Product details:

Adding color to a specific region of your image, the 100 x 150mm Soft-Edge-Edge Graduated Sky Blue 2 Filter from LEE Filters produces a realistic greenish blue coloration to isolated portions of the frame with neutral results maintained in the opposite half of the image. This filter's coloring is densest at one edge and tapers to clear by the middle, with a soft-edged transition between the color and clear areas. This filter is ideally suited for adding color to an otherwise plain scene or to emphasize and complement existing tones in your image. This filter is constructed from optically correct resin, measures 100 x 150mm, and is compatible with the LEE 100mm filter holder.
