The Tiffen 4 x 5.65 In. Pearlescent 1/4 Filter creates a subtle new look with a slight softening of contrast and a luxurious Pearlescent halo around highlights. These new filters aid cinematographers in taking the edge off the image from modern lenses and cameras, especially with 4K acquisition sensors. This increase in sharpness and contrast can be overpowering when shooting talent or environments that do not require as much intense detail, and it's here where Tiffen's Pearlescent filter look comes into its own.Features: Creates a special "atmosphere" by softening excess sharpness and contrastGenerates a pearlescent halo around highlightsLighter grades help tone down the excessive sharpness and contrastMaintains focusOften used to mute colors for exquisite pastel tonesNew Tiffen Pearlescent Filters are available in: 4 x 4, 4 x 5.650, 6.6 x 6.6 and 138mm sizes and Grades 1/8, 1/4, 1/2, 1 & 2
