Tiffen 4×4 Neutral Density 1.8 Filter

Tiffen 4×4 Neutral Density 1.8 Filter is particularly useful in bright light conditions to help prevent overexposure. It provides a 6-stop reduction in light throughout the entire image, allowing you to use a slower shutter speed or wider aperture than usual.

Key Features: Tiffen 4×4 Neutral Density 1.8 Filter

• Provides a 6-stop exposure reduction
• Solid neutral density filter: the 1.8 density affects the entire image
• Constructed using Tiffen’s ColorCore™ technology
• Does not affect overall colour tone of image
• Eliminates overly bright, washed-out images
• Balances exposure
• Controls depth-of-field
• Allows slower shutter speeds to produce blurred motion effects

Tiffen ColorCore™ Technology

ColorCore technology is a closely guarded proprietary process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision metal rings. The ColorCore process allows Tiffen to control the colour and density of their filters, and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit colour and density variations. When Tiffen filters are ground and polished, the ColorCore is unaffected, so colour and density remain uniform.
