The Formatt 6.6 x 6.6" Day for Night Cool 3 Filter is a great way to create images simulating dusk or night-time while filming during the day. This filter adds a bluish-lavender tint creating a low contrast, evening look to the image. Care must be taken in the application of this filter since detail will be lost in the low contrast portion of the picture.  

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.

• Cool Day for Night is based on the perception that moonlight is cool, therefore bluish in color
• To produce this effect Formatt uses a shade of lavender for visual coolness while maintaining realistic flesh tones
• Monochrome Day for Night is based on the theory that lower light levels will reduce the sensitivity of the eye, creating a more 'silvery moon' type effect; this filter effects the color balance of the image so fine tuning of color timings is essential
• Each filter is manufactured from Schott Glass
• Absolute consistency in color and density to Kodak Wratten standards
• Precision grinding and polishing result in unbeatable optical flatness allowing use on even ultra-long focal length lenses
• Filter edges are protected with a unique frame for maximum protection and easy handling
