Setting ISO speed

Raise the [ISO speed] to use a fast shutter speed when you wish to reduce the effects of camera shake or avoid blurry subjects, or to turn the flash off when shooting in a dark area.

Shooting modes in which the ISO speed can be set

Caution

Raising the [ISO Speed] increases the shutter speed and allows the flash to reach subjects at far distances. Therefore, it is possible to shoot images with less subject blur or camera shake even in dark places.

However, the higher the [ISO Speed], the more the noise stands out (more uneven areas in an image).

Lowering the ISO speed results in sharper images, but there may be an increased chance of image blurring in certain shooting conditions.

When the camera is set to [ISO AUTO] (), you can press the shutter button halfway to display the automatically set ISO speed.

The following explanations are provided based on the assumption that the [Shooting Mode] is set to [Program AE] ().

1. Press the ⋖Power⋗ button on the camera.

2. Press the ⋖FUNC./SET⋗ () button.

3. The following screen appears on the LCD monitor.

Operate the ⋖directional buttons⋗ up or down to select an [ISO AUTO] ().

Operate the ⋖directional buttons⋗ left or right to select an [ISO Speed]* of your choice.

* The appropriate [ISO Speed] differs depending on shooting locations. If the camera shake warning icon () appears when you press the ⋖Shutter Button⋗ halfway, it is recommended to gradually raise the ISO speed in increments such as [ISO 80], [ISO 100], etc., and then set the [ISO Speed] when the camera shake warning icon () disappears.

Changing the ISO speed
	Automatically adjusts the ISO speed to the Shooting mode and shooting conditions.
*	Fine weather conditions, outdoor shooting.
	Cloudy, Twilight
	Nightscapes, Dark interiors

* For the PowerShot A800, the setting is not available.

4. If the following icon is shown, the setting is complete (if setting [ISO Speed] to 400).

The shooting modes in which the ISO settings can be made are as follows.

Caution

With [Low Light] () you can set an even faster speed.

In [Low Light] mode, depending on the scene, the [ISO speed] is set higher and the shutter speed is set faster than in [AUTO] () mode so that you can shoot in dark places with reduced camera shake and subject blur. This mode is recommended for shooting in candlelit or similarly lit scenes.

When [Low Light] mode is set, recording pixels are fixed to () size.
