Schneider 4x4" Black Frost # 1/8, Skin Texture Softening Professional Glass Filter

An essential tool for professional photographers and cinematographers, the 4x4" Black Frost #1/8 Skin Texture Softening Professional Glass Filter delivers a refined aesthetic to your visual projects. This high-quality filter introduces a subtle "black" mist effect, akin to the Black SupaFrost and Black Promist, to gently soften skin textures, flaring highlights, and toning down contrast while maintaining true black levels.

Crafted with precision, each filter is diamond cut from crystal-clear, water-white optical glass. Schneider's meticulous process involves grinding and polishing the glass to achieve a precise flatness and plane-parallelism, ensuring an exact parallel relationship between the front and back filter surfaces. The integrity of this flatness is confirmed with a laser interferometer, guaranteeing the highest level of consistency and quality.

Schneider's commitment to excellence is further demonstrated through rigorous density checks with a densitometer and light transmission tests with a spectrophotometer. This ultra-high consistency allows cinematographers to interchange filters during a shoot without any discernible variation in color or effect. The unparalleled purity, color saturation, and repeatability of Schneider filters virtually eliminate the need for lab color timing correction, streamlining the post-production process.

Durability is a hallmark of Schneider filters, which are engineered to withstand the most demanding on-set or location challenges. Many filters feature a specially formulated hard anti-reflective (AR) coating that resists flaking, peeling, and scratching. This proprietary coating also minimizes light loss and flare to less than 1% per surface, a significant improvement over untreated glass, which can experience a light loss of 4% per surface. Schneider's screw-on filters boast precision brass mounting rings that are virtually jam-proof, while unmounted laminated filters are safeguarded against delamination and edge chipping by Schneider's unique Edge Seal. This seal also mitigates edge reflection and edge flare.

Dispelling the common misconception that filters should not be used with long focal length lenses due to the critically short depth of field, Schneider filters excel in maintaining image integrity. Even when placed in front of the longest lenses, these filters, diamond-cut from the finest optical glass and polished to exacting standards, ensure no visible compromise in image quality. Whether used individually or stacked, Schneider filters are the definitive choice for achieving clarity, light transmission, and color fidelity with any lens.

The 4x4" Black Frost #1/8 filter is a versatile and innovative solution for photographers and cinematographers seeking to enhance their imagery with professional, cinematic effects while relying on the durability and consistent performance that Schneider is renowned for.
