Schneider 4x4" DigiCon # 1/4, Highlight & Shadow Contrast Control Professional Glass Filter

An indispensable tool for professional photographers and cinematographers, the 4x4" DigiCon # 1/4, Highlight & Shadow Contrast Control Professional Glass Filter is expertly designed to enhance your image quality by effectively controlling contrast. This high-quality filter raises black levels while simultaneously lowering highlights, allowing for a higher dynamic range to be recorded when combined with in-camera gamma settings and/or post-production techniques. The result is a detailed image with no loss of resolution or softening, and clean, halo-free highlights.

Crafted by Schneider, a reputable brand synonymous with superior photography equipment, this filter is diamond cut from crystal-clear, water-white optical glass. It is meticulously ground and polished to achieve precise flatness and plane-parallelism, ensuring an exact parallel relationship between the front and back filter surfaces. The perfection of this process is verified by a laser interferometer, and each filter is checked with a densitometer for consistent density and tested with a spectrophotometer for optimal light transmission.

The DigiCon # 1/4 filter's ultra-high consistency allows for seamless filter swapping mid-shoot, with no discernible variation in color or effect. Its unprecedented purity, color saturation, and repeatability virtually eliminate the need for lab color timing correction.

Designed to withstand the most rigorous demands on set or location, this durable filter features Schneider's specially formulated hard anti-reflective (AR) coating. This proprietary coating resists flaking, peeling, and scratching, and reduces light loss and flare to less than 1% per surface, compared to untreated glass that has a light loss of 4% per surface.

The filter's precision mounting rings are made from virtually jam-proof brass, while 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, this versatile filter can be used in front of even the longest lenses without degrading the image quality. This is due to Schneider's stringent quality control, high-quality glass, and superior glass grinding and polishing techniques. The 4x4" DigiCon # 1/4, Highlight & Shadow Contrast Control Professional Glass Filter is a testament to Schneider's commitment to excellence in the field of photography equipment.
