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.
