GRADUATED NEUTRAL-DENSITY FILTER helps to darken specific areas of an image, such as bright sky, while allowing for a normal, unaffected exposure in the other regions of the image.
GRADUATED SUNSET FILTER is designed to create an intentional warming effect of an image. It helps to enhance an existing sunset within a scene, or to simulate a sunset in order to enhance a hazy or colorless sky.
GRADUATED SKY BLUE FILTER is designed to add blue to a hazy or colorless sky. The 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.
A CIRCULAR POLARIZER FILTER cuts glare and reflections, allowing deep, natural colors to show through with great saturation. This effect is most noticed in blue skies where white clouds will pop from the darkened blue skies.
