The Tiffen 4 x 5.65″ Water White Neutral Density (ND) Filter is a high-quality filter designed to provide exposure reduction without affecting the coloration of the image. Here are some key features and specifications:

• Exposure Reduction: This ND filter darkens the entire image, allowing photographers to use wider apertures or slower shutter speeds than normally required. This helps in controlling depth of field and conveying movement more effectively.
• Water White Glass: Constructed from Water White glass, this filter ensures high optical clarity and color fidelity.
• ColorCore Technology: The filter is made using Tiffen’s ColorCore technology, which involves laminating the filter substrate between two pieces of optical glass and grinding it flat to a tolerance of 1/10,000th of an inch.
• Size: Measures 4 x 5.65 inches (101.6 x 143.5 mm), making it compatible with various matte boxes and filter holders.
• Versatility: Ideal for pairing with other filters, it is available in different densities (e.g., 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, 2.1) to suit different lighting conditions and creative needs.

This filter is perfect for professional photographers and videographers looking to achieve precise exposure control and creative effects in their work.
