Remarks

You can find out if a device supports this control by checking IsoSpeedControl.Supported.

You can access the IsoSpeedControl for the capture device through MediaCapture.VideoDeviceController.

The IsoSpeedControl enables apps to manage the ISO speed settings on a device. For example, in low-light conditions, apps may prefer higher noise level in return for higher overall brightness. The ISO speed control lets apps adjust tradeoffs such as this.

Use SetPresetAsync to set the ISO level to one of the IsoSpeedPreset values.

SupportedPresets lists the preset values that are support on the device.

For how-to guidance for using the FocusControl, see Manual camera controls for photo and video capture.
