    MINIATURE CAMERA



  The Korelle Reflex is tomorrow's comero mode avoiloble
todoy.  lt is years oheod of the photographic  field in design
ond occomplishment, embodying as it does all the desiroble
feotures of the better types of comeras, yet comprising o
mere hondful of precision photographic engineering.
  The Korelle Reflex comero produces twelve exposures,
each measuring 6x6cm. (21/cx21/4 in.) on o roll of stondord
No. 120 roll film.  The outside dimensions of the camero
proper ore as follows 51/zx3t/27Jt/2 in. (with the focusing
hood folded down). Mode of durolumin, leother covered,
this comero will withstond long ond hord service. The finest

interchongeoble  lens feoture, the Korelle Reflex stonds os o
supreme exomple of modern photogrophic ochievement-
o comero you will be proud to own ond use'


    AND HOW TO SECURE
       PERFECT RESULTS WITH IT

NOTE: Before.ottempting to use the Korelle Reflex, be
 sure to read the following instructions carefully in order ihot you moy secure o full understanding of the operation ond core of this splendid instrument.
     It must be understood thot o precision comero, such as
 the Korelle Reflex, is virtually on instrument of watch-like
 occurocy/ yet ruggedly buitt to stond hord service. Becouse
 of its precise assembly o_ certoin omount of core is required
 in handling ond use. You wouldn,t deliberately obirie o
 fine wotch or radio set, or outomobile-why not ilccoJ the
 Korelle Reflex the some core and ottention you would to
other finely mode instruments. Given reosonoble ond in-
 telligent core, this co_mero will perform beoutifully ond offernot the slightest difficulty.

         FOCUSING THE LENS
  The Korelle Ref lex uses o ref lecting mirror focusing ground
glass panel, ond this is occessible by lifting the focusing
hood cover (7) Fig. I ond permitting the other three sides
of the hood to soring into their position outomoticoll';.'.
These four metol shields constitute o serviceoble hood which
keeps light owoy from the ground gloss ponel, moking  it
eosier to focus ond compirse the picture. With the focusing
hood in its erected position you will see the imoge of your
picture, right side up, on the ground gloss focusing screen.
The imoge you see on the ground gloss is formed by the
lens thot tokes the picture. Whot you see in the hood you
get in the resulting picture. Porollox is eliminoted. There
is no displocement of the imoge to be ollowed for when
working close-up to your subiect. The ground gl9:s screenis locoted directly under the focusing hood cover (7) Fig.  I
when the lotter is closed. An ouxiliory "eye level" finder
 (8) Fig. I  is provided for oction photogrophy. This con-

  To focus ond compose the picture, it becomeS necessory
only to view it upon the ground gloss. To focus the lens,
slowly turn the knurled ring (12) Fig. I on the lens. Focus

        SETTING THE SHUTTER
   Before the exposure con be mode, there is one other mat-
ter to be attended                 .  the setting of the shutter
speed. The vorious speeds of the shutter will be found on
the shutter speed setting diol (5) Fig. l.     lf l/5Oth sec-
ond is indicoted os the correct shutter speed, lift the setting
diol (5 ) FiS. I ond turn it until the figure "50" stonds
opposite the little block dot on the inside of the diol.  This                                                Iwill produce o shutter speed of 1/5oth second.  ln o
                       moy                         speed                               be selected.       monner,             ony othersimilor                                         exposure speeds       I                           provided                                   with  The Model                      ore                   I comeros
of 1/25, l/50, 1/15, l/100, 1/2OO ond I /500th second
os well os bulb..
  The slowest speed on Model I is 1/25th and the fostesr
is l/50Oth second. B stands for bulb, this speed depends
on how long lever (10) Fig. I  is depressed, the shutter  is
releosed when lever is releosed.
    It should be noted thot the shutter speeds moy be altered
or set either before or ofter the shutter hos been wound (by
the film tronsport ond shutter setting disc (Zl FiS. I.
   After eoch exposure, it is necessory only to moke one ond
o froction turn of disc (21 Fig. I by meons of the foldrng
lever  ( I ) FiS.  I .  This oction performs two duties auto-
moticolly.   First, it rewinds the shutter for the next
exposure ond second, it moves the film the exoct distonce
so thot the next film oreo to be exposed is perfectly
odjusted over the picture operture. Thus, it becomes pos-
sible to moke o series of exposures with the Korelle Reflex
with surprising ropidity.
    HOW THE EXPOSURE IS MADE
    It is interesting to know just whot hoppens when theshutter releose button (10) Fig. I  is pressed (or the coble
releose is used in (9) Fig. l.  The first oction is the move-
ment of the reflecting mirror in on upword direction. This
cleors the field ond permits the light roys to poss olong to
the reor of the comero where the film is locoted. As the
mirror moves upword ond out of the woy, the focol plone
shutter is outomoticolly releosed, thus cousing it to poss by
 its slit or operture permitting the light to moke its im-
pression upon the film for o fleeting froction of o second,
                        www.butkus.us

Poge Thirteen
     HOW THE EXPOSURE lS MADE (Cont.)
      As the shutter releose button is releosed (or permitted to
      come bock to its normol position ofter the exposure), the
       mirror outomoticolly drops bock into position for further
        focusing purposes.
       When it is considered that a highly precise ond well-mode
I      mechonism only is copbble of performing all these duties
       olmost simultaneously, the morvels of modern photogrophic
I       design ond engineering con be appreciated.
       THE DIRECT VISION VIEW FINDER
         While the ground glass focusing device will probobly be
       used for the vost mojority of pictures, there will orrise
        occosions when the camero will be wanted to be used at
        eye-level insteod of woist-level. Porticularly ot the roces,
        sport meets ond similar rapidly moving events ond subiects,
      a quick glonce will be oll thot is permitted, owing to the
        speed of the object being photographed.  In such coses, the
        focusing hood is folded down ond the metol, direct-vision
         finders (8-8) Fig. I erected. By looking through the squore
        apertures (small reor ond lorge front), the field of view, os
        covered by the lens, can be cleorly seen. This finder per-
        mits rapid work, olthough it does not give ony indicotions
       of the focus of the lens. This meons thot the lens must
       be pre-set for the given distonce ot which the subiect to be
        photographed exists. This is a simple motter, and becouse
        of the inherent depth of field of the lens, consideroble loti-
        tude in focus is Permitted.
1           CHANGING THE LENSES
                lf you wish to exchonge the lens at present- in Ll5s forI       ohother one, screw out the one lens from the lens mQunt
       ond screw in the other.  In chonging the lenses moke sure
         that the dots on the mount and on the lost ring of the lens,
       come to rest exoctly together.  lf this is not precisely ad-
        hered to in the chonging of the stondord lenses then the
         releose will be foulty owing to the impoired movement of
        the mirror.

           GENERAL HINTS
  The previous instructions,on the use of the Korelle Reflex
have been made deliberately simple ond brief, becouse the
comero is simplicity itself, ond no one will experience the
 least difficulty in operoting  it providing the few instructions
given ore followed and the following hints observed. The
following suggestions, if corried out systemoticolly, will result
in perfect pictures ot oll times ond under oll conditions
with the Korelle Reflex.                      Bu*K-g,orj
     l.   Never force the mechonism of the Korelle Reflex.
Force should never be required, ond when it is, it is a clear
indicotion thot something is wrong.  Stop immediotely!
Determine the couse for the need of forcing ond rectify  it
before proceeding. Remember, the Korelle Reflex is a pre-
cision instrument and will operote smoothly ond perfectly
if handled properly.
  2.  Keep the lens and filters cleon ot oll times. pon't__
use chemicols (such os olcohol or xylol) for cleaning. lf
moisture is necessory, simply breathe upon the glass surfoce                      .),,tond wipe gently. The best cleoning medium for this pqr-
pose is lens cleaning tissue.
  3.  Keep the camero cleon ot oll times.  Wipe dust,
dirt and sand off the exterior periodicolly by meons of o
piece of soft fabric. Dust the interior of the comero, por-
ticulorly the film spool chambers ond the film rollers ond
trocks, with a soft camel's hoir brush. When in desert ond
sondy beach regions, be extro coreful about this, for often
microscopicolly tiny porticles of sond may become lodged in
the camero and couse untold injury through scrotching the
film as it posses through the camero.
  4.  Alwoys keep the comero in o case when not in use.
This protects  it from dust ond sudden jounces, especially
when troveling. The "ever-ready" cose which can be fur-
nished for the Korelle Reflex mokes on ideol ond convenient
cose for the camero. lt is most important to keep the film
trock and rollers free from dust, os otherwise the film moy
be scrotched. A small brush will be found useful for re-
moving the dust.

deliberotely with a squeezing motion. lmitote the expert              I
morksmon who, ofter toking coreful aim, does not jerk thetrigger of his rifle, but rather "squeezes" it.  This "trigger   +Isqueeze", as it is called, does not destroy the oim      with
either a rif le or comera. You con use comporotively slower
shutter speeds with the comero hond-held thon otherwise,
if you observe this little hint.

The result will give the f: volue or lens diaphrogm stop to

ond dull, lifeless results, use a Rexo lens shode over the lens
every time you moke on exposure. This is particulorly true
when photogrophing ot the seashore, on sondy beoches, on
the water or when there is snow upon the ground. These
reflect o tremendous omount of light into the lens and often
produce o thin veil of fog over the entire negotive oreo,
thus cousing a loss of brillionce ond snop.
     I l.  Choose your films wisely for the Korelle Reflex.
Both the "chrome" type of orthochromotic films ond the
fine groin ond super speed ponchromotic films may be used
with good success. Films of the former type include Agfa
Plenochrome ond Eastmon Verichrome. For fine groin pan-
chromotic film, choose Agfo Finopon or Fine Groin Plena-

   12.  Unless speedy films ore necessary,  it is odvisoble to
use one of the fine groined films, for this procedure permits
greater enlorgements to be mode without resorting to speciol

of the principol imoge, the composition ond the orea covered
by the lens. Be sure oll is exoctly the way you wish it to be

  11. To obtain the moximum results from Korelle Reflex
pictures, the owner is urged to do his own developing and
printing. These motters ore not ot all difficult in these
doys, os some beginners seem to believe. On the contrary,
they ore eosily accomplished anywhere; a city oportment, o
steamship, hotel room or ony other ploce where film de-
veloping is hordly thought of os being possible.

modern developing tanks now ovoiloble. These moy be

mended for its remorkoble simplicity ond low cost.
  19.   lt is not even necessory to mix chemicols; excellent

to being wonderful developers, possess unusual fine groin
choroctJristics. One of these prepored developers (either
liquid or powder) should be used, especiolly by the beginner

  2Q.  lt is necessory, for best results, to hove all solutions
used ot the same tennperature. Generally this is 65'F.
Voriotions between solutions will likely couse whot is known
as reticulotion, ond ohce this happens, the film will be
ruined.
  21.  In hot weather, a speciol hordening solution should
be introduced in the routine of film development. Such o
solution (of which there ore severol brands ovoilable in
prepored form) couses the delicate emulsion to toughen and
become resistont to scrotches, pin-holes, etc.

    - For taking pictures  at night-outdoors   or indoors-or   in highspeed shutter  work  in  action  photography,  a genuine Kalart
Flash Synchronizer, designed especially for the Korelle Reflex, is
now available.  Newspaper men and sports photographers  will
find a flash synchronizer  indispensable.......The flash synchronizer
consists of a  reflector and socket  for a photoflash  bulb.       It
contains a mechanism that couples to the shutter  of the camera.
When properly  adjusted   it  synchronizes the  flash  of  the bulb
with  the action  of the  shutter.       It  enables you  to  take high
speed snapshots of moving objects at night  or in  dimly   lit  rn-
interiors.   Flash bulbs particularly  well suited  for  synchronized
use with  the  Korelle  are Superflash Nos.   I and 2 or  General
Electric No. 7.  Their use is recommended.

           COLOR FILTERS
    If  you would produce the  finest  negatives  with  the  Korelle
Reflex by  all means add a set of  filters  to your accessory  kit.
While  wonderful  improvements have taken place  in  the  color
sensitivity  of both  ortho  and panchromatic  emulsions, certain
colt.rrs are more sensitive  than  others.   The judicious  use of
filters  corrects this-and  when the subject matter  at hand calls
for emphasis on any one color a color  filter  with the correct  film
will  give you what you want.  When working  with  orthachro-
matiC films such as Verichrome or Plenachrome, which are overly
sensitive to  ultra  violet and blue the use of a yellow  filter   is
recommended on all outdoor subjects which include a portion  of
sky area.  The yellow  filter  holds back the blue permitting   it  to
register with a distinct  tone value in the print.      lf clou4s a-re in
the sky they will stand out in contrast  to the blue of the sky-
and clouds often make an otherwise ordinary  picture  beautiful.
  When working  with panchromatic  film  in the camera the use
of a green filter  is recommended.   Panchromatic  films,  while
sensitive to  all  colors are overly  sensitive to red as well as to
the blue and a green filter  corrects  this, permitting  each color to
register  in  its  correct monochromatic  value on the  film.  The
usL of orange or red color  filters  will  provide dramatic  effects.

        COLOR FILTERS (Cont.)
The deeper the red color  of the  6lter  the more of the blue  it
cuts  off.  Skies can be brought up as almost  black,  in sharp
contrast  to  the white  of the clouds.   When shooting  distant
landscapes a red  filter  cuts through the distant haze, brings up
distant objects sharp and clear.
    It should be remembered  that  filters  cut  off a certain amount
of light-and    to compensate for  this  loss of  light a longer  ex-
posure should be given.   Standard  "ldeal"   filters  are recom-
mended for use with the Korelle. These filters are so constructed
that  they nest one over  the'other,  permitting  the use of more
than one 6lter  at one time.  Rexo sunshades may also be used
with the Ideal  filter.
                         8U4K.S ',TS            LENS SUNSHADE
  A sunshade placed on the lens  will  accomplish wonders  in
producing  brilliant  snappy negatives.  Rays of Iight  striking  the
convex surface  of  the lens are  reflected  into  the camera and
reflect from the bellows to the film  resulting  in a slight haze or
fogging  effect.  A sunshade effectively  cuts  off these rays and
assures negativ'es of sparkling  brilliancy'
        LENS EXTENSION TUBES
  For  macragraphy  or  the  photographing   of  small  objects
larger than actual  size, lens extension tubes are available'  By
extending the distance of the lens from  the  film,  magnification
of the irnage is secured-the  X  factor  being controlled by the
length of the extension.  Small objects so photoggpled  may be
sub-sequently enlarged in  printing.   Thus a-new- fi9ld-is  op-ened
to the enteiprising  amateur who owns a Korelle  Reflex.  Lens
extension tubes are availabie  in four standard sizes as listed  in
the table below.  The table shows you the necesbary distance
of the carnera to the subject  for securing sharp focus  as well
as the picture area covered.  In use the lens is rernoved from
the carriera-the   extension tube threaded into  the lens opening
and the lens  is  then mounted on the  protruding  end of  the
extension tube.
