A-MODE – APERTURE PRIORITY
The size of the aperture (lens opening) determines the depth-of-field
in the final image as well as the intensity of the light falling on the
film. Depth-of-field is the range in front of and behind the focus point
that appears sharp in the final image. In the viewfinder, only the
plane the camera is focused on will appear sharp. The photographed
image however, will have a depth-of-field corresponding to the
selected aperture.
Large apertures (small numbers) limit the depth-of-field to a narrow
range in front of and behind the point of focus. Set a larger aperture
when photographing portraits to make your subject stand out from
the background.
Small apertures (large numbers) provide greater depth-of-field. Set a
small aperture when photographing landscapes to ensure your entire
scene is sharp.
• Usable apertures will depend on the aperture range of the lens you are using.
