TTIE WRATTEX

  The Wrayflex is a single-lenseye-levelreflex camera u_sing
  35 mm. film. lt takes interchangeablelenses,and has a focal
  plane shutter. The complete camerawith its 2 in. (5 cm.)
  f2'  fensmeasures5* x  3t x 2* in. and weighs74 oz.
   The camerabody is die'-cast,ind hasa retiovable back with
  anodized pressure plate.  lt  accepts standard 35 mm.
  cartrldges is well as reloadableself-openllg metal cassettes.
   A sel-f-cappingfocal plane shutter ls built into the camera
  body and travelsfrom rlght to left. Self-cappingmeansthat it
  remhinsclosedwhile being wound up, "focal plane" means
    it movesright In front of the negatlvematerlalfor maximum
  efficiencyat the same time ensurlng full light protectio.n.
  The Wr-ayflexfocal plane shutter has settings of  l/2,  llr,
     f /10, 1125,l/50, l/100, 11750,l/500, and l/1000 second,
  as well as B for tlme exposures.The speedsare set on a
  single shutter speed dial on top of the camera. Flash_syn-
  chrbnization for both electronlc flash and flash bulbs is
   built in.
    The Wrayflex  is produced in two  picture sizes. The
  conventionai24 x  36 mm. size similar to Leica, Contax,
  Kine Exakta,etc. for 36 exposureson a full length film has
  been introduced recently to  cater for  "conservatiYe"
  demand.
    The original Wrayflex size is 24 x 32 mm. for 4?exPosures-
  on a full-length 35 mm. film. Thls origlnal departure .of
  traditional standardsoffers a3:4 ratio of the shorter to the
  longer side of the negative,this is quite generallyaccepted
  as pleasingto the eye and more widely used than the Z:3
   proportion of the 74 x 36 mm. size. lt alsooffers an economy
   in materialand In particularlyin colour film which is four or
   five tirnes the price of blaik-and-white, by produclng 24
  frames insteadof only 20 frames.
    The reflex focusingfinder of the Wrayflex is used at eyg
   level. The actual taking lens serves both for focusing and
   taking the picture. A movable mlrror  reflects the picture
{  to be taken on to a ground-gfassfocusingscreen.

In a twin-lens reflex camera, or for           THE NEFLEX
that  matter   an), camera  with
separate  viewing  and   plcture-
taking lenses, tho  lenses do not
see the same view. This parallax is
more critical the nearer the sub-
lect to the camera. lt limits the use
of  twin-lens   reflex  carneras  in
accurate close-up work.
   s     The single lens reflex camera ls
                                                 free from  that weakness, but  In
                                       exchange has to put up with the
                                                loss of a split second between the
                                      moment, of viewing and taking the
                                                picture. At  the moment  of ex-
                                          posure, focusing and viewlng are
                                              not possible.
                                      The reflex focusing $rstem of the
                                           Wrayflex  is used at eye level. The
                                               actual taking lens serves both for
                                           focusing and taking the  picture
                                      and is used to form the image on
                                              the film as well as to  reflect the
                                                picture to be taken on the ground
                                             glass screen.
                                      By setting the shutter, the mirror
                                                            is introduced into the path of the
                                                        light rays between lens and film.
                                      The image ls double reflected by
                                          two  mirrors and viewed by the
                                        eye throu8h  the eyepiece.
                                  On releasing the shutter (bottom)
                                              the reflex mirror  cradle is swung
                                       up out ofthe path ofthe light, and
                                              the  picture disappears from  the

Film and focusingscreenare for all Intents and purposes
at the samedistancefrom the lens but in differentposltions:
at right angleswith eachother. The film runs alongthe back
of the camerawhile the focusingscreenis on the top of it.
Thusthe light enteringthrough the lenshasto go alternately
in two directions:once to the focusingscreenand once to
the film. This two-way traffic is controlled by a mirror on
point-duty.By settingthe shutter, the mirror is introduced
into the path of the light-raysbetween the lens and film,
thus reflecting the image on to the focusing screen, This
then shows exactly the sameoutlines,definition,depth of
field and (in the centre of the screen)the relative brlghtness
of the subJectas will appearon the negative.
  When the camerais held horizontally,the image appears
the  right way up but reversed left-to-right. With  the
camera held upright the image is seen upside down but
correcr left-to-right.
  With the standard2 in. (5 cm.) lens in the camerathe
finder imageappearsabout two-thirds life size.The central
focusing magnifier on the screen enlargesthis section by
another 50 per cent for critical focusing.The field seen is
fully accurate,without any parallaxerror.
  On releasingthe shutter for the exposure the cradle
holdingthe mirror and ground glassscreenswingsupwards,
coveringthe viewingaperture.The camerais now light-tight
and the path of the light to the film is clear.
  The folding film transport key is located in the centre of
the baseplate of the camera.Half a turn on this key re-sets
the camera for the next exposure. lt thus combines the
actionsof transporting the film by a full frame, setting the
shutter, repositioning the  mirror  cradle for  viewing,
and advancingthe exposurecounter.
  The camera top plate carries the body releasewith an
outside thread which acceptsa screw-over cable release.
The film counter and rewind knob are alsofitted on top.
  The  interlocking mechanism automatically prevents
double exposuresor blank frames,

The lensesof the Wrayflex are interchangeable.In addition
to the standard2 in. (5 cm.) lens,a wide-anglelensof l$ in.
(3.5cm.) and a long focuslensof 3f In. (9 cm.) are avallable.
As the lens itself is usedto producethe reflex finder image,
the correct field with any lens is automaticallyshown in the
finder, and no separatevlewfindersare required.


The  Wrayflex   Lrenses
  The Wrayflex is fitted with  either the 2  in. (5 cm.)
Unifite f2or Unilux f2.8 asstandardlens.
 THE 2 in. (5 cm.) UNILITEF 2 is a five-componentanastigmat,of
exceptionally high resolution, even light distribution and good colour
correction.  lt reaches its optimum on marginal resolution at  f  ll.   lt  is
built into a helical focusing mount with a focusing range from 3 ft. to
infinity. The aperture scale closes down to  f 22 and is fitted with  click
stops. The Unilite  is a universal lens suitable for  all types of general
photography. On account of its fast aperture  it  is suitable for pictures
in poor  light conditions, indoors, and fast moving subjects. lts good
colour correction makes it particularly suited for colour work.
  THE 2 in. (5 cm.) UNILUX   f 2.8 has four elements and similar per-
formance as the  f 2 lens (above) but  at full aperture transmits only
half the amount of light as the f 2lens, somewhat limiting its appllcation
under extreme conditions.
  THE l8 in. (3.5 cm.) WIDE ANGLE LUSTRAR f 3.5 is a four-com-
ponent anastigmat of  flat field, high resolution and very reasonable
covering power.  lt covers a field of approximately 64" (dlagonally) as
compared with 46" of the standard 2 in. (5 cm.) lens.  lt will be found
particularly useful for taking interlors, where as wide a field as posslble
has to be included, and also for taking large groups, for photographing
In narrow  streets-in   fact wherever  the subject-camera distance is
restricted. A modest exaggeration of perspective of the wlde angle lens
can be put to good use in special cases-for example to enhance the
foreground of a composition or  to  introduce some other  deliberate
distortion. On the other hand its focal length is not so short as to
produce unpleasant distortions and  it may also be found useful as a
general purpose snapshot lens. On account of the great depth of field,
this lens can be employed with  pre-set zone focus setting for quick
actlon snapshots.lt ls built into a helicalfocusing mount with a focusing
range from 3 ft. to infinity. The aperture scale closes down to  f 22 and is
fitted with click stops. One has to put up with the fact that the illumina-
tion towards the edges of negatives taken with  a wide angle lens is
bound to fall off to a slight degree. This can to some extent be offset by
giving a Senerous exposure.

THE 3* In. (9 cm.) TELEPHOTO LUSTRAR f4  is a four-comPonent
anastigmat of high resolution, flat field, and very good covering power
and colour correctlon.   lt covers a field of 27" (diagonally), giving a
linear magnificationof 1.8 times, or over 3.5 times in area compared
with the standard 2 In. (5 cm.) lens. In other words  it gives a larger
reproduction  of the subject.  lt  is particularly useful for long-distance
work, such as photographing mountains or inaccessiblearchitectural
detaiis, or when  taking animals, sports photographs and  portraits.
There  the  mellowed  perspective which can be obtained with  the
3{ in. (9 cm.) Lustrar from an increased working distance is pictorially
advantageous.
  This lens is built into a helical focusing mount with a focusing railge
from 7 ft. to infinity. The aperture scale closes down to  f 32 and is fitted
wlth click stops.
   All  lenses have an  internal  thread  to  accept  filters  (see p.  64),
supplementary lenses (see p. 68), and lens hood (see p. 56).
  Both 5 cm. lensesare suitable for use in an enlarger.
  When usingfast lensesit is wrong to assumethat the high
correction of the Unilite lensesenablesone to use them
invariablyat their full opening.The depth of field (seep. 53)
of these large aperture lensescan only be comparatively
small at their original aperture, so that, more often than
not stopping down becomesnecessary/.Large aPertures are,
however, a very welcome reserve for adverse lighting
conditions and, in any case,they ensure a bright focusing
image on the reflex screen.
  When using the 9 cm. Lustrar, focuslngwith the longer
focal length has to be more accurate,as again,the depth of
field is considerablymore limited than wlth the lensesof
shorter focal length. At the sametime, owing to the longer
axls, slow speedsof l/50 and l/25 secondswith this lens
tend more easilyto camerashakelf the camerals not held
very rigidly or usedfrom a tripod.
  The treatment and care of the lenses is a matter of
importance.On accountof its chemicalcomposition,optlcal
glass of high quality is susceptibleto the influencesof
moisture, and for this reason touching the glasswith the
fingersshould be avoided.When not in use the lens should
be protected by the lenscover. Sincecomplete protection ls
impossible,the lens surfaceshould be cleanedoccasionally
wlth a clean,soft chamoisleather.

Lrens Coating
       All Wrayflex lensesare coated.This processconsistsof the
    application of a microscopicallyfine deposit of some in-
    organic substanceon the glass surfaces, it considerably
   reducesthe light reflectionat glassto air surfacesin the lens.
   The gain will be fully appreciatedif it is understoodthat for
   examplein a four-componentF3.5lensthe lossof light due to
    surfacereflection is in the region of 30 per cent, which can
   be reduced by coating to about 5 per cent. Apart from the
    gain in speed of the lens whlch may be in actual practlce
   50 per cent (half a stop) it is of rather greater importance
    that the scatter of light which impairs the contrast of the
   imagels eliminated,giving a more brilliant negative,especi-
    ally in the regionswhere the tones are most subduedand
   where consequentlybrillianceand contrastare most needed.
   The fact that a lens is coated can be recognizedby observing
   a reflection in the lens of, let us say a lamp. lt appears
    distinctlycoloured,as a rule rather deep blue with a tinge of
    red.


   Changing   Lrenses
     Changing lenses In the Wrayflex is simply a matter of
   unscrewingthe lens by holdingand turning its back milled
    ring. This can be done before or after the camera shutter
   has-been set. As already mentioned, the screen of the
    finder shows the correct view, free of parallax,whatever
   lens is employed.

HATVDTINGTHE WRAYFI,EX
       Iroading
       To start with we take it for grantedthat we haveour
      Wrayflextogetherwith a loadedstandardfilm cassettein
        front of us (seep. 27 for the universalcassette).Our first
       taskis to loadthe camerawith film.Thisshouldbe donein
      subdueddaylight.
                  l.  Remove camera back.
           2.  Pull out rewind key.
           3.  Insert film and push rewind key back.trut           4,  Fix film end on take-up spool.
           5.  Transport once.
           6.  Close camera back.
           7.  Transport fllm twice and release.&           8.  Set film counter to No. 0.
                    l. The camera back can be removed after pushing up thc catches on
              either side.
            2. The rewind key-marked  "rewind"-on    the top plate is pulled out
            as far as it  will go.
            3. Place the  film  in cartridge  into  the empty chamber below the
            rewind  key, purh back the rewind key which  wlll now hold the
              cartridse  in oosition.
           4. Pull ou-t 4-5'in.  of film including the shaped lead. The cream-
             coloured emulsion side has to face the camera front. Bend the first
                         f  in. of film back and fix  it under the clip of the take-up spindle,
            which is housed in the chamber opposite to that of the film cassetto.
          Make sure that the film perforation engages in the sprocket wheel
w          theand cassette.the film is taut across the gate; any "slack"  is pushed back into
            5. Make sure that the rewind lock on the bottom of the camera is set to
               "L".  Give the winding key half a turn  in a clockwise direction to
          make sure that the film progresses smoothly across the gate and
              that the sprocket engagesthe film perforation correctly, Press the
              shutter release.
            6. Replace the camera back and lock  it by pushing downwards the lock
            catches on either side.
            7. Transport the film two frames by twice turning the film key and
              releaslng. This action moves on the first part of the film which has
           been exposed to light on insertion. When winding on, the rewind
            key on the top plate must revolve in an anti-clockwise direction.
             This proves that the film is being pulled out of the cassette properly.
                       lf ashort e.9.20 exposure colourfilm  is used it is a{visable to takq 11

   Carrying  the Wrayllex
     However eletant it may be to carry the cameraon a long
   strap from the shoulder,this positionis qulte unsuitablefoF
   quick actlon.                    a good shot has been-lostin this way. A                Y.n)r
    better method ls to carry rhe Wrayflex in its ever-r6ady
   caseon a short strap round the neck, so that it lies on oners
    chest-in. the rlght position ready for rvork. Openlng the
   caseand liftlng it up to the eye is then a mattei of Jspllt
   second.
     The ever-ready case carries the Wrayflex ready for use,
   and there is a retaining screw which prevents the camera
   from falling out of the-opened case.

    Manipulating    the  Wrayflex
       Generally it  is of foremost importance to  acgulre     _
    sufficientexperiencein manipulatingali partsthat eventirally
   lead to takint the- picture. So get thoroughly acqualnted
   wlth the ways in which to work the cameracontrols before
    actuallysetting out to make photographs.Surely one should

   wasteful of lives-but   it is not lessvriastefulof live'pictures,
      if not of the camera itself.
    The following are the mechanicalpoints that must be
    particularly watched when using the Wrayflex:

Viewing  vyith the Wrayf,ex
     The eye-levelreflex finder showsthe imageformed on the
   ground glassscreen by the light which enlers the camera
    through the lens and is reflected by a mirror. The reflex
   imageis only visibleafter the film hai beenwound on, and it
    disappearsonce the shutter is released.lt has a twofold
    purpose: to show the field of view, and to permit accurate
    focusing.
     There should be no difticulty in determinins the field of
    view. View the plcture first with the apertureTuilyopen to
   ensure the brlg.htest.possiblereflex ihrage.Althbugh you
   may automatlcallyhold the camera quite level, malie sure
    that the vertical lines of the plcture run parailel wirh the
    sidesof the g.roundglassfram6, except whLn you aim at an
    intentionaltilt.
        secondpurposeof the reflex finder, obtainingthe best        . ff,t

    factors ensuringgood results.The less experienced'userof

   sharpimpressionof the imageas best definitibn.
     There are, however, different degreesof sharpnesseven
    at full aperture.The best way to arr-iveat criticai definltion
     is to turn the helicalfocusingmount of the cameralens to
   and fro while observinghow the main obJecton which you
    intend to focus becomes more and mol.e sharp up tb a
    certain.point,beyondwhich it will againlosedefinitidn.tt is
    at this "beyond" stage that you hav-eto reverse the move-

      It is a caseof "bracketing" from the shari surroundingto

                                                          legs well apart.



For horizontal photographs (top left) hold the camera in the ball of your right hand
with right index finger on the ihutter  releaseand thumb on cameia back.-The left
handmanipulatesthe film key and focusing mount and finally supports the camera
when releasing.For vertical shots (centre)-thecamera is heli agiihst the forehead,
supported by tlu   riglt  hand from  underneath, with  the  rigfrt thumb on the
releasebutton. The left hand acts as aboye.
Whenever possible support your body against something sotid such as a tree, or

       In its upright poslrion the Wrayflex picture is seen slde
    correct and in consequencefollowlng a lubject one hasthe
    natural movement,but the imageis upsidedown.


    Holding   the  Wrayflex
          It is obvious that the camerashould be held as steady'theas
    possible,as the slightest shake, even if not seen In
    original negative,will becomevisible in the enlargement.
   Always stand with your legs apart.
      A.particularlysteadyhold of the camerals necessarywhen
   working with the long-focuslens (see p. 8). ln this cise the
    centre of gravity is further forward and  it  is therefore
    desirableto hold the cameraby graspingthe helicalfocusing
   mount wlth the left hand, while the right hand steadiei
    the cameraand operatesthe shutter relelse.
        '     As the Wrayflex ls horizontally built, it obviously-inlends
     Itself most simply and naturally for photographs   this
    position. Hold  it  in the right hand wtth the right index
    flngqr-ol th9 shutter release,thumb on camerabick, using
    the left hand to manipulatethe film transport key, actuate

     For upright shot, hold the camera againstthe forehead.    _
   Support it with the right hand from underneath,witt the
    rlght thumb on the releaseknob. The left hand mar.,pulates
    the film transport, the focusingmount and finally supports
   the camerawhen releasing.
     To releasethe shutter (seep. l8) pressthe shutter-release

     3, Focusand determinethe pictureareaas describedon p. 14.
     4. Adjust the iris diaphragmby turning stop-ring (the milled ring on
       the front of the lens mount) until the stop required is opposite
       the index mark.
       The lens is fitted with click-stops,you can therefore distinctly
        feel the iris ring click into position at each stop. This facilitates
       setting the aperture by feel without looklng when the camerais
       held at eye level. After havingfocusingwith full aperture-let us
      saywith the f2 lensyou only haveto turn the iris ring to the thlrd
         "click"   if for example stop f5.6 is required. After some practice
       an)raperture canrhus be selectedin an instantand without remoyinS
       the eye from the camera.
       The purposeof the iris diaphragmis to adjustthe effectiveopen-
       ing of the lens. The smaller this opening (i.e. when the lens is
       stopped down) the greater the depth of fleld. At the sirmetime, as
       lesslight can piursthrough the_lensin any giventime, the exposure
       time must be longer (see p. 54).
     5. To releasethe shutter gently pressthe releasebutton. To do this,
      use the first joint of index finger of your right hand to pressthe
       button. At the sametime the thumb should be placedagainstthe
      back of the camerairs support. Speedsfrom l/25 to l/1000second
       are instantaneousand can be taken from the hand. lt is advisable
        to usethe slower range, l/25 and even l/50 second,as sparinglyas
       posslble,as there is somedangerof jerking the camera,and even a
         ilight ierk, six or eight diametersenlarged,resultsin unsatisfactory
        definitlon. On the other hand, if you have a steady hand and a
      chanceof leaningagainsta wall, etc., or-eyen  better--+upporting
       the cameraonsomethingsolld,not onlythe l/25 but l/10 and l/5
      secondexposurecan, with care, often be releasedwithout shaklng.
        Time exposuresshould be made with the cable release,which
       screws over the release button. After having taken all pictures
        (the numberof exposurestaken is automaticallycountedon the film
       counter) the film has to be rewound into its cassettein order to
        remove'it from the cameraand replaceit by a new film. Both these
       operationsshould be done in subdueddaylight (see p. 20). lf the
        film key cannotbe movedthe completehalf turn, this is an indica-
        tion that you have come to the end of the film. The film counter
          will also have stopped somewhere in between two figures and
        therefore no longei showsthe correct number of exposuresmade.
      Do not try to force the film key, you would only tear the film end
       from the cassettecentre spool,which meansyou haveto removethe
         film In the darkroom. lf you feel a -r,eslstance,stop windlng on and18    rewind the film as describedon p. 20.

        rewind the whole film intb the cassette, when the film would have
          to be extricated  in the darkroom  in order to reload  it later on.
      3. Remove the rewound film from the camera. On the beginnlng of
        the film note for reference the numberofexposures taken and then
        put  it into a container or wraP  it up. Now you can load the camera
        with another type of film.
      4. To use the partly exposed film again, it has to be loaded into the
       camera in tlie usiral way (see p.  I l).
      5. As many exposures as have already been taken on the film must now
       be exo6sed'with the lens cap on the lens. To be on the safe side it is
        advisdble to altow one or t*o  frames more. When making "blind"
       exDosures it  is wise-in   addition  to covering the lens-to  stoP  lt
          fuliy down and to set the shutter to the highest speed.

   Cutting  Off Exposed Lengths
        tf a film whichis only partlyexPosedhasto be processed,
      it canbe cut off in the dark room or in comPletedarkness.
           l.  Wind on film and oPen camera.
       2. Cut film.
       3. Remove film from take-uP sPool.
       4.  Reload remaining Portion.
         l. After the last exposurewind the film transpolt once mcre, then in
       the dark open the cameraback.
      2. Cut the film about I  in. awayfrom the cartridge.
      3. Removethe exposed part on the take-up sp99l by pushingthe
       reversinglever in the 6ottom of the cameiato R, winding the film
         off the t-ake-upspool and wrapplng it up in three layersof black
      oPaquePaPer.
      4. The remaining film in the cartridge can now be re-inserted, the
        reversing levJr is set back into L position and the cameraclosed.
