Schneider Optics Gold is a rich warm color. As a solid color it gives an overall warming effect and can be used to create a feeling of late afternoon sunlight. It does good things for skintones and accentuates foliage. Gold graduated filters can be used to enhance an evening sky, or when used inverted they can enhance a landscape, warming cornfields or desert sand, without affecting the sky color. This filter is available in strengths of 1, 2, and 3. These strengths achieve a subtle, moderate, or bold effect. Schneider makes both soft-edge(SE) and hard-edge(HE) Graduated Color filters. Typically, soft-edge filters are used with wide to medium-angle lenses because these lenses have greater depth of field. Hard-edge filters are preferred for use with telephoto lenses or for bold transitions.
