• Blue Graduated filters enhance the sky while they underline the colors of mountain landscapes.
• They are also the filters for sea photography where they intensify the white sparkle of breaking waves. They are available in five variations.
A122 - B1 graduated blue filter reduces the light 1 stop.
A123 - B2 graduated blue filter reduces the light 3 stops.
A123L - 2X Light starts with the same neutral density as A122, but feathers the blue almost from the color edge and more gently graduates to clear. One stop of compensation.
A123S - 8X Is the same density of color as A123M but the graduation extends to 3/4 of the filter. Requires 3 stops.
A123F - 8X Full is the same as A123S except that the blue covers the entire filter. Requires 3 stops.
