A configuration for defining bracketed photo captures in terms of bias relative to automatic exposure.


class AVCaptureAutoExposureBracketedStillImageSettings : AVCaptureBracketedStillImageSettings


An AVCaptureAutoExposureBracketedStillImageSettings instance defines the exposure target bias setting that should be applied to one image in a bracket. An array of AVCaptureAutoExposureBracketedStillImageSettings objects is passed to captureStillImageBracketAsynchronouslyFromConnection:withSettingsArray:completionHandler: to specify the bracketing.

The minimum and maximum exposure target bias are properties of the AVCaptureDevice instance supplying data to an AVCaptureStillImageOutput instance. If you wish to leave exposureTargetBias unchanged for this bracketed still image, you may pass the value AVCaptureExposureTargetBiasCurrent.

class func autoExposureSettings(exposureTargetBias: Float) -> Self
