HE SHOWS
A MARVEL
Color Photography Is
a Reality.
DR., A, P. PECK'S PICTURES
Distinguished Medical Missionary Of
China Explains the
Phenomena.

gational Mission hospital in Shantung
Province and for twenty years a resi-
dent of the Celestial Empire, is carry
ing back with him to China a process of
color photography which will enable
him to take photographs in any part
go to be mounted apd have the same
colors which he saw reproduced exactly
in the prints.
Startling developments have been
made in color photography in the past
few years and 1t has now become so
simple of manipulation that the anna
teur photographer is enabled to take
photographs by the process which Or.
Peck has and reproduce the colors or
landscapes, trees, persons and the ever
changing hues of the ocean exactly as
they are to the naked eye.
Dr. Peck last evening displayed to
an Advertiser representative many OF
the photographs he had taken by this
process showing colors with vividness
which is startling when 1T is known
that neither the brush of an artist nor
the paints upon his palette have had
ANYTHING to do in bringing them out so
NN'N
a few days since took of the judiciary
building Is fine specimen OF this new
art. The positive is itself like any other
pIate-merely showing black and white
with a color screen placed over it and
adjusted to a nicely every hue in the
building, the grass plots, the gilt on
the statue of the martial kamehameha,
are clearly brought out.

pher" said DIR. Peck. "Ths process
was discovered in Chicago by gentle
man named Mcdonald. He was not a
professional Extraordinarily an am
ateur. He accumulated fortune in
business and he spent his last years
and considerable of his fortune in ex-
perimenting on this process. 1t was
not an accidental discovery.
There is but a single exposure. Neg
atives are taken in an ordinary camera
through glass screens which are
grooved with lines not entirely visible
to the eve There are 800 to the inch
or about 1900 to a plate. The lines are
made by machines, automatically ad-
justed. The ruling is done with deli
cacy hardly to be explained. The lines
are made by lines of agate and carne-
liam. There is no space between the
ruling so that no white light can get in.
The machine is enclosed in glass case
and does it's work automatically.
1.-The primary colors are to be seen
in rainbows on these screens If placed
in the light properly. These are red,
blue and green. Yellow used to be
thought one of the primary colors. but
it is not.
"a camera is fitted with a taking
screen, which is fixture, behind
which any number of photographs can
be taken. The platehOlders are slipped
in behind the screen and an exposure
is made for fifteen seconds. The light
is analysed by this screen as the pho
tograph is taken in on the negative.
When the positive is taken from the
negative the primary colors are in the
black and white reproduction, but not
visible of course. Now take one of
these screens and adjust it over the
picture and you have the colors repro
duced. The adjustment of the screens
over the positives is a matter of nice
manipulation and I prefer to send my
positiVes to Chicago"
DIR. Peck illustrated his meaning by
placing a screen over many positives
he had. The rainbow colors fared out,
became small streaks, and finally as
simulated themselves with those of the
positive and the color scheme was COM
plete
"These photographs can be reproduce
ed in color half tones as we'll" said DIR.
Peck. zone of the most beautiful
features of this discovery will be the re-
production of photographs for maya
zines and books. Here, for instance, is
a photograph of a piece of embroidery
work-fowers. An ordinary copper
plate was made for this. The negative
is taken on the copper plate and then
etched with acid. Then in press work
with a single impression of black ink
every color in that embroidery work
was brought out. In Chicago they are
now constructing a four cylinder press
for color work the printing of which is
all done with black ink.
1.-THE scientific world will profit by
the discovery as photographs in surg
cry can be made and reproduced In the
colors, with the flesh tints exact. In
astronomical work IL will be the same.
The spectra of the stars are studied
and by this process. the colors of the
spectrum can be reproduced exactly"
It's value to pictorial magazines can
he easily understood when by using
cameras adjusted with the color
screens the posltives can be sent In
from any part of the world and repro
duced upon their pages In the same coll
ors which the photographer saw In
taking the negative,
