Using the Aperture Priority
Using the aperture-priority mode, you select an aperture and the camera
chooses an appropriate shutter speed to match the brightness. The main
purpose of using aperture-priority mode is to control the Depth of Field.
A higher aperture value brings the background out of focus. Selecting a
lower aperture value allows you to soft the background.
Using the Shutter Priority
Using the shutter-priority mode, you select a shutter speed and the
camera chooses an appropriate aperture value to match the brightness.
The main purpose of using the shutter-priority mode is to have a faster
shutter speed to freeze the action of fast-moving subjects or to have a
slower shutter speed to blur moving subjects in order to create a sense
of motion. Faster shutter speeds allow you to take a sharp picture of a
moving subject while slower speeds create a trail effect and allow you to
shoot without a flash in dark areas.
Using the Manual Exposure
Using the manual exposure mode, you can set both aperture and shutter
speed, and, therefore, you have complete control over the exposure
system, including exposure compensation.
Press the shutter button halfway, the difference between the standard
exposure and the selected exposure appears in red.
