How to Select Color Conversion and

Light Balancing Filters

Each color film is made to reproduce colors correctly when used with a

specific light source. When other light sources are used, color conversion

filters must be used to match the color of the light source to the film

capabilities. Light balancing filters are used for slight adjustments of the

color of the light source for cooler (bluer) or warmer (redder) tones.

The following table is given for your convenience in selecting the proper

filter. To determine the necessary filter, make a line from the original light

source (T1) to the converted light source (T2). The proper filter will be

indicated at the point where this line crosses the center column.
