Light Balancing Filters
Color
Corre
Ction
FL-B
®
, FL-D
®
Provides correct color, removing harsh green cast
caused by fluorescent bulbs. Use FL-D with daylight film
and FL-B with tungsten film.
❍
Pleasing skintones under fluorescent lighting
without flash.
❍
True-to-life color rendition.
❍
Essential in any environment where ambient
light source is fluorescent.
Neutral Density
.3 , .6 , .9
Neutral Density filters reduce the amount of light
passing through the camera lens without changing the
color of the scene. Especially useful in bright light condi-
tions to help prevent overexposure. Also allows proper
exposure at a wider lens opening for reduced depth-of-
field to highlight a key subject by making the foreground
and/or background out of focus.
❍
Eliminates overly bright, washed-out images.
❍
Balances exposure.
❍
Controls depth-of-field.
❍
Allows slower shutter speeds to produce
blurred motion effects.
