A Aperture Priority mode
In Aperture Priority mode, the camera automatically calculates shutter
speed according to the aperture value you choose. You can adjust the
depth of field (DOF) by changing the aperture value. This mode is useful
for taking portraits and landscape shots.
Large Depth of Field Small Depth of Field
In low-light settings, you may need to increase the ISO sensitivity to prevent
blurred photos.
S Shutter Priority mode
In Shutter Priority mode, the camera automatically adjusts the aperture
value according to the shutter speed you choose. This mode is useful
for capturing photos of fast-moving subjects or for creating tracer
effects in a photo.
For example, set the shutter speed to over 1/500 s to freeze the
subject. To make the subject appear blurred set the shutter speed to
below 1/30 s.
Slow shutter speed Fast shutter speed
In order to compensate for the reduced amount of light allowed by fast
shutter speeds, open the aperture and let in more light. If your photos are still
too dark, increase the ISO value.
