Daguerre didn't know it, but he had secured his uict
probably in everyone of his hundred experiments. hue
he lacked the secret Of the developer Chemical act;n
was necessary to bring the picture forth to view
There have the beginning OF photography; born
of, not for, moving pictures
THIS first picture died an early death When il w..
brought to the light, it folded its tent like the ArsI
and as silently faded away. Dagucrre held the mos,
beautiful the most sensational thing in the world in he
hand for a few minutes, and then 1t became an ugly
backcncd plate He tried all Of things TO FIX h.
next pictures Common salt in water proved to be the
most likely that he hit on; but the science OF photogranb
as Dagucrrc discovered it amounted to much until
crSchcl the astronomer suggested "hypo, and since
that suggestion photographers have never found any,
thing better
It is interesting to trace the stages Of the science
following DagucrrcS accidental discovery when looking
for an easy way to provide scenery for his moving pic
turc emporium. The French nation Rugged the scene
painter to its bosom. The wonderful discovery was
Chroniccd far and wide, and the French Chamber Of
Deputies met and voted the inventor life pension Of
six thousand francs, and his collaboration lsdore Nepoe
son Of Dagucrrc first partner four thousand francs on
condition that the discovery be published and pat.
cntcd Dagucrrc cannily slipped across to England and
patented the process there. In some large towns in
England as much one thousand pounds paid for
the exclusive right the process 50 Dagucrre profit
cd beyond the dreams OF his now forgotten diorama
Arago his friend, brought the discovery before the
Academy of Sciences in Paris in 1899, and the action Of
the French Government followed Immediately. Arago
addressed the Chamber Of Deputies, saying:
at requires no knowledge Of drawing and does not
depend on manual dcXtcrity. The prompttudc Of the
method is perhaps that which has most astonished the
public. In reality, ten or twelve minutes IN the dull
weather of winter are amply sufficient for taking view
Of a monument a section Of a town a landscape In
summertime this may be reduced onchait. Under the
skies Of the south not than two three minutes
will be necessary.
Arago went on to say that to this time must be added
the time spent in packing and unpackng the camera
and in the manpulatlons necessary to develop and fix
the picture.
"fhose persons are deceived, then, he warned the
DEPUTIES "WhO suppose that during journey they
may avail themselves Of brief intervals while the carriage
slowly mounts hill, 20 take views OF the country
PHOTOGRAPHY today, with the aid Of the 50 called
focal plane shutter takes pictures IN rs little as one

views Of the country while the position Is pushing his
tired stceds up HILL However, It has been long hard
road that makes the moving picture Of today possible
By the way the discovery Of Dagucrre pu, the good
old dorama So far i'm the background Of public interest
that it died natural DEATH and never prol.eI by the
birth of its brilliant child.
The first step toward the millennium in Photography
was the substitution Of bromide for iodine In picking
the silver plate This reduced the time Of exposure 70
something ike ten seconds. Then came p.r.rature.
But even at that, only picture could be made at
time and no duplicates printed from Il.
MI the time the diorama scene painter working
in secret there was an Englishman, Fox Talbot quietly
nursing along the germ OF discovery He had more
knowledge Of chemistry than had Dagucrrc. And he
was working on another tack. He was coating paper
with salts Of silver and exposing in camer % make
negatives; and like Dagucrrc, he got nothing but
trouble out Of his pains until he too 5ccam. victim
