GUIDE TO SELECTION OF EXPOSURE MODE
Viewfinder
Indication
Features
1. This is the ideal normal mode for snapshots and general photography.
2. When this mode is set the camera automatically decides both the shutter
speed and the aperture. Fully automatic exposures are possible over a wide
range of subject brightnesses.
3. You can concentrate on following the subject in the viewfinder without
worrying about exposure or shutter speed settings.
4. If you set an intermediate aperture on the lens, the program automatically
becomes a continuously variable program.
1. This is basically an aperture preferred mode, but it is possible to use it also
as a shutter speed preferred system. This mode is the one to select when you
want to put your creative ideas into the picture.
2. In this mode you can concentrate on special depth of field effects, adjusting
the aperture to determine whether the background, etc., will be blurred or in
clear focus.
Here the background is blurred to make the main subject stand out. (Wide
open lens aperture)
Here the background is also in sharp focus, giving a feeling of greater spa-
ciousness and expansiveness. (Stopped down aperture)
3. You can concentrate on shutter speed effects (blurring with motion, etc.).
Here a fast shutter speed arrests the movement of the subject, giving it a kind
of timelessness. (Wide open aperture)
Here use of a slow shutter speed results in a blurred subject, emphasizing the
sense of speed. (Stopped down aperture)
1. In Manual Mode, both the lens aperture and the shutter speed are set by
hand, giving free reign to your experience and 'feel' for the picture situation.
2. Use when you want to keep the same exposure settings regardless of the
brightness of the subject.
3. Use for "Bulb" photography when the shutter is both opened and closed
manually.
4. Use when you are basing the exposure on the values given by a separate
exposure meter.
