Successful Experiment in Color

OBSERVATION-DISCLOSURES Unable at Pres
ent to Transfer the Color Pictures.
The first successful experiment in color
photography ever conducted in the United
states was made in burlington last week.
Three of the newly invented plates cap
able OF this work were received by Capt
ClauuIus Poulaillon, manager of the Luz
miere company of America, from the fac
tory of the Bumiere Brothers, Lyons,
France, and they were exposed by f. M
Steadman, a professional photographer
of Mexico the result being three superb
Photographic successes.
The first plate was used to pho
tograph the entrance of one of the
city's fine residences, taking in por-
ton Of the lawn and "A mass of vines,
roses and other flowers about the door.
Each detail was brought out in striking
distinctness and with great accuracy of
color. The other two plates were en-
ployed in a portrait. The niece of Capt.
Pouaillon was the subject. Included in
the portrait was a mass of flowers in
varied hue. The tiuts were perfect in
the reproduction, as was also the delicate
color of her gown, but still more wonder
full was the faithfulness to the living
image in the hair and the perfect shading
in the face.
with this new invention the sunset
and all the beauties Of nature have been
placed within the reach of the artist.
Mr.. PouaillOn Mr.. Steadman and all
artists who have seen the pictures are
enthusiastic over results. The greater
task in this long looked for departure
has beer accomplished but one obstacle
still remains-the transposition of the
photograph to paper. At present the
photographer is able only to create the
color picture on the plate, a transparency
The Burlington plant of Lumiere Broth
ers at Lakeside was established a few
years ago. Capt Poulailon, then in the
engineering corps of the French army
resigned his commission to accept the
management of it. 1t is their only fac
tory in the United States. Capt. Pou-
laillon is a graduate of L'Ecole Polytech'
niQue and a student of science. He Is
of the opinion that the manufacture
of the color plates will be begun in Bur
lngton within a year
The means by which the color effec
is given to a plate is not so complex as
might be imagined Potato starch 1!
separated into minute particles and di
Vided into three lots These are dyed
violet. green and red, the extreme anC
middle points in the color scale. These
particles are spread upon the glass by {
process which allows no interspaces
neither permits the COlors to run; tner
thin varnish Of about the same refrac
tive index as that of the starch grains l.
applied, and finally the film of sensitive
pancromatic emulsion Of silver bromid,
coats the plate.
The plate is exposed in a common
camera, but in a reverse order the ray
first passing through the glass. Thu
light rays traversng the Fundamental
screen suffer a variable absorption, ant
thus is realized a selection by MICROSCOPE
elements Which enables the coloret
images to be obtained. the colors beinl
complimentary to the original.
Development is effected as in the or
binary photograph, and by a simple chem
ical treatment the order of colors Is re
versed, giving positive instead of
negative image. In the exposure a yellow
screen is interposed to compensate 70
the excessive activity of the violet an
blue rays. The absorption due to tn
interposition of the colored elements ne
cessitates a somewhat longer exposur
than usual. still it is possible to obtai
results in sunshine in one-fifth of
second with the lens working at f-3.
The simplicity of the process is born
out by the fact that Mr.. Steadman wa
successful in his first attempt, notwith
standing the fact that he had never see
the operation executed or made any ex
tensive study of subject. his expe
rience with ordinary photography and
little extra care producing perfect pic
lures with the three plates.
