4 x 5.65" Soft/FX Black Pro-Mist 3 Filter is a combination of the Soft/FX and Black Pro-Mist filters. The 1/2 density of Soft/FX provides a small amount of softening and diffuses strong light entering the lens in order to produce a glowing effect. While the resulting image appears softer and ethereal, there is little loss of clarity or detail.
This filter works by diffusing the light entering the lens with small aberrations; by spreading the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter.
