Thus a light with a low color temperature would have a red tinge
as far as color film results are concerned, while a high value might
produce a bluish cast to the scene. It is amazing how critical the
various types of color film are to Kelvin values.
Kodachrome is probably the best known and most used of the
semi-professional stock; therefore, in the paragraphs which follow
the two types of Kodachrome will be described together with the
lighting required. Other makes of film are coming into use and
increasing in popularity, but Kodachrome was first to be successful
in the field and has remained there ever since. At various
times, and with varying degrees of success, other makers have introduced
color films. Some are still in production and in more or
less demand. Among those already tried are the following: Dufay
Color, Thomascolor, Gaumont Color, Technicolor, Cinecolor,
Multicolor, Magnacolor, Ansco Color, Kinemacolor, Prismacolor,
Agfa Color, Kodacolor, and Kodachrome. Technicolor, of course,
is the best known and most used, but its use is confined to 35 mm
stock.
In color work, duplicating prints is not as simple as in black
and white where it is only necessary to have a good original and
with average care in processing an eminently satisfactory positive
will result. In color work the final use for the film, i.e., whether
it is to be used for duplicating a number of release prints or for
use as a direct reversal, determines to a great extent the type of
film used in the camera. Another source of difficulty arises if the
film to be duplicated is a sound film. It is difficult to reprint a
sound track on color film in many cases, due to the colors appear-
ing in the emulsion around the sound track. If red appears,
as it
often does in some types of emulsion, it can cause some unpleasant
effects which occur because the photoelectric cell used for sound
reproduction usually has a caesium salt as its active element.
The chemistry of color is rather involved; therefore, only one
type of film will be dealt with. The others are similar in most respects.
It should be noted that there are two major means of mak-
ing a color reproduction; one is known as the bipack, and the
