A Boolean value indicating whether the capture output supports automatic red-eye reduction.
- iOS 12.0+
- Mac Catalyst 13.0+
In iOS 12 and later, AVFoundation applies a red-eye reduction effect only when needed. It won't apply red-eye reduction in the following situations:
When you force a flash capture in good light
When only one eye is visible
When doing a bracketed capture
When taking a picture with depth on the dual camera
When taking RAW + processed (JPEG or HEIC) still-photo capture with auto red-eye reduction enabled, AVFoundation applies correction to only the processed photo, not the RAW photo.
