LightroomCC/6: It is not possible to transfer the data from face recognition and tagged faces to another Lightroom catalog. Already asked the support by chat. This is a very ugly, if you have to tag all previous tagged faces again.

Hi Victoria,

I have one Lightroom Catalog where many people are tagged by face detection feature already. It took quite some time to manage, but after ~ 3hours the detection went well and nearly all relevant persons were tagged.

Now I created a new catalog to manage newer pictures and have to start from zero with face detection even if 90% of faces are already in the older catalog.

It would be nice if it would be possible to save the already known faces at one common data storage and be able to use it for several catalogs.

I asked the Adobe support by chat, but they told me that it is not possible yet and I shoud report this here as a missing feature.

In between, I already thought about a workaround to save one picture of each person on a common path and import this path on several catalogs, just to get the tagging, but it seems not to work.

Best regards,
Martin

I'm with you. That's not likely to change, but let me ask a different question - why do you need multiple catalogs? What's preventing you from keeping all of the photos of these people in a single catalog?

One catalogue at my iMac (with lots of storage) and one on my MacBook with a limited ssd

There are several ways where you can do this. It all involves transferring a subset of photos with tagged faces that you are interested from your first catalog to the new one:

Catalog export/import approach:
1. Goto People view, select the named faces that you want to transfer to the new catalog. Notice the respective photos are also selected in the filmstrip.

2. Export the selected named faces and photos to a new catalog

3. Enable indexing for the new catalog and do some clean up to remove any faces that you do not want. You don't need many examples of the same face for the new catalog.

4. Use the new catalog as the base to start a new catalog or import it into another catalog that you already have.

Metadata export/import approach:
1. Goto People view, select the named faces that you want to transfer to the new catalog. Notice the respective photos are also selected in the filmstrip.

2. Export the selected photos as JPEGs (In the export Metadata option, don't remove personal info). The faces aces info will be exported along with the image data. The size of the exported JPEGS does not matter, as long as the face thumbnail quality is acceptable to you. 1024 pixels on the long edge or larger is recommended.

3. Import the exported JPEGS into your new catalog. Lr will gladly imported the already tagged faces into your new catalog.

5. Enable indexing for the new catalog and do some clean up to remove any faces that you do not want. You don't need many examples of the same face for the new catalog.

6. Use the new catalog as the base to start a new catalog or import it into another catalog that you already have.

Either way, that will seed your new catalogs with faces that you already tagged.

Thank you very much.

This works at least as a good workaround to me.

@Victoria: I use several catalogs, as the raw files older than a few monthes are on different external hard drives which are not connected at same time.

You realize the photos can all be in a single catalog, even if the photos are offline? The catalog just needs to be on a drive that's available at all times - and that doesn't have to be the same drive that holds the photos.

I struggled with this for days, but found the solution.

If you convert your files to DNG, you can then Command+S to save metadata to these files. Now all facial recognition data, including the tagged areas, will be perfectly preserved when importing to other catalogs.
