Argus C44/C44R Manual: Setting the Shutter
Turn
the shutter speed dial until the destired number is exactly opposite
the index mark, not in-between. The numbers shown are fractions of a
second.
The shutter speeds that can be used depend on the film
you are using and the light on the subject, but as a general guide, try
to use 1/125 or 1/300 for pictures of moving subjects. If you use 1/30,
1/15 or 1/8, use a tripod or brace the camera against a firm support.
'B'
stands for 'bulb' and is used for time exposures. When set on 'B', the
shutter will remain open for as long as the shutter release is held
down. For best results, use a cable release and tripod for time
exposures.
The
aperture setting determines the amount of light that comes through the
lens. The smaller the aperture number (known as 'f-stops') on the dial,
the more light comes through the lens. The aperture dial can be set
in-between the marked numbers if necessary.
50mm lenses were
made with maximum apertures of 1.9 and 2.8. As you go up the scale
above 1.9 or 2.8, each higher number lets in one-half as much light as
the previous one.
The aperture setting also determines what
range of distance will be in sharp focus in your picture -- known as
'depth of field'. At the smaller-numbered f-stops (1.9, 2.8, 4), the
range of sharp focus will be shorter -- objects in front of and behind
the subject you focus on won't be as sharply focused as the subject.
With the larger-numbered f-stops (11,16, 22), objects in front of and
behind the subject will be in sharper focus.
