Color Print Developing
Time Cut; to IS Minutes
New Process of High Value
For Air Reconnaissance

Time required for developing and
printing color film has been cut from
approximately 18O to IS minutes in a
new process developed for the Air Force.
Color photographs are much better
than black -and-white for camoufage de-
lection and general Interpretation, and
the new process. worked out by the
General Analine and Film Corp. Of Bing-
hamton, n. Y. Is expected to be of i'm
measurable value for future air recon.
naiSsance.
The process, Photographic laboratory
engineers at Wright Field point out, will
very largely eliminate the lag which now
exists between the time a picture Is
taken by recon crew and the time it
is ready for tactical use.
Available to Services.
For the time being the process will be
available only to the services, but even
tually it will be released to the public.
Thus far color quality resulting from
the new process has shown itself to be
equal to, or even better than, that
achieved in normal processing methods.
Basis of the new method Is a prehar-
dener which permits the processing to be
done at degrees Fahrenheit instead of
the SO to 10 degrees Fahrenheit nee
essary for the normal process. The
hardener prevents the emulsion from
becoming too soft at this higher temper
ature. ..
1t is expected, according to an Air
Force announcement, that the new
method of processing will be standardized
in service tests to be conducted at vari-
GUS bases. At present the supply of new
kits necessary for the process is
limited, and it will be necessary to train
field laboratory units in the new tech
niques.
The method is looked on as one Of
the major advances in air reconnaissance
since the end of the war In many
respects the art was still elementary dur
ing actual combat operations.
The Milky Way galaxy, which COM
prises all the visible heavens and con-
tains about one billion stars Of all classes,
is one of family Of 16.
Finding Of two other members of the
family of galaxies In this part Of space
has just been reported by Drs. r. G.
Harrington and H. G. Wilson Of the Mt.
Palomar observatory. Both are in the
direction of the constellation of Leo in
the northern heavens. At the best they
are extremely faint objects. hitherto
escaping detection in the most powerful
telescopes. Once they were located, how
ever, it was possible to discriminate over
200 of the brightest objects in each.
Although undoubtedly members of the
local family of galaxies, they are so dis
tant from the edges of the Milky Way
galaxy that it requires their light, NOV
ing at 10000 miles a second, approxi-
mately 650,000 years to reach the earth.
Small as Galaxies.
Both are small, as galaxies go. Their
diameters are only about 10000, 900 ,000,-
100000 miles. They also differ from the
Milky Way galaxies in being elliptical and
with having an even distribution IF stars.
There is no evidence of the spiral struc-
ture whirling around nucleus, as is the
case with this galaxy and the great An
. dromeda galaxy, which was the first such
object TO be identified about Is years
ago. They may be more comparable to
the Clouds of Magellan in the far SOUTH
ern skies and possibly are younger OBJ
jects than the Milky Way galaxy.
The Milky Way family consists of those
galaxies within about a million light years
of each other. 1t is estimated that there
are close to 100 million within 500 million
light years radius and the number in
creation presumably will approach in
finity.
