Choosing Aperture (Aperture Priority Mode) - Olympus E-M10 Mark III Instruction Manual

Choosing aperture ( Aperture Priority mode)
A mode is a shooting mode where you choose the aperture and let the camera
automatically adjust to the appropriate shutter speed. Rotate the mode dial to A and
then use the rear dial to select an aperture value.
Larger apertures (lower F-numbers) decrease depth of fi eld (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 fi eld.
