Big Sur Photos does not export image Titles as metadata

I am having the same problem -- title, keywords & caption do not export with photo in spite of checkbox.

It does not work for me even with all the ticks checked (please see my lengthy answer below)

Same problem here. I'm using Big Sur and exported photos keep the date and location info I added, but not the title, keywords, or captions.

Is Apple working on a fix?

Thanks for the link Old Toad. I reported the issue as well.

A good idea, but that would be a problem, if the title is very long or does contain characters that are not alphanumeric, like commas. It may be causing problem in the Finder. And the original filename will be lost. At least I would prefix the title with the original filename.

It will be a long wait for a fix. I just installed the current Beta version and it is still not fixed. Photos is including the description and the location, but not the title, when exporting JPEGs. I would copy the title to the description before exporting. The description I currently more important on Apple devices than the title, because iPhones with iOS 14 and iPads with iPadOS 14 can show the description of a photo but still not the title.

I am using this Apple Script to copy the titles to the descriptions: Script: Batch Change the Description to the Title plus the Current Description (Caption)

Big Sur Photos.app 6.0 exports .tif Title, Captions and Keywords OK to both IPTC and XMP tags:

exiftool -a -G1 -s export.tiff
[IPTC]          ObjectName                      : Title text.
[XMP-dc]        Title                           : Title text.
[IPTC]          Caption-Abstract                : Caption text.
[XMP-dc]        Description                     : Caption text.
[IPTC]          Keywords                        : Keyword 1, Keyword 2
[XMP-dc]        Subject                         : Keyword 1, Keyword 2

But it exports only the Caption text and puts it in the AFAIK wrong 'IFD0:ImageDescription' tag (that Preview.app however manages to display):

exiftool -a -G1 -s export.jpeg
[IFD0]          ImageDescription                : Caption text.

Exporting unmodified originals with IPTC as XMP exports the updated metadata Dates, Titles, Captions, Keywords, locations as a sidecar file:

exiftool -a -G1 -s export.xmp
[XMP-exif]      GPSLongitude                    : 31 deg 8' 6.36" E
[XMP-exif]      GPSLongitudeRef                 : E
[XMP-exif]      GPSHPositioningError            : 1 m
[XMP-exif]      GPSLatitudeRef                  : N
[XMP-exif]      GPSLatitude                     : 29 deg 58' 36.84" N
[XMP-exif]      GPSDateTime                     : 2020:12:22 09:31:56Z
[XMP-dc]        Title                           : Title text.
[XMP-dc]        Description                     : Caption text.
[XMP-dc]        Subject                         : Keyword 1, Keyword 2
[XMP-photoshop] DateCreated                     : 2010:10:16 17:19:13+03:00
[Composite]     GPSLatitudeRef                  : North
[Composite]     GPSLongitudeRef                 : East
[Composite]     GPSPosition                     : 29 deg 58' 36.84" N, 31 deg 6' 6.36" E

Those can be easily joined with GraphicConverter (it currently copies the tags to old IPTC that Photos.app 6.0 needs and also new XMP that Photos.app 6.0 ignores. It also copies the modified dates apparently from the 'XMP-photoshop:DateCreated' tag):

GraphicConverter > IPTC/XMP menu > XMP Sidecar File > Copy into JPEGs, TIFFs, PNGs, webp, HEICs

Or via exiftool (IPTC and modified date would need additional options):

exiftool -m -P -overwrite_original_in_place -ext jpg -tagsfromfile %d%f.xmp .

<sigh>

Good idea for titles -- thanks. Sadly insufficient for keywords or captions :-/.
