this being easily managed by means of
the gummed paper guides. Finally, ex-
pose the plate which has already been
used to photograph the bottle; and when
this is developed your friend will duly
appear-inside.
This method will be found in practice
to explain many pictures which at first
seem very astonishing. To make q
vision fake arrange little scene, such
as q bare room with an empty hearth.
with your model sitting lstlessly in the
foreground. Make your first exposure on
this scene, being careful to mark out on
the ground glass screen the space into
which the vision must fall. A dark cur
tain. or dark woodwork, should occupy
this space In the first picture. Now pro-
cure a sheet OF dead black paper, mount
1t evenly upon stiff card, and with a lit
tie Chonese white sketch out an ap-
propriate vision If you cannot do this
yourself, get an artist friend to help you;
but see that the sketch is placed in the
correct spot, /. e., the spot which you
have arranged for it to occupy in the tn-
ished picture When the sketch is fin
ished, set it UP before the camera, focus
and see that it falls within the required
boundary upon the screen. Then expose
again the plate which has already lone
duty, and-if no miscalculations have
been made-an interesting vision" pic
ture will result similar to that which is
here reproduced.
The ghost fake" may be made in ex-
actly the same way, only in this case
an appropriate scene would be a deserted
churchyard, with your model posing in
an awestruck attitude beside a tomb.
In all photographs of this kind the read
er should bear in mind that dead black
background does not appreciably affect
the sensitized plate, but show plate
should be used whenever this is possible
as by this means any slight tendency to
fog will be obviated.
On the whole, however ghosts and
vision photographs are best and most
realistic when made in the following
way. Get your model to sit or stand In
a particular place for about second
while you are exposing; then cap the lens,
and let the model walk away from before
the camera. Now expose again for two
or three seconds more, and on developing
the negative there will appear a faint
image of the model with the objects be-
hind seen through his or her body.
If you drape white sheet over your
models head and shoulders the effect
will be all the more ghostlilxe; while you
may make your ghost appear to be ad-
dressing warning to some one sitting
at a table, or otherwise engaged. While
dealing with this subject it may be useful
to add that a little sulphate of quinine,
| say about a quarter of an ounce, dis
solved in a pint of water to which lit
| tie sulphuric acid has been added, pro-
vides a paint which, while invisible to
| the eye, effects a Photographic plate.
| Thus any figure or words may be painted
upon a dark background and allowed to
| dry. The marks will be invisible, yet
| they will appear quite distinct on a Mega
| tive, and be a source of no small wonder
| to those who are not in the secret.
| Such photographs as seem to show a
lady face to face with herself. or playing
| a game of cards with herself, are very
astonishing at first glance. Yet they
| are very easy to produce. Just inside the
camera as close as ossible to the grooves
| into which the dark slide is placed,
should be fitted a thin metal plate, duly
blackened to prevent halation. This met
al plate should exactly cover one half of
/ the plate when the latter is exposed.
The model must now be posed swell to
one side of the picture, so that her body
| Is seen on one half of the focusing
screen which is uncovered by the metal
plate. After focusing the plate holder
should be inserted and the exposure
made in the ordinary way. Then. after
removing the dark slide, the metal plate
should be moved so that it covers the
other half of the plate, and the sitter
also move over to the other side OF the
picture. A little thought and ingenuity
will enable the photographer to pose his
mcdel and stage his picture effectively.
! On developing such negative the same
person will be shown in two positions;
and If the metal plate has been carefully
made and blackened there will be abso-
lutely no trace of join. BY having sew
era metal plates insteAd of one, and
moving them about as required, the model
may be made to appear three or four
times upon the same negative.
| Another way of obtaining this paticu-
lar kind of freak photograph is to fit a
tube in front of the lens Instead of u.s.
ling a cap, the tube should be closed with
a kind of folding door arrangement, so
that one half of the lens may be un-
covered at a time. A still more simple
plan is to use a cap which coters only
one half the aperture and to control the
exposure by means of a shutter behind
the lens. This method, however, makes
| it necessary to "stop down" the lens to
at least 1-3, and a long exposure is thus
rendered inevitable
| 1t is well known that the nearer an
object is to the camera the larger it
appears to be in proportion to other OBJ
| jects in the picture and by taking adj
vantage of this fact some astonishing
pictures may be obtained, particularly IL
| a lens of somewhat short focus is en-
/ reproduced in a popular magazine a
photograph which was described in all
seriousness as depicting cabbage of gf-
| gantic proportions Doubtless most peo-
pie who looked at the picture were de-
ceived. for the cabbage partially OBJ
scured a whole family of FIVE or six per-
sons who stood somewhat In the back
ground. Yet in reality the Vegetable was
OF only ordinary proportions, and merely
looked large in proportion to the human
| beings because of it's nearness to a lens
of short focus In the same way. If a
! fisherman has caught fish six inches
long 1t may be made to appear gigantic
In the photograph. BY means OF his rod
and line the fisherman may hang his fish
a good six or eight feet nearer the CAM
era than he himself is, and the lens
does the rest.
Very laughable caricature photographs
may be made by simply moving the
swing back" of the camera ont of the
perpendicular. Your friends may he
made to look like reclining giants. or
