Praktica Cameras PR (35mm) User manual

The 35 mm SLR camera is recognized
     the world over by discerning
    amateurs and professíonals alike as
    the best camera on the market.  lt is
     su perior to every other camera be-
    cause of its idealvieurfinder, simple
    lens-changing technique and vast
    range of attachable accessories. The
      first ever 35 mm SLR camera was
    created by design engineers in
    Dresden over 50years ago. Ever
     since then  it has been continuously                                                                          l.ilí,$    developed              and improved.

Faster, higher, longer-these are some of the criteria
used in short. The chase after records, either personal
bests or in the different classes, is the motivation. And it
is speed and pacethat impress. Allthe sweat of training,
the sacrifices and the set-backs are forgotten when
success finally comes. The committed sport photo-
grapher owes the sportsmen and women a similar
degree of quality. Speed, sureness and quick reactions
are also attributes of the PRAKTICA camera range. This
teamed with an experienced photographer behind the
camera providesthe basisfortaking top-class photos of
top-cl ass spo rti ng ach  i eve m e nts.

Automatic shutter speed control is
    an impressivefeature of the PRAKTI-
   CA BCA. You selectthe aperture and
    the camera computer automatica    I ly
     sets the correct sh utter speed, which
    can be anywhere in the range from
     %ooo s to 1 s. The electronics selectthe
    values steplessly. That means that
    speeds like %rs s or %6 s are possible.
   And that is exactly what you need for
    correct exposure whatever the situa-
    tion. Now every photo can be a suc-
    cess. And because we've made the
    technical side of the PRAKTIcA BCA
    uncomplicated you can devote your
     full attention to you r subject. With
     this handy automatic SLR camera,
   you can use your photographic
    imagination to the full.

Flash is always used wheneverthe
     light is not bright enough for photo-
     g raphy. That's why PRAKTICA
   cameras are fitted with a hot shoe
    that accepts an electronicflash unit
    with a counterpart. These two parts
    guarantee sure mechanical and elec-
    tronic co-ordination between ca mera
    and flash unit. With computerized
    flash units we can forget about the
    long and involved calculations that
    had to be done for each photo in the
     past, forthe guide number of the
    flash unit, the distance of the subject
    and the aperture, for example. A
    computerized  unit will automatically
    provide the necessary light dosage
     for each picture, according to the
    distance ofthe subject from the flash
    and the amount of light it reflects into
    the camera. And  if you use a com-
    puterized flash unit specially de-
    signed forthe PRAKTIGA BC 1 or BCA
    the camera will automatically select
    the flash sync time. As soon asthe
    flash is ready a green LED lights up in
PHAKTIGAthe viewfinder next to the flash sym-
 lncreasing the pleasure

The automatic exposure system of
    the PRAKTICA B cameras meansyou
    no longer havetoworryworking out
    the shutter speed. Once you've
    selected an apertu re appropriate to
    the general lighting conditions  all
    you've got to do is press the release
    button. Correct exposure  is guaran-
    teed,  f rame by  f rame. The camera
    computer takes every change in the
     lighting conditions into account. The
     light which will produce the picture is
    metered insíde the camera. The in-
     tensity of the light striking the highly-
    sensitive light receiver-  it depends
    on the brig htness ofthe su bject to be
    photographed - determines the re-
     sult of the measurement. The light is
    measured atfull aperture and max-
   imum viewfinder brightness, and the
     val ue is electronically transferred
     into the computer.
     ln PRAKTICA cameras. the centre-
    weighting light metering method is
    applied. The light is measured in the
    centre of theviewfinder.  ln almost

The viewfinder of the PRAKTICA
   gives you a large, clear and bright
  image with true colour reproduction
   for you to judge the picture and focus
   accurately. That's the principle be-
   hind SLR cameras that never fails to
   impress. The light passesthrough
   the lensto reach the mirror. From
   there  it is reflected through thefocus-
   ing system to the prism and on to the
   viewfinder eyepiece. A Fresnel lens
   forms the focusi n g system. The
   image-receiving surface of this lens
    is precision engineered so that this
   lens alone would guarantee accurate
   focu si ng.
   But in order to achieve the
   highest possible degree ofsharP-
   ness in focusing, additional indi-
   cators are positioned in its centre.
  And this is where the functioning of
   the triple wedge is so imPressive
   enabling you to focus with pin-point
   accuracy.
   The wedge system clearly
   indicates even the slightest degree of
    blur by staggering the contours oÍ                Fï

35 mm SLR cameras are associated
         with advanced tech nology, versatili-
             ty, sureness and reliability, Some-
        timesthe SLR camera is described as
          a camera that can almost perform
          miracles. Ouite rightlytoo. And in the
        50yearsorso sincethe birth of the
       SLR 24 x 36, PRAKTICAcameras
        have done a great deal to contribute
          to their popularity. The routeto suc-
         cess of the PRAKTICA L model has
        been particularly sensational.
       And even though in almost a decade
          millions of these cameras have been
        bought all overthe world the extra-
         ordinary demand remains the same
         as it ever was.
        The latest model in this popular
          series is the PRAKTICA MTL 5 B. lt is
         the ideal camera for an uncompli-
         cated introduction into SLR photo-
         graphy, having all the usual features
           of the SLR camera, like the viewfin-
        der,TTL light measurement, inter-
        changeable lenses and a multitude
           of accessories. And just like its pre-

Trees, whether standing alone or in groups, are almost
everywhere around us, givíng the scenery  its particular
character. They also ref lectthe seasons. The multitude
of form and colour gives off unmrstakeable optical
signals, which is probably the reason why they have
been favourite subjects for pai nti ngs for centu ries. And
the same appliesto photography. Trees ntake satisfying
subjectsfor photossincethey place almost no lÍmit on
yourcreativity. According to the idea and mood of the
photographerthey can form pictures that are sober and
business-like or romantic and poetic. Their delicate
graphic lines and large flat areas make appealing photo-
graphic subjects. Trees offer countless possibilites,
whether you want a light, f loating mood or to create an
impression of heaviness. And effective use of colour
can make the picture even more interesting, especially
blue colours wltich seem to recede into the distance.

The large, bright image of the Fresnel
    lens with its threeway focusing sys-
   tem togetherwith the internal light
   metering of the PRAKTICA MTL 5 B
    provide a sound basis for simple and
    effective photog raphy. The internal
   metering system forms part of the
   automatic shutter speed control
   mechanism. You choose the aper-
    ture or shutter speed and the rest ls

The automatic shutter speed control
  system of the PRAKTICA BC 1 and the
  BCA can be manually overriden. This
    is usually only necessa ry for photos
  taken under extreme lighting condi-
   tions, such as against-the-light shots
  and where dark and light portions are
   not balanced. with the PRAKTICA BC
    1 you justtake a light measurement
    of the most important detailfrom
   close-up and storethevalue  in the
   camera's memorY. But such a close-
   up measurement  is not always Pos-
   sible: even then it's no Problem to
   manually override the automatically
    set shutter speed. The scale for the
   manual override values can be found
   on the camera cover and rangesf rom
   +2lo -2exposure stePs. And You
   can adjust by half a step. ln thisway
   you have complete control even over
   subjects with an extremely high de-
   gree of contrast. We recommend a
   "minus" override (shorter exposu re
   time) for a small, bright object in
    front of a large, dark background

    against a very strong light in orderto
    better reproduce the detai ls ofthe
    dark objects. High-key effects, i.e.

    in-tone (diffuse light, fog or a snow
    landscape, for example), the end ef-
    fect of which is also a slight overex-
    posure, also require manual override
    ofthe exposure according to the ef-
     fect to be created. And those who
    enjoy experimenting can extend the
    override range by deliberately set-
    ting a wrong film speed.

SENSITIVE
VIEWING
 Pictu res that are th at little bit d ifferent catch the eye.
 Different in that they show something unreal, illogical
 orthought provoking, conveying an individual mes-
 sage. Considered use of a PRAKT|CAtrains the eye and
 the form and colou r receptiveness, even for off-beat
 photosthat aren't meant to be taken too seriously. The
 subtle language of colours and the discreet mood
 created bythe light imply a well-developed photo-
 graphic sense.
