COLOR PHOTOGRAPHY
SUCCESSFULLY TESTED
NEW INVENTION TRIED OUT IN
BURLINGTON, VT.
Delicate Shades Are Truly Produced
on Plates, Much to the De-
light of the
Artist

BURLINGTON, VT, Aug. 1.-THE first
raphy ever conducted in me United
States was made in Burlington this
week. Three of the newly invented
plates capable of this work were re-
ceived by Capt. Claudius Poulaillon,
manager of the Lumiere company of
America, from the factory of the Luz
miere Bros, Lyons, France, and they
were exposed by F. M. Steadman, a
professional photographer of Mexico,
the result being three superb photo
graphic successes.
The first plate was used to photograph
the entrance of one of the city's fine
residences taking in a portion of the
lawn and a mass of vines roses and
other flowers about the door. Each de-
tail was brought out in striking dis
tlnctness and with great accuracy of
color. The other two plates We're en-
ployed in a portrait. The niece of, Capt.
Poulallion was the subject. Included in
the portrait was a mass of flowers of
varied hue. The tints were perfect in
the reproduction, as was also the deli
cate color of her gown, but still more
wonderful was the faithfulness to the
living image in the hair and the perfect
With this new invention the sunset
and all the beauties of nature have been
placed within the reach of the artist
| M. Poulaillon, Mr.. Steadman and all
artists who have seen the pictures are
enthusiastic over results. The greater
task in this long-looked-for departure
has been accomplished, but one obstacle
still remains-the transposition of the
photograph to paper. At present the

The Burlington plant of the Lumiere
brothers, located at Lakeside, was es-
tablished but few years ago. Capt.
Poulaillon, then in the engineering
corps of the French army, resigned his
commission to accept the management
of it. 1t is their only factory in the
United States. Capt Pouaillon is a grad
uate of rEcole Polytechnic and pro-
found student of science. He is of the
opinion that the manufacture of the col
or plates will be commenced here within
year, possibly in a much shorter time.
The means by which the color effect
is given to a plate is not so complex as
might be imagined. Potato starch is
separated into minute particles and divid-
edtinto three lots. These are dyed violet,
green and red, the extreme and middle
are spread upon the glass by a process
which allows no interspaces, neither per-
mits the colors to run; then a thin var
pish of about the same retroactive index
as that of the starch grains is applied,
and finally the film of sensitive pancro-
matte emulsion of silver bromide coats
the plate.
The plate is exposed in a common
camera but in a reverse order, the rays
first passing through the glass. The light
rays traversing through the fundamental
screens suffer a variable absorption, and
thus is realized a selection by micro
scopic elements which enables the col
ored images to be obtained, the colors
being Complementary to the original.
Development Is effects as in the or
binary photograph, and by simple
chemical treatment the order of colors
is reversed, giving a positive instead of
negative image. In the exposure a yell
low screen Is interposed to compensate
for the excessive activity of the violet
and blue rays The absorption due to the
iuterposition of the colored elements ne
cessitates a somewhat longer exposure
than usual, still it s possible to ATTAIN
results in sunshine in one-fifth of a sec
ond with the lens working at f-3
The simplicity of the process is borne
out by the fact that Mr. Steadman was
successful in his first attempt; notwith-
standing the fact that he had never seen
the operation executed or made any ex-
tensive study OF the subject, his expert
ence with ordinary photography and a
little extra care producing perfect pic
lures with the three plates.
