www.butkus.us Holding the Gamera 1. The basic method of holding the camera is used for taking pictures in the horizontal format. Grip the focusing ring with the left thumb and index 3 E-l finger and support the camera on the left palm. Place 'l the right thumb against the film winding lever and -*. wrap the other fingers around the body so that the index finger is on the shutter release button. Use the right eye for view-focusing. 2. For taking pictures in the vertical format, turn the camera aroLrnd, without any change in the basic hold- ing position, until the film winding lever is on top. ln both cases, press the camera against the f ace and both elbows (when possible) against the body, to steady the camera as much as possible. 3. For slow shutter speeds or with a telephoto lens, use a sturdy tripod, whenever possible. Screw a cable release into the socket of the shutter release button to release the shutter, as it will help eliminate camera vibration. Or, use props, like desk, chair, tree, etc., to support or steady the camera, as well as a bean bag (bag filled with beans) to absorb vibrations. 13View original page 18

Automatic Exposure Settings
Correct exposures are taken care of automatically when the TOPCON lC-1 is set on AUTO.
Correct exposure is the relationship between shutter speed and lens opening, as decided by the
brightness of the subject and is dependent on the film sensitivity. lt is one of the most important
factors for taking better pictures and also one of the most difficult adjustments to make, without
prior experience, in a non-automatic exposure camera.
Film speed is predetermined by the film loaded and the shutter speed is, usually, determined by the
action of the subject or the overall brightness. Therefore, the most important remaining factor will
be the ability to judge the brightness of the subject and set correct exposures based on such judg-
ments, both of which are automatically taken care of when the camera is set on AUTO.

Shutter Action
All interchangeable lenses prepared for the lC-1
have fully automatic lens diaphragm mechanisms
which means that you can view-f ocus at f ull
aperture and the lens diaphragm will automati-
cally close down to the required aperture, upon
shutter release, and then reopen back to the
maximum opening, after the picture is taken.
ln other words, pressing the shutter release
button means that the following actions take
place-
(1) Lens diaphragm starts to close down.
(2) Reflex mirror swings up.
(3) Lens diaphragm is stopped down to the
required aperture.
(4) The shutter curtains run across, taking the
picture.
(5) Reflex mirror swings down into viewing
position, ab the lens diaphragm opens up
fully for view-focusing at the full aperture.

is precisely controlled for meeting exacting
exposure conditions.

Manual Exposure Settings
The automatic exposure setting system of the lC-1 can be overridden very easily, in which case,
exposure settings can be set freely.
The exposure meter can still be used for taking exposure readings at shutter speeds from 1/500
to 1/B sec. but not at the slower shutter speeds, and B (bulb). Readings taken at 1/8 sec., however,
can be readjusted by stopping down the lens opening by the same number of steps as the exposure
time is increased.
Manual exposure settings are effective when the subject or point of interest is not centrally located,
or has too much contrast, or if a certain mood or effect is desired.

IMPORTANT
1. Although the exposure meter cannot be used
for readings at shutter speeds Il4 to 1 second,
and B (bulb), or the green-colored shutter
speeds, the aperture reading obtained with the
meter for 1/B second can be readjusted for
these speeds. ln other words, readjust the
aperture reading by stopping down the lens
opening by the same number of steps as the
exposure time is increased, or-
Shutter speed: 7lB-714-I 12- Aperture : 5.6- B 1 -1I-22 2. The exposure reading can be unsuitable even
when the exposure needle is not in the warn-
ing areas. This is so when a fast film is
used at a slow shutter speed or a slow f ilm is
used at a fast shutter speed.
Specif ically, the following combinations should
not be used :-
f 12 and I1725 sec. for ASA 320O film
f 12 and 1/60 sec. for ASA 1600 film
f 12 and 1/3O sec. for ASA BOO film

Depth of Field
1. When the maximum aperture is used for taking the
picture, it will be seen that objects before and
behind the main subject (or focused plane) will not
be seen as sharply focused as the main subject.
2. When a smaller lens opening is used, however, for
taking the same picture, it will be seen that some
objects before and behind the main point of interest
are also seen sharply. This zone of "apparent"
sharpness is the depth of field.
3. The depth of field is greater behind the focused Co mero-to-subiect
subject and shallower before but grows progressively I
equal as the focusing distance grows shorter. The
depth of field also grows greater as the focused
distance is increased and less as the camera-to-sub-
ject distance is decreased.
The d.epth of field also increases when the wide- - Foregroun d v*is shollower angle lens is used and decreases when the telephoto
lens is used.
