Magenta graduated filters can be used paint a mood in a sky. Instead of a commonplace red/orange, choose to enhance an evening sky with a magenta grad for a zingy red/purple sunset. When used on a blue sky, an unreal science fiction effect can be achieved. When used inverted they can change a landscape, toning down greens and enhancing fall foliage 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.
