DirectionsforUse
 The Leica-Meter  can be used in the hand, as well as
 attached  to  the camera.
   Turn  the inner disc to a position corresponding  to
 the A.S.A.  sensitivity of the film. This setting nted
 only. be changed when a film of different  sensitivity  is
 used in the camera.
Measurement
V   Measuring Rangc  I
 The  light  entrance window  of the meter  is directed
 toward-s the  subject and  the marking    V  on  the
 outer  knurled  scale is turned  opposite  the black  or
 white channel parallel  to and a6ove the needle. This
 will automatically set the required F stop as well as
 the correct exposure time.

V   Measuring Range II
 Under poor light conditions, the baffie lever is flipped
 forward  (-see illustration  page 3 )  is turned  to posifion
V    and  the  marking  V   on  the  knurled  scale
 ring   is brought  parallel  to and above   ttl,e needle.
 Pointing the triangles directly  at the needle will  give
 incorrect reading.

V   Measuring Range IIL
 (Necessary  only-for   poor  lighting  conditions.)   After
 the  super-sensitive element has been  insert6d.  the
 index mark   V    is used  in  the same way-becomesai  de-
 scribed  above.  Position   of   the   lever
 immaterial.
  Take care not  to cover up the  light entrance win-
 dow. The  appropriate  F  stops and exposure times
 can still be read off even aftei the Leica-Meter is no
 loqqer pointed  to the object to be photographed.
  The Leica-Meter has a zero-set adjustment to com-
 pensate for  pgssible changes in the zero position  of
 the needle. The  slotted screw which  is underneath
 the mounting shoe can be turned with a small screw
 driver  either  to the  right  or  left, so that the needle
 will come to rest on zero. The exposure meter has to
be he-ld level and the light  entrante window must be
 cover'ed.

       The Leica-Meter  is so designed that   it  slips into  the
        range-viewfinder _clip of practically  all modern types
          oI  cameras.  It  does not,  at  tltis  tinze,  fit  into  the         Imarect  Finder.
         The  shoe  has  standard  dimensions,  However.
       Lometimes the rangefinder clip on the camera is a
           Ilttle large or small so that the Leica-Meter docs llot
              fit properly. A^ny_repairman can adjust-    this by press-
         ing the rangefinder clip together.
        _ To  take  into  account  the  position  of  this  range-
         finder -clip on various camera models, the shoe ol  tlre
        Leica-Meter can be removed by looseiring two screws,
                            and  it may be repositioned
                               as required  in  different  sets

         into  the Leica-Meter  through  the open screw holes.
  Careand}|andling
        Your- ,exposure meter   i-  a precision  lnstrument.    It
        should receive the same car-eful handline  and  treat-
       ment that are given to an expensive camera or any
         fine precision  instrument.  Your  meter has been as-
       sembled with  a watchmaker,s  skill and should  not,
       under any circumstances, be tampered with  or taken
         apart.
         _Several  general  precautions  must  always  be
        observed.

Extreme Temperatures
-femperaturesYour  meter shouldin excessnot beof subjectednormal atmospherlcto extreme heat'con-
Aitlohs (130'F) may be injurious to the photovoltaic
cell.--Due
         to  its hermetically sealed construction, the cell
is noi  affected by low iemperatures and  is resistant
to moisture.
Care ol Lens
Avoid scratching the lens, or allowing dust to accu-
mulate on  its surface, which  will  hinder the trans'
mission of  light.
Exposure lor Black and White Outdoors
The meter  is read when pointed toward  the subject
from the camera position,  in the same man-ner as you
 ooint'oractiiallvvour camer-a. This technique  is satisfactory  for
                 all outdoor scenes. The main exception  is
 where thd brightness in the background, as viewed by
 the meter,  is widely  difterent  from  that  of the -princi-
 pal subieit. Examples of such scenes are back-lighted
 Subiecti and dark-subjects against light backgrounds'
 Fof these scenes, the'exposure should be measured
 by taking a close-up reading on the actual subject or
 a similar substitute subject.
    In makins a close-up reading, the meter is actually
 held as neai to the subject as convenient. (Be careful
 not  to measure the shadow cast by the meter.)  Al-
 though the brightness of a subject is independent of
 dista-nce, the meter can  indicate  that  brightness so
 lons as it sees onlv the particular subject: hence, it is
 held close to smali subj-ects, but may be held propor-
 tionately  farther  from  larger surfaces. _
   As  a- substitute  of  corresponding  reflectance, the
 palm  of  the hand  is  often  convenient. A  close-up
 ieadins.  with the meter held about four inches from
 the ha-nd, will give dependable exposure for average
 scenes. If  the  subjecf  is  in a shadow,  the hand  is
 held in the shadow of the bodY.
 Exposure lor Color Outdoort
 Color  photography  requires the exact measurement
  of exposure ih ord-er to obtain  faithful  reproductions.
  Closd-up reading on the principal  parts  of the subject
  usually gives the most accurate exposure.
   The lishtness or darkness of a color transparency
   is contrdled   by  the exposure,  but  within  the  film's
