I can't save the depth effect into portrait photo

Today I found the secret way to save the photos as Portrait mode. The Photos app shows the Portrait tag for the image. But I can't save the blurred image and original one at the same time. I try to save them by using the type of PHAssetResourceTypeAlternatePhoto as Apple save the JPEG+DNG. There's no error but it only saved one processed image.

Is there any Apple stuff to tell me the way to save two images together as adjusted and the original ones at the same time?

What is the way you found to have Photos recognize the photo as a Depth Effect portrait?

Hi there,

Please, can you provide a sample code of how to save photos as "Portrait mode" ?

I think the way to save both files at once is to create a PHAdjustmentData object with your blurred settings, then save the original Photo with PHContentEditingOutput. This creates the second edited photo (with an E in the filename). With Image Capture, you can see the two files.

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{


    // Make a change request for adding an asset.
    PHAssetChangeRequest *changeRequest =
            [PHAssetChangeRequest creationRequestForAssetFromImageAtFileURL:originalJPEGFileURL];

    // Make a content editing output for use with the change request.
    PHObjectPlaceholder *placeholder = changeRequest.placeholderForCreatedAsset;
    PHContentEditingOutput *contentEditingOutput =
            [[PHContentEditingOutput alloc] initWithPlaceholderForCreatedAsset:placeholder];

    // Apply content adjustments to the newly created asset.
    contentEditingOutput.adjustmentData = adjustmentData;
    [adjustedJPEGData writeToURL:contentEditingOutput.renderedContentURL atomically:YES];
    changeRequest.contentEditingOutput = contentEditingOutput;

} completionHandler:^(BOOL success, NSError *error) {
    if (!success) NSLog(@"Can't create asset: %@", error);
}];

What I still need to figure out is how to get a saved photo to show up in the PHAssetCollectionTypeSmartAlbum. I don't know how to programmatically force it to show up in there. If I save a photo, edit it in Photos, and turn on Portrait, then it shows up in the album.

I found a few keys in the depthMetaData, but setting these didn't work: I found these keys in kCGImageAuxiliaryDataInfoMetadata

... xmlns:depthBlurEffect="http://ns.apple.com/depthBlurEffect/1.0/">

<depthBlurEffect:SimulatedAperture>4.5</depthBlurEffect:SimulatedAperture>

<depthBlurEffect:RenderingParameters>...

Use the EXIF tag kCGImagePropertyExifCustomRendered and set its value to 8 🙂

Hi Pippo,

How can I set this tag?

Thanks
