Olympus STYLUS 1 Instruction Manual page 18

A aperture-priority mode
In mode A, you choose the aperture and let the camera
automatically adjust shutter speed for optimal exposure.
You can express the depth of field, and blur the background
intentionally.
• Larger apertures (lower F-numbers) decrease depth of field
(the area in front of or behind the focus point that appears to
be in focus), softening background details. Smaller apertures
(higher F-numbers) increase depth of field.
After setting the lever as the illustration shows, rotate the
3
control ring to set the aperture value.
• The shutter speed display will blink if the camera is unable to
achieve optimal exposure.
