iso
The current exposure ISO value.
Declaration
var iso: Float { get }Discussion
This property controls the sensor’s sensitivity to light by applying a gain value to the signal. This value is between the active format’s minISO and maxISO values. Higher values result in noisier images.
To set the ISO, call the setExposureModeCustom(duration:iso:completionHandler:) method.
This property is key-value observable.
