chambers. The "APEM " spool holders (Fii. 3)
are hinged to the Camera and can be swung out
for loading the film and to remove the spool-after
exposure. It will be noted that the bottom spool
holder is fitted with t\^'o pegs, these to hold'the

FOCUSSING.
When the tront is at infinity it is in the
position at which most views are taken. For near
objects it is necessary.to focus. On the rieht
hand side of the Camera baseboard there is" a
scaleengraved for various distances-6, 10, lp^1ng
100 feet (Fis. 7). This
servesas an infinity catch,II and automatically srops
the front carrying the lens
and shutter at the correct
focus for landscapes,srreer
scenes, etc. FoF nearer
objects, suph as groups
and portraits, the front is
released and drawn for-
ward until it engagesin i
the position opposite the
distance desireo.
THE VIEW FINDER.
The "APEM " is fitted with a brilhant Finder
for locating the object to be photographed. Point
the Camera at the object, viewing it in the Finder.
The image shown in the Finder will be the image
impressedon the actual film. In taking a picture
the oblong way of
the film the Finder
is turned a full
quarter of a circle '
to the left (Fig. 8). I

the speed,revolvethe ring until the speedrequired
!s gpposite the pointer on the top oT the shutter.
When the pointer is oppositethe letter B, what is
known as a "Bulb" eiposure may be given. A
single pressureon the releaseA opens t6e shutter,
whrch r,r'ill remain open until the pressure is
removed.. When the pointer is oppositethe letter
T, a time ex.posuremay be given. On pressing
the.release,th9 shutter opens, and renrainsopen
until a second pressure-plate is given, when it cloies.
The engraved on tfi'e top of the shutter
is fo1 the purposeof regulating the size of the Iris
diaphragms. f'he Cameras_fit1ed with anastigmat
len.seshave the General Shutter (Fig. 11). Ttrit
giv-esa more complete range of speedadjustment,and exposures of +, +o, -*s, sLoand a$6 sec. are 1
possiblein addition to the Time and Bulb.
CABLE RELEASE. f'his is a flexible wire releasewhich is screwed d!
intc,--the-aperture (B) on the side-of shutrer, and {used in place of the trigger release. It is recom-
mended as the bestmeansof giving time and bulb
exposures,par_ticularlywhen the Camera is resting
on a table or fixed to a tripod.
THE LENS.
l'he lens fitted to an "APEM " Camera is the
best possible at the price. Each is tested, and
will give clean,crisp picturessparklingwith detail.
There are advantages in having an Anastigmat
lens-it is faster and permits pictures to be tiken
in dull light. T'he Rapid Reciilinear is faster than
the single Achromatic though not so fast as the
Anastigmat. Used judiciously,-'Theeachtype is capable
of giving excelleni results. Irii diaphiagm
controls the amount of light passingthrough ihe
lens to the plate. The first number (or lowest)
on the scale is the full opening; the next larger
number indicates that the lens opening has been
reduced one half, thereby necessitatingdouble the
length of exposure and so on.View original page 10Page 12 · Read text

window, give the winder five or six turns and then
removethe back; hold the paper taut so as to wind
tightly, turn the key until the paper is all on the
reel; on the empty spool r,r,illbe found a strip of
gummed pa-per, use this for sealing the spool.
Swing the spool holder out of the Camera, pull
the winder outu'ards and reirrove the comoleted
spool. f'ake the supply spool, transfer it io the/ winding chamber engaging the winder kev, then
give a few turns to make sureeverything is working
properly. Reload with a new spool as before
described
MAKING THE EXPOSURE. .1
1
Successin making exposures depends on the t
right understanding and use of the finder, lens,
and shutter. The rapiditv r,r,'ith'which the picture
is taken must varv accordingto the amount of light
available, the nature of the object, and the size of the lens opening used. t5{
As a guide the exposurechart marked out for
use with Rajar or "APnM" Roll Film will be
found most useful-
These exposuresare calculatedfor the months
June, July and August, on a bright sunny day
betr,t'eenthe hours of I I a.m. and 3 p.m., using
F7.7. The exposureshould be doubled if the sun
is obscuredor if stop F 11 is used. For F 16 give
four times the exposure. For F 5.6 give half.
From 9 to 1l a.m. or from 3 to 5 p.m. double
these exposures. From 7 to 9 a.m. or from 5 to \ 7 p.^.increase them three or four times.
;&&, During all exposures the Camera should be
held stcady. Movement will produce a blurred
picture. For time exposures the Camera should
rest on a firm baseand the leg support (FiS .12) in
i
s{ front should be turned downr,r'ardsas far as it
will go.
