A configuration for defining bracketed photo captures in terms of specific exposure and ISO values.


class AVCaptureManualExposureBracketedStillImageSettings : AVCaptureBracketedStillImageSettings


The AVCaptureManualExposureBracketedStillImageSettings class is a concrete subclass of the AVCaptureBracketedStillImageSettings class used when bracketing exposure duration and ISO.

An AVCaptureManualExposureBracketedStillImageSettings instance defines exposure duration and ISO settings that should be applied to one image in a bracket. An array of AVCaptureManualExposureBracketedStillImageSettings objects is passed to captureStillImageBracketAsynchronouslyFromConnection:withSettingsArray:completionHandler: to specify the bracketing.

The minimum and maximum duration and ISO are query-able properties of the AVCaptureDevice instance supplying data to an AVCaptureStillImageOutput instance. If you wish to leave exposureDuration unchanged for this bracketed still image, you pass the value AVCaptureExposureDurationCurrent when creating the instance. To keep the ISO unchanged, you pass AVCaptureISOCurrent when creating the instance.
