KODAK Light Balancing FiltersLight-balancing filters enable the photographer to make
m i n o r adjustments in the color quality of illumination to
obtain cooler (bluer) or warmer (yellower) color re n d e r i n g .
One of the principle uses for KODAK Light Balancing
Filters is where li ght sources frequently exhibit color
t e m p e r a t u res diff e rent than that for which a color film is
balanced. When using a color temperature meter to deter-
mine the color temperature of prevailing light, you can use
the table below, which converts the prevailing temperature
to either 3200 K or 3400 K.
*These values are approximate. For critical work, check by accurate tests, especially
if you use more than one fil t e r .
