Cavision 4 x 4" Soft-Edge Graduated Neutral Density 0.6, Soft-Edge Graduated Blue 0.3, and Soft-Edge Graduated Orange 0.3 Filter Kit (4mm Thick)

Helping to balance the overall exposure within a high-contrast scene, this 4 x 4" Graduated Neutral Density 0.6 Filter from Cavision neutralizes the exposure between a dark foreground and a bright sky. Half of this filter has a 2 stop, 0.6 neutral density area and the other half is clear, with a medium-soft-edged transition between the two for a natural appearance when photographing uneven or undulating horizon lines. By reducing the exposure in selective areas, you can balance the overall exposure of the scene in order to gain detail in both bright and dark areas.

This filter is constructed from 4mm-thick optical glass to maintain image clarity and it measures 4 x 4".

The Cavision 4 x 4" Soft-Edge Graduated Blue 0.3 Filter is compatible with filter holders that can accommodate 4mm-thick, 4 x 4" rectangular filters. It can be used to add blue to a hazy or colorless sky. When used instead of a polarizer filter to enhance the sky within an image, the desired effect can be applied only to the sky, without any unwanted polarization or additional contrast to any part of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. This filter has up to a 0.3 density and reduces light from entering a lens by up to one stop.

The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. This filter has up to a 0.3 density and reduces light from entering a lens by up to one stop.
