# availablePhotoPixelFormatTypes The pixel formats the capture output supports for photo capture. ``` @property (nonatomic, readonly) NSArray * availablePhotoPixelFormatTypes; ``` ## Discussion To capture a photo in an uncompressed format, such as 420f, 420v, or BGRA, use the [`init(format:)`](/documentation/AVFoundation/AVCapturePhotoSettings/init(format:)) initializer to create your photo settings object. In that initializer’s `format` dictionary, pass the key , whose value must be one of the pixel format identifiers listed in this array. > Note: > Read this property only after adding the photo capture output to an ``doc://com.apple.avfoundation/documentation/AVFoundation/AVCaptureSession`` object containing a video source. If the photo capture output isn’t connected to a session with a video source, this array is empty. This property supports key-value observing. --- Copyright © 2026 Apple Inc.
