Schneider 4x4" White Frost # 1/4, Diffusion & Contrast Reducing Professional Glass Filter

Where professional photography and videography meet, Schneider White Frost filters are the go-to tools for picture styling and mood modification. These high-quality filters subtly flare highlights and gently tone down contrast, all while maintaining image resolution and color reproduction.

Each Schneider filter is diamond cut from crystal-clear, water-white optical glass, ensuring the utmost clarity for your images. These filters are meticulously ground and polished to achieve precise flatness and plane-parallelism, a process verified by a laser interferometer for perfection.

Consistency is key with Schneider filters. Each one is checked with a densitometer for consistent density and tested with a spectrophotometer for optimal light transmission. This level of consistency allows cinematographers to swap filters mid-shoot without any discernible variation in color or effect. The unprecedented purity, color saturation, and repeatability of Schneider filters virtually eliminate the need for lab color timing correction.

Designed to withstand the most rigorous demands on set or location, many Schneider filters feature a specially formulated hard anti-reflective (AR) coating. This proprietary coating resists flaking, peeling, and scratching while reducing light loss and flare to less than 1% per surface. This is a significant improvement compared to untreated glass, which has a light loss of 4% per surface.

Schneider's screw-on filters are designed with virtually jam-proof brass precision mounting rings. Unmounted Schneider laminated filters are protected against delamination and edge-chipping by Schneider's unique Edge Seal, which also reduces edge reflection and edge flare.

Contrary to common perception, Schneider filters can be used with long length lenses without compromising image quality. This is due to the high-quality control, superior glass quality, and precise glass grinding and polishing techniques employed by Schneider. Diamond-cut from high-quality optical glass, these filters offer unsurpassed clarity, light transmission, and color saturation with no visible compromise of image quality, even when stacked. Schneider filters are the clear choice for any lens, making them a versatile and effective tool for all photographers and cinematographers.
