Schneider 4x4" Gold # 1, Hard Edge Graduated Color Professional Glass Filter

Why settle for less when you can achieve superior image quality with the 4x4" Gold #1 Hard Edge Graduated Color Professional Glass Filter This premium filter is designed to deliver an overall warming effect, enhancing healthy skin tones and accentuating the vibrancy of foliage in your shots.

Crafted from crystal-clear, water-white optical glass, each Schneider filter is diamond cut, then meticulously ground and polished to achieve precise flatness and plane-parallelism. This ensures an exact parallel relationship between the front and back filter surfaces, a feature verified by a laser interferometer.

To guarantee perfection, each Schneider filter undergoes rigorous testing. A densitometer checks for consistent density, while a spectrophotometer ensures proper light transmission. Thanks to this ultra-high consistency, cinematographers can swap like filters mid-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. These filters are designed to withstand the most demanding conditions on set or location. Many are equipped with Schneider's specially formulated hard anti-reflective (AR) coating, which resists flaking, peeling, and scratching. This proprietary coating also reduces light loss and flare to less than 1% per surface, a significant improvement over untreated glass that has a light loss of 4% per surface.

Schneider screw-on filters feature 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 the common perception that filters should not be used in front of long length lenses due to the critically short depth of field, Schneider filters defy this belief. Poorly made glass or plastic-resin filters can degrade the image quality, but Schneider filters, thanks to their superior quality control, high-quality glass, and advanced glass grinding and polishing techniques, can be used in front of even the longest lenses without compromising the image quality.
