M: Manually Setting the Shutter Speed and Aperture
You can manually set the shutter speed and aperture to achieve a particular effect. This is convenient for shooting fireworks and other images where it is difficult to set the correct exposure automatically.
- Turn the shooting mode dial to M (Tv and Av not available on PowerShot A530).
- The shutter speed and aperture value appears on the LCD monitor if it is on.
- Select a shutter speed using the left or right button.
- Press the <FUNC./SET> button.
- Select an aperture value using the left or right button.
- Shoot the image.
- When you press the shutter button halfway, a number indicating the difference between the standard exposure* and the selected exposure appears on the LCD monitor. If the difference is more than 2 steps, '-2' or '+2' appears in red.
* The standard exposure is calculated by the AE function according to the selected metering mode.
- If you wish to change the exposure, select the shutter speed or the aperture with the <FUNC./SET> button and change the value using the left or right button.
- The LCD monitor's brightness matches the selected shutter speed and aperture value. When you select a fast shutter speed or shoot a subject in a dark place and set the flash to (Red-Eye Reduction, Flash On) or (Flash On) the LCD monitor will always light up.
- The aperture value and shutter speed change according to the zoom state as follows.
