Schneider 4x4" Amber # 2, Hard Edge Graduated Color Professional Glass Filter

Because the 4x4" Amber #2 Hard Edge Graduated Color Professional Glass Filter is designed to simulate the warm hues of candlelight or a firelit scene, it is an essential tool for photographers seeking to create atmospheric and evocative images. Crafted from crystal-clear, water-white optical glass, this Schneider filter is diamond cut, ground, and polished to achieve precise flatness and plane-parallelism, ensuring an exact parallel relationship between the front and back filter surfaces.

The meticulous manufacturing process includes verification by a laser interferometer, densitometer checks for consistent density, and spectrophotometer testing for optimal light transmission. This rigorous quality control results in an ultra-high consistency that allows photographers and cinematographers to interchange similar filters during a shoot without any noticeable variation in color or effect.

Thanks to the unprecedented purity, color saturation, and repeatability of Schneider filters, the need for lab color timing correction is virtually eliminated. These filters are designed to withstand the most demanding conditions on set or on location. Many of them feature Schneider's specially formulated hard anti-reflective (AR) coating, which is resistant to 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, which has a light loss of 4% per surface. Schneider's screw-on filters are equipped with virtually jam-proof brass precision mounting rings, while unmounted Schneider laminated filters are safeguarded against delamination and edge-chipping by Schneider's unique Edge Seal. This innovative seal also minimizes edge reflection and edge flare.

Contrary to the common perception that filters should not be used with long length lenses due to their critically short depth of field, Schneider filters, thanks to their high-quality construction and precise lens-making standards, can be used confidently with even the longest lenses. They offer unsurpassed clarity, light transmission, and color saturation without any visible compromise of image quality. Even when stacked, Schneider filters remain the clear choice for photographers and cinematographers seeking to enhance their work with any lens.
