Light balancing filters
With 82A
These are light balancing filters
used to increase the color
temperature slightly for a cooler
(bluer) tone. Corrects the
tendency toward reddish tones.
As an example, select the 82B
when using tungsten Type B film
(3200ºK) with ordinary household
100W electric bulbs (2900ºK).
These filters are also used to
prevent the reddish tones in early
morning or late evening light for
natural skin tones. These filters
can be used together, but do not
mix the 81 and 82 series filters
since they cancel each other out.
