The 5.65 x 5.65" Classic Black Filter from Schneider Optics is a great filter to use for anyone who wants to create an era of days gone by. A soft, diffused image is created that resembles the cinema look of the 40s and 50s. It can also help to create an even transition from scene to scene. This filter will flare your highlights, reduce contrast and help create a mood. Blacks will be deeper.
