The Formatt Supermist Clear Filter is both a diffusion filter and a good way to take the edge off of today's super sharp HD lenses.  It is great for establishing a dreamy mood, yet, retains the overall sharpness of the image without making it look too soft.  It lowers contrast by opening the shadows but does not spoil the overall look of the photo.

Formatt, a company with three generations of professional filter-making experience produces every filter to the highest technical standards. The finest materials, together with state of-the-art production technology have resulted in a standard of optical excellence unmatched anywhere else.
