an early 16mm home movie color process that used filters to record additive
color on black and white lenticular film. The only way to view the
color was to project the film with a similar filter on the lens.

Around twenty years ago, before the internet, I found a World Book Encyclopedia loose-leaf Annual
binder with Annuals 1927 through 1931 at an antique shop for $2. Articles
in the '28 edition covered items such as the original Kodacolor process as
well as the "new" invention of talking motion pictures. It was my first introduction
to this mysterious, obsolete color format.
Several years later I lucked upon a working Kodascope Model B 16mm projector
that included a Kodacolor filter and thanks to a new a scanner and digital
camera, this and other stuff are on the internet for the first time.
So far, I haven't found an example of Kodacolor film to project but am
still looking for some. If you have any to spare I may be interested.

MOVING PICTURES IN COLOR IN THE HOME.
Movies in full natural colors, taken in your own home, are now possible.
The only apparatus required is a special film and a plain color screen divided
into red, green, and blue sections. This is placed in front of the lens of
the movie camera.
Simple though it seems, it took years of experimentation on the part of
research engineers of the Eastman Kodak Company, Rochester, N. Y., and the
outlay of vast sums of money, before the dream of George Eastman, veteran
inventor of cameras and photographic apparatus, became an actuality.
The first really successful home movies in natural colors were shown on
July 30, 1928, on a screen at the residence of Mr. Eastman, in Rochester,
before a group of distinguished scientists and public men, among them Thomas
Edison, inventor of moving pictures.
GEORGE EASTMAN DEMONSTRATES KODACOLOR
PROCESS TO THOMAS EDISON
Inset - Color filter lens which makes lt possible to take moving: pictures
in full colors in the home.
DIAGRAM OF COLOR SCREEN.
The rays from the three-fllter colors are laid on the sensitive emulsion
by minute embossed lenses as one, or two, or three distinct impressions,
according to the color being reflected to that point.
The Process. For many years
the work of perfecting color movies had been carried on in the Eastman research
laboratories under the direction of Dr. C. E. Kenneth Mees, The new process-Kodacolor
by name-is said to rank in importance with the discovery of film and the
invention of moving pictures.
The amateur photographer's part is very easy. He has merely to insert
a color filter into the lens and thread the film in his camera. The most
radically new element in the process is this film. Instead of having the
usual smooth surface, the side opposite the sensitive coating is embossed
with cylindrical lenses so minute as to be invisible. The lenses, which are
part of the film itself and made of the film substance, would each look,
vastly magnified, like a rib of a corrugated iron roof. They run lengthwise
of the film and the width of 559 occupies an inch.
The effect of these invisibly small lenses is to separate the rays of
light coming through the three segments of a three-colored light filter
into the camera. Each of the three colors of the filter -red, green, and
blue- lets into the camera from the scene in front of the camera only the
light rays of its own color. The three different colored light rays register
on the film only as black and white; but each tiny lens embossed on the film
so distributes the light rays falling upon it that the various colors register
on the sensitive film emulsion as a distinct black and white impression for
each color at that point.
The light of the projector then passes through the film in such a way
that it shines out through the tiny film lenses, and then through the projector
lens; and each ray is directed through the proper color on the light filter,
to fall on its proper spot on the screen. The combination of the three colors,
red, green, and blue, gives every
possible natural tint.
