Used Schneider Optics 4x4" Neutral Density ND 0.9, Soft Edge Graduated Color Professional Glass Filter.

Bring your photography to the next level with the 4x4" Neutral Density ND 0.9 Soft Edge Graduated Color Professional Glass Filter. Crafted by Schneider, a leader in high-quality photography equipment, this filter is designed to provide superior control over exposure and depth of field under various lighting conditions without affecting color or contrast.

Unlike other brands, Schneider's Absorptive ND filters are a neutral gray, achieved with meticulous laboratory precision. This ensures that your images maintain their true colors, regardless of the lighting conditions.

Each Schneider filter is diamond cut from crystal-clear, water-white optical glass, then ground and polished to a precise flatness and plane-parallelism. This exact parallel relationship between the front and back filter surfaces is verified by a laser interferometer, ensuring perfection in every piece.

The filters are then checked with a densitometer for consistent density, and tested with a spectrophotometer for proper light transmission. This ultra-high consistency allows photographers and cinematographers to swap like filters mid-shoot with no discernible variation in color or effect.

Schneider filters are designed to withstand the most rigorous demands on set or location. They feature Schneider's specially formulated hard anti-reflective (AR) coating to resist flaking, peeling, and scratching. This proprietary coating also 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 4x4" Neutral Density ND 0.9 Soft Edge Graduated Color Professional Glass Filter is versatile and suitable for use with a variety of lenses and camera models. Whether you're a professional photographer or a passionate hobbyist, this filter will enhance your photography and provide a wider range of creative possibilities.

Schneider filters have no such problems as image degradation, even when used in front of the longest lens. This is due to the high-quality control, superior glass, and advanced glass grinding and polishing techniques used in the manufacture of these filters.
