Setting ISO speed (PowerShot ELPH 310 HS / IXUS 230 HS)

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.

Caution

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

Raising the [ISO speed] results in a faster shutter speed, reducing image blurring and letting the flash reach greater distances to the subject. The images, however, will appear coarse.

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

To set the [ISO Speed], it is necessary to set the [Shooting Mode] to one of the following modes.
