Ideal Direct Reading Meter User manual

EASIEST TO USEI

The IDEAL Direct-Reading Photo-Elecric LIGHT
METER is by far the simplest and easiest-to-use.
Just hold the Meter up to the subject, facing the
camera. Instantly the Nf eter shoq's the best lens
setting directly in f-stops.
No guess-work or computing, no "light values" to
interpret. A child can use this Meter as well as an
expert photographer.
The IDEAL EXPOSURE METER is a true incident
light photo-electric meter. That means it measures
all light that falls on the subject, not just reflected
light. Experts consider incident light the most accu-    i
rate and dependable method of insuring correct
exposure.                                                                              1
This Manual explains how the Meter helps get per-
fectll' exposed pictures every time, u'ith:
                                                        ?
   Any camera    |d6yie, still, or box type.                   -   Any lens                   Fast, slow, telephoto, etc.                                                    {llL               -   Any film    Color, or black-and-white.               -
Any shutter speed, indoors or outdoors, daylight
or artificial light, whenever there is light enough to
take pictures with your equipment.

   Just hold the Merer up to the subject's face, or the
  main object, with Meter facing the camera.
   Pointer indicates correct f-stop for the lens on the  outer         ring.
  Do not''ellowshaJe oi cover the Collecter Lens over the
   photocell. Be sure Shutter Time and Film SpeeJ
   settings are correct as described on page 4.

Turn the knob in back of Meter until Shutter
Time you want is opposite ASA film speed of
the film you use. This single adjustment in-
stantly matches the Meter to your camera and
eliminates all further calculating. This setting
need not be changed until you wish to use a
different shutter time or film speed.
Film Speeds of commonly-used lilms    See page ll.Shuttei time    Movie Cameras use-  Cine/25 fornormal speed -(t6 frames), 1./1.0 for fast motion (8
frames) 7/50 for slow motion (32 frames). These
values are approximate, but close enough for excel-
lent results. Box cameras and folding cameras with
only a single shutter speed use Cine/25. Cameras
with adjustable shutters use Cine/25 or I/50 for
ordinary snapshots, with slower shutter speeds for
posed pictures in poor light, and higher shutter
speeds for pictures of moving objects or people in
good light or with fast lens.

     Just hold Meter up close to subject's facq or to the
    main object, with Meter facing the camera, so that
    same amount of light falls on the Collector Lens as
   on the subject. The pointer indicates correct lens
      setting. Be sure Shutter Time and Film Speed settings
    are correct. If  indicated setting calls for a larger
     f-stop than maximum camera lens opening, move
     iights closer or increase illumination, or use slower
     shutter soeed.

    ACCURACY  The IDEAL Exposure Meter  is
       carefully tested and calibrated to gfue perfect expos-
       ures. However, all mete.rs are affected bv errors in
         the- marking or rating of camera shutters, filni speeds,
     and lenses.
      For example, camera shutter speeds may actually be
      slower or faster than their markings. Film speed is
        affected by age of the film and by me-thods of divelop-
      ment. Lenses vary if they have been coated, or aie
      dusty behind or between elements, or if the cement
      between lens elements has become cloudy. Often
      these errors cancel out, but they may add up and
      cause under- or over-exposufe, no matief what-expo-
      sure metef is used, if not compensated  for.
      The rem,edy is ve{y simple with the IDEAL Exposure
       Nleter. If your first pictures are under-exposed or      over-exposed, just make
     your Meter film speed
       setting a little lower (for
     more exposure) or high-
     er (for less exposure)
       than the rated film speed
       until the exposures are
      "on the nose."

PROPER CARE OF YOUR METER
6r-

 The.IDEAL Exposure Meter is carefully constructed
  to give many years of excellent service if treated with
  the care that a sensitive instrument deserves. TREAT
 IT AS YOU \UTIOUID A GOOD WATCH.
 Do not store Meter close to other meters. All expos-
  ure meters contain strong magnets, which are weak-
 ened or affected by the lontinued presence of other
  magnets.
 No zero adjustment is necessary with the IDEAL
 Exposure Meter. Slight variationi of the zero point
 do not appreciably affect the Meter's accuracy.
 No compensation  is necessary for light or dark back-
 grounds or for telephoto or wide-angle lenses.
  Filters are rated 2X, 3X, 4X, etc. If you use a filter,
  increase the exposure as many stops as the number
 in its "filter factor" rating.
 Inexpensive cameras often have one, two, or three
  "hole" stops. The No. 1 stop (largest hole) is usu-
  ally f-t6, No. 2 is f-22, No. 3 is f-jz.
 Do not point the IDEAL Exposure Merer at the sub-
  ject, or hold horizontally or use otherwise like a
  reflected-light typ. meter. The IDEAL Exposure
 Meter is an incident-light meter and should bb held
  only UP FACING THE CAMERA with the same
  light falling on the Collector Lens as on the subiect."

3-YEAR SERVICEI CGUARANTEE
    The IDEAL Exposure MMeter is carefully
      constructed and tested. an<and will give many
      years of excellent serviceice if used with the

     or fine camera.
      This Meter is guaranteeded  ragainst defects in
      material and workmanshir;hip for a period of
      three years from date of'of purchase. Should
      your meter fail to operateate properly, pack it
