4x4 Grad Storm Blue 3, HESKU 68-110944
Schneider Optics Storm Blue is a rich aqua blue color. As a solid color it can be used to add gray green color to an ocean and sky for a stormy effect. Storm Blue graduated filters can be used to enhance a blue of sky, or when used inverted they can enhance the color of water or cool a snow covered mountain landscape. Note that the filter color MIXES with the sky or water color to create the final 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.
