Tiffen 4 x 5.65" Combination Color Conversion 85 /Neutral Density 0.6 Glass Filter

85 Series Conversion Chart

• An 85 decreases the color temperature from 5500-3400° Kelvin

• An 85A decreases the color temperature from 5500-3100° Kelvin

• An 85B decreases the color temperature from 5500-3200° Kelvin

• An 85C decreases the color temperature from 5500-3800° Kelvin

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)

• ND 1.2 (exposure adjustment = 4 stops, reduces ISO 1/16)

• ND 1.5 (exposure adjustment - 5 stops, reduces ISO 1/32)
