# init(rawPixelFormatType:)

Creates a photo settings object for RAW-format-only capture with the specified pixel format.

## Declaration

```swift
convenience init(rawPixelFormatType: OSType)
```

## Parameters

- `rawPixelFormatType`: The Bayer RAW pixel format type to use for capture. This value must be one of the format identifiers listed in the doc://com.apple.avfoundation/documentation/AVFoundation/AVCapturePhotoOutput/availableRawPhotoPixelFormatTypes-5fatm array of your photo capture output.

## Return Value

Return Value A new photo settings object.

## Discussion

Discussion Use this initializer for RAW-only capture. To capture an image in both RAW format and a processed format (such as JPEG), use the init(rawPixelFormatType:processedFormat:) initializer instead. Requesting RAW format capture adds requirements for other photo settings: for details, see the rawPhotoPixelFormatType property. The capture output validates these requirements when you call the capturePhoto(with:delegate:) method. If your settings and delegate don’t meet these requirements, that method raises an exception.
