                    updating

Tells if a setting value has been changed and is waiting for change confirmation.

Declaration

Swift

var updating: Bool { get }


                    
                    
                    supportedModes

Supported exposure modes.

An empty set means that the whole setting is currently unsupported.

Declaration

Swift

var supportedModes: Set<CameraExposureMode> { get }


                    
                    
                    supportedManualShutterSpeeds

Supported shutter speed manualShutterSpeed and manual mode.

Declaration

Swift

var supportedManualShutterSpeeds: Set<CameraShutterSpeed> { get }


                    
                    
                    supportedManualIsoSensitivity

Supported iso sensitivity manualIsoSensitivity and manual mode.

Declaration

Swift

var supportedManualIsoSensitivity: Set<CameraIso> { get }


                    
                    
                    supportedMaximumIsoSensitivity

Supported maximum iso sensitivity values.

Declaration

Swift

var supportedMaximumIsoSensitivity: Set<CameraIso> { get }


                    
                    
                    mode

Current exposure mode.

Value should be considered meaningless in case the set of supportedModes is empty.

Declaration

Swift

var mode: CameraExposureMode { get set }


                    
                    
                    manualShutterSpeed

Shutter speed when exposure mode is manualShutterSpeed or manual mode.

Value should be considered meaningless in case the set of supportedManualShutterSpeeds is empty. Value can only be changed to one of the value supportedManualShutterSpeeds

Declaration

Swift

var manualShutterSpeed: CameraShutterSpeed { get set }


                    
                    
                    manualIsoSensitivity

Iso sensitivity when exposure mode is manualIsoSensitivity or manual mode.

Value should be considered meaningless in case the set of supportedManualIsoSensitivity is empty. Value can only be changed to one of the value supportedManualIsoSensitivity

Declaration

Swift

var manualIsoSensitivity: CameraIso { get set }


                    
                    
                    maximumIsoSensitivity

Maximum Iso sensitivity when exposure mode is automatic.

Value should be considered meaningless in case the set of supportedMaximumIsoSensitivity is empty. Value can only be changed to one of the value supportedMaximumIsoSensitivity

Declaration

Swift

var maximumIsoSensitivity: CameraIso { get set }


                    
                    
                    autoExposureMeteringMode

Current auto exposure metering mode..

Declaration

Swift

var autoExposureMeteringMode: CameraAutoExposureMeteringMode { get set }


                    
                    
                    set(mode:manualShutterSpeed:manualIsoSensitivity:maximumIsoSensitivity:)

Changes exposure mode, manualShutterSpeed, manualIsoSensitivity and maximumIsoSensitivity.

Declaration
