A filtration rule that you should remember is that a filter
transmits light of its own color and absorbs its complement.
Yellow is composed of red and green, thus it will transmit red
and green and absorb (or subtract) blue which is its complement
(page 11, para 4c).
Hue is simply the "name" given to a color (page 16, para 6a).
Since tungsten light sources, for which these films are balanced,
are high in red content, tungsten film is made especially
sensitive to blue in order to counteract the red; this will give
the colors a more natural appearance (page 24, para 12a(3)).
+/- one-half stop
Slide films have a very narrow latitude for exposure.
most part, they must be right on target; they will stand +/- one-
half stop tolerance, however, with acceptable results.
slide films, it is better to err on the side of underexposure
rather than overexposure (page 29, para 15b(l)).
