   To Open Camera.  Press dorvn the catch B
and pull down the baseboard till  it  is at right
angles with body, when the side struts will slip
into catches. The lens front can then be pulled
out by means of the thumb-pieces J, one of
rvhich will  spring into a notch when  it  is in
right position.
   The Lens is an Aldis Uno Anastigmat of
superb quality.    It consists of three different
lenses, rvhich  in  combination  are perfectly
             corrected, and  all the defects in-
             cidental to Single and Rectilinear
           Lenses are absent.  Not only will
                       it  rvork much  quicker,  bui  the
             pictures are sharper and exqui-
              sitely defined.

the lens a series of metal plates will be seen

they are made to open or close, so as to increase
or  diminish  the aperture through which the
light passesto the film.

indicate a definite size of opening in relation to
the  focus  of  the  lens  to  enable accurate
exposuresto be estimated.

   The use of the various apertures is referred
to on page r r but   it  will  be apparent that as
the light reflected from the objects must pass
through the diaphragm, the smaller the aper-
ture, the less the amount of light that can pass

rneasure or marked tape on  the ground and
learn to judge by comparison, and one will soon
become familiar.   Extreme accuracy is un-

'fhe         General Instructions  tor  Exposing.
          first attempts should be made orit of doors in
      good light  with  the shutter set at 5o and the
       lens_atflZ'2.  Make two exposures-diaphragmunder these
       con-ditions, then close the               to -f-fltt
      and make another two ; again-close it to  116
      an-dexpose the last two sections of the spool.
       After development the  film  will  serve as an
      example of the difference made in exposures by
       using different sizes of diaphragms, and  rviil
      save wasting many films.
         There is a great deal of latitude with  films,
      and for snap-shots in good light the diaphragm
       p-ointer can generally be placed at f lu  ind  ihe
       shutter speed at 5o.  In weak light and in the
       winter months,                          flZ'Z  will  usually be necessary
       with the shutter set at 25.t           Interiors.  Quite a different set of conditions
       arise, and a few experiments may be necessary
       before certain sucCess is achieved.  The ex-
      posures vajy  from  one second up  to manyi
       minutes.  The shutter should be set at T and
       the lens at flfi,  and then  for a well-lighted
      room in summer at mid-day the exposure will
      approximately be ro seconds. Secohds of time
      calculated by saying rapidly ,,r.2-r.2," which
         is one second, or long eiposures may be made
      by means of a watch witli seconds dial.

To Unload Camera.    After  last exposUr€r
rvind the film on to the receiving roll as far as
possible, and until by the free manner in which
the key turns one is certain all the black cover-
ing paper is rolled over  it.  Open the back as
before and a  strip  of gummed paper  will be
found with which  to secure the exposed film.
The spool key E can then be raised op and the
exposed 6lm taken out.

f-plate Deep China Dishes (one for developing,
one  for   fixing) ,  8-oz.  Everseen  Measure,

                      The Developer and
                  Hypo must be dissolved
                           in accordance with  the
                       printed instructions. An          .i

                     unnecessary;  develop-
                   mgnt may be conducted
                           in any room  that can
                    be made dark. The onlv
                      permissible light  muit
be from a Ruby or Dark Orange lamp.  Special
globes are supllied to fit over Electric Buibs.


                         www.orphancameras.com

Put  Trident  in the dish flat side up, and
use plenty of developer to cover it.   Carefully
unroll the spool and take away black paper ;
hold one end of film  in each hand,  film side
down and as rapidly as possible immerse in the
dish of developer, pushing it under the centre
finger of the Trident, beginning at one end and
drawing the film through until  it is quite cover-
ed.    It  is important to seethc deuelofcr f,ows euenly
oitcythefil*,  or ncnrhsruill result and st'oil thenega-
tiue.  Continue to move  it backwards and for-
wards in the developer until the image begins to
appear. Up to this stage it should be kept well
alvay from the direct light  of the lamp.  Con-
tinue the development untii the image appears
well through on  the bacii of the film.  This
should takefrom 4 to ro minutes, according to the
temperature ;  it takes longer if the room is cold.
The film must then be placed in the  " fixing,"
and the bath allorved to act until  all traces of
the creamy emulsion have disappeared and it is
quite clean in the shaclows.  It should then be
washed in running water or frequent changes
for not less than half an hour.  To  dty  pin   it

rvards cnt apart into separatepicturer.

IIow to make a Print.  For  this purpose, a
printing  frame, a packet of self-toning paper,
and some Hypo  for  fixing  will be required.
Place the negative in the printing frame which
must be provided with  a sheet of glass, film
side upwards, and  l*y  on   it  a sheet of the
printing paper, replace the back of the frame.
As the paper is not so -"ensitiveas a film, print-
irg  and fixing may be carried out in ordinary
daylight, but  not  in strong sunlight.   After
loading, place the printing frame in a strong
diffused light, and watch  the print  carefully
from time  to time by opening one-half of the
printing frame.   Print  until  the image  is a
LITTLE DARKERthan is desired.
   Having made the prints, they must now be
fixed, otherwise they  will  fade.  Take all the
prints that are ready and wash them  for a few
minutes in several changes of water, and then
place one by one in the fixing bath.  This must

not be the same bath  that was used for the
 films, but must be a quite  fresh one, not so
strong, only 2 oz. to the pint of water.
   Leave them in the " fixing "  for about ro to
r5 minutes, when they should be again care-
fully taken out separately and washed in either
running water or many changes of clear water
so as to wash out  all the Hypo.  They may
then be laid aside on blotting paper or pinned
up to dry.

the " Watch Pocket Carbine,"  is zlxzft  in. but
by the aid of the enlarger shown on the back
page,       |-plate prints can be made.  This is quite
a simple process. The negative is placed in one
end, and a piece of                     {-plate Bromide paper in the
larger end; and then exposed to daylight  for a
few moments.  The Bromide  paper  is then
developed and fixed according to the instruc-
tions which accompany each packet of paper.
