Mixed Light Sources
Under mixed light conditions, the basic filter configura-
tion should suit the main light source. In the case of
cameras with TTL metering, there is no need for addi-
tional exposure compensation for any CC filter(s) used.

COMPENSATION
COMPENSATION
No exposure correction or color balance compensation
is required for exposures within a shutter speed range of
1/4000 second to 1 minute. However, for exposures of 2
minutes or longer, ‘reciprocity law failure’-related color
balance and exposure compensations are required.
