Schneider 4x4" Amber # 1, Soft Edge Graduated Color Professional Glass Filter

Where the art of photography meets the science of light manipulation, the 4x4" Amber #1 Soft Edge Graduated Color Professional Glass Filter stands as an essential tool for cinematographers and photographers alike. This Schneider filter, renowned for its ability to mimic the warm glow of candlelight or a firelit scene, is meticulously crafted from crystal-clear, water-white optical glass.

Each filter is diamond cut, then ground and polished to achieve precise flatness and plane-parallelism, ensuring an exact parallel relationship between the front and back filter surfaces. This precision is confirmed by a laser interferometer, guaranteeing perfection in every piece.

The Schneider filters are further examined with a densitometer to ensure consistent density and tested with a spectrophotometer to verify optimal light transmission. This rigorous quality control process results in an ultra-high consistency that allows for seamless filter swapping mid-shoot, with no 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. They are designed to withstand the most demanding conditions on set or location, with many featuring Schneider's 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.

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

Contrary to common belief, Schneider filters can be used in front of even the longest lenses without compromising image quality. This is due to the high-quality optical glass used, and the meticulous grinding and polishing techniques employed in their manufacture. Schneider filters offer unsurpassed clarity, light transmission, and color saturation, making them the clear choice for any lens, even when stacked.
