Cokin Z-PRO 138 FLW Graduated Resin Filter

Cokin Z-PRO 138 FLW Graduated Resin Filter - An FL-W filter is used to balance daylight film under warm white or white type fluorescent lamps. An FL-D filter is used when you wish to correct for the greenish tone that appears when shooting daylight film under general purpose fluorescent lighting. An FL-B filter is used to correct the color balance when shooting tungsten film under fluorescent lighting.

Cokin color graduated filters are color-toned in one half of the filter and have a smoothly graduated transition into the clear portion. Colored and clear image portions can be brought into the desired position by adjusting the filter in the holder. This unusual filter is for correcting fluorescent lights on part of the image only, i.e. a ceiling with fluorescent lights.
