TAKE PHOTOGRAPHS
IN NATURAL COLOR
Device Used In "Hichrography''
on Exhibit in New York,
Shows Remarkable Results.

NEW YORK. Sept. IA device for
making photographs In their natural
color, so simple that It's future both for
amateur and professional work Is
assured, has been perfected by Fred
erick e. Ives and Is being demonstrated
for the first time at Wanamaker's. The
invention Of Mr.. Ives replaces the old
method whereby the color work sufficed
only for transparencies and a single
picture was obtained for each sitting.
With the new method the colored
photographs can be finished UP like any
other picture and as many prints as
As demonstrated by Wilbur G. Smith.
Of the Hess-Ives Company, which
makes the cameras and needed sup
plies. the color photography can be
done by any amateur who Is old
special camera is necessary, but the
task Of taking and developing the pic
ture. while more expensive than the
old method, Is no more difficult.
Is Called "Hicro."
The special camera. which Is called
the "Hicro," Is loaded with a pack
holding three plates. When the object
has been focused the slide Is removed
from the plateholder just as in the or
dinary camera. One Of the plates falls
forward, but the others are kept In
place. A lever is then moved which
throws q yellow screen over the plate
which has fallen forward on to the
floor Of the camera. This screen picks
out the blue rays and throws them onto
the first plate. y.
The other primary rays. yellow and
red, 70 through the screen to the other
two plates. One of these registers the
image with the red rays emphasized.
the other with the yellow rays. The

giving the same image. Prints are
then made from the plates by the
| ordinary exposure to the sun. The
emphasized the blue rays Is printed on
blue print paper. while the other prints
are made on sensitized celluloid. as or
a film.
Shows Faint Image.
| When the prints are developed the
blue print shows like any other blue
print. The prints from the red and
yellow plates show only q faint image
on the celluloid. These are then placed
in a coloring bath which dyes them
the print from the red plate in red
bath and that from the yellow in q
| yellow bath. These prints are ther
superimposed upon the blue print: thu
red first and the yellow on top. They
can then be trimmed. fastened In posi-
ton with a bit of cement and then put
through a wringer to be sure they arc
| absolutely smooth.
Since blue. red. and yellow wher
blended give the other colors. It cal
be understood how all the original col
ors are brought out in the finished
picture. Tho many who viewed tn,

simplicity of the method and the ex
cellent results accomplished. A repro
duction of an oil painting was so vel
done that the photograph has all th
earmarks Of an original in miniature
One value of this method Is that tn,
