Formatt 77mm Graduated Neutral Density (ND) 0.6 Filter

A standard set of ND's is 0.3, 0.6, 0.9 and 1.2. This represents 1 to 4 stops of light reduction ¹

Please Note:

Heavier ND's can be manufactured but are not standard stock items

Neutral Density Filters Have Four Main Uses

To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars

To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background

To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations

To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure

Neutral Density Factors

ND.3 (exposure adjustment = 1 stop, reduces ISO 1/2)

ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)

ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)

ND1.2 (exposure adjustment = 4 stops, reduces ISO 1/16)

Formatt Grads are Available in Four Types

Soft Edge - Half clear, half colored with a smooth transition to full density. Generally used with medium to wide angle lenses

Hard Edge - Half clear, half colored with a definite less subtle transition. For use with long focal length lenses

Razor Edge - As hard edge but with a solid transition line for shooting corners of buildings, knife-edge horizons or when a very bold transition is required

Blender - The grad line is right at one edge of the filter so the color change runs from top to bottom. Perfect for irregular objects and skylines
