their best. Can also be used to reduce the effect of reddish sunlight in early morning or late afternoon and make cloudy skies look blue.
