Formatt Hitech 4x4" 1.5mm Resin Standard Neutral Density (ND) 4 Stops (1.2) Filter

Neutral Density (or ND) filters produce a gray neutral effect and are used to reduce light entering the camera, enabling control over exposure and depth of field without affecting color or contrast. ND's are made in different densities according to the level of light reduction from 1 stop to 4 stops of light and are made from the highest quality 1.5mm optical resin.

Intro to Neutral Density
Neutral Density (ND) filters are the essential filters for digital photography and cinematography. ND filters reduce the amount of light entering the camera and allow the photographer to create the following effects:

• Ethereal waterfalls and streams
• Flat water effect in oceans and lakes
• Streaky clouds
• Motion blur in sports
• Long exposures to remove people from public areas
• Shallow depth of field using fast lenses wide-open
• Adjusting aperture for cinematography

Standard ND
Standard ND filters are an excellent everyday ND filter for the developing amateur photographer. These filters are only available between one and four stops of light reduction. Because they are only available in lower densities, standard ND filters don't suffer from significant color cast and offer an excellent value for money.

Formatt-Hitech Resin
Formatt-Hitech's resin filters are ultra flat, have excellent contrast and are completely transparent to the visible light spectrum. Formatt-Hitech's resin has the highest scratch resistance of any non-glass optical material and it's resistant to most solvents, chemicals, aging and material fatigue. Because of the ruggedness, light weight and portability, resin filters are a great choice for photographers and HDSLR filmmakers. Resin filters are dyed using Formatt-Hitech's exclusive Absorbing Cell Technology process.
