Lost face data

Hi John,

I had not realised that the catalogue would act as a backup if the file data became altered so I think you are correct – there could be a bug. My only doubt is that other more experienced users would have been affected as well – this, perhaps sadly,  makes it more likely that it is me at fault. I have been scanning in old photos for some years using Adobe Elements which does not save all the metadata to the file. When I started using Lightroom, I thought I had re-catalogued all my photos using Lightroom: perhaps I missed some !

I will check photos that have been scanned in more recently (ie when I already had Lightroom) and see if the fault recurs.

Thanks for your insight.

All the best.

"I have found that if, at a later date, I go back to a photo, all the face names are still there as keyword tags but the face 'regions' on the photo can be randomly lost: some photos have a full set of face regions while other photos only have some of the face regions."

Do you mean that when you select that photo and do View > Loupe, and then click "x named people" in the toolbar at the bottom, some of the face rectangles no longer appear? If so, then this issue is independent of how LR writes metadata back to photos.  LR stores face information, like other metadata, in the LR catalog, and face information shouldn't disappear from the catalog unless you explicitly delete a face rectangle.

This smells like a bug, and you should file a bug report in the official Adobe feedback forum, where Adobe wants all bugs reported: https://feedback.photoshop.com/photoshop_family/categories/photoshop_family_photoshop_lightroom. (This is a user-to-user forum, and product developers rarely participate here.)

Thanks for getting back again. I am not sure what you mean. ExifWizPro only reads metatdata that is in a file - I add all the metadata using lightroom.

And  lightroom is  non destructive, meaning for ny metadataa including keywords you add, do not get ctualyy placed  in  the  original file. Some people keep that sidecar xmp file as you are to get around this, so the photo and the sidecar get opened  up, and if the app on the other end is xmp save, it combines the two.

However, if in lightroom you export the  photo, you get a new file with the edits including metadata included

Second up, Face Rec in Lightroom.

Now, I do not think Lightroom will use the extra metadata you placed into the images on your phone.

And unless your phone also reads the xmp file and is xmp savy, or is lightroom savy, it may not be showing you your lightroom metadata edits, unless you are talking about an exported image.

Thanks for that: I have never used plug-ins before but will give this one a try.

First up, an easy one, Lightroom does not show all metadata. Images have a lot more metadata than what lightroom shows.

To see more metadata when using lightroom, you do not need to go back to your phone. A simple plug-in exists to show the metadata. Jeffrey Friedl's Bloghas several nice plug-ins. Including Mettadata Viwer.:
