PHOTOGRAPHIC CAMERA.


Suppose, now, where the bright spot strikes
the floor, you should place plate Of glass,
prepared in a certain way. SO that it would
retain the image which came through tn
hole in the curtain. Instead Of the mere sun
light, have an object on which the light fall
in such q way that rays from it would stream
through the curtain. The image would be
caught and held by the glass, so that it would
remain after the glass was removed. There
you have photography. You see the little dark
chamber IN the Illustration, with the sensitive
glass plate at the back and the image upon
it. A glass lens is fixed into the aperture Of
the camera. The glass is prepared by spread
ing upon it certain chemicals that are acted
on by the light. They are therefore called
sensitive" and the plate thus prepared Is
called a sensitive plate. The salts or chem
icals are contained in gelatin film which is
spread upon the glass. Tho sensitive plates,
however, come already prepared in the out
fit, so that the amateur will have no trouble
with them. The next step is called
DEVELOPING THE PICTURE.
When first removed from the camera the
glass plate shows no image upon its surface.
1t must be Immediately put into dark place,
Lit only by red light, and plunged into
chemical bath. That brings the picture out;
how, will be explained in the little book.
The red rays are the only light that does not
affect the sensitive salts upon the plate.
Next it must be printed. That, too, the
book will tell you how to do. By following
directions carefully. in n little while you will
be able TO take photograph of your baby,
your COW or your mother-in-law. Fine por-
tra:: photographs, however, must always he

photographs. A gentleman known to the
writer hereof became interested in amateur
photography about two months ago, and he
has already become so expert as to he able
to take instantaneous views from his office
window Many ladies have become fasci-
mated with photography. too, and some take
really excellent pictures. There are light
cases containing all the implements necessary,
SO light that woman or n schoolgirl can
carry one Of them. Cliffs, trees, picturesque
landscapes, q flower, a dinner table or an
artistic costume may be photographed in a
moment. 1t is a far more fascinating and
bealthful amusement than rick-rack making.
Photographers now accompany all survey
ing parties and exploring expeditions Pho
Biography has added new power both TO
science and to art.
INSTANTANEOUS PHOTOGRAPHY.
Nothing more curious and interesting has
been discovered in half century than this.
Artists have i'm vain endeavored to catch
with the eye and reproduce with the pencil
the positions Of animals in rapid motion
such as q horse running race. The speed
was so great that it could not be done satis-
factorily. Now, however, comes In the in
Simultaneous sun picture and the thing is &C
complished. By this process the amateur
will be able to open his little dark chamber
upon anybody, however unsuspecting and
catch his face.
Below are some views reproduced from iu-
Simultaneous photographs.
