•Understanding How ASM Works
Using the Aperture Priority
In 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 soften the background.
Using the Shutter Priority
In 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
Under 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.
