The HOYA FOG filters have a frosted surface that lightly veils the entire picture in a pleasing dreamlike fog effect. There are two Hoya FOG filters, a FOG A and the stronger FOG B. Both can be used together to produce an effect similar to dense fog. The effect can be varied by changing the aperture of the lens, but stopping down too far will reduce the effect. These two filters are also available as a set.
