How can I see Lightroom 12.3 collections in Bridge 13.0.3.693

[RJM-W]

I would like to find out how I can see Lightroom 12.3 collections in Bridge 13.0.3.693 and Bridge collections in Lightroom. Adobe Bridge is the best unknown, extremely useful programme. This is an interoperability question. I want to use the strengths of both programmes. Please help

As far as I know this isn't possible.

Lightroom and Bridge save the informations about collection on different place and in different formats.

In Lightroom the infos about collection stored in the appropriate catalog. Bridge create a text file in the file system.

Both apps can't read this informations from each other app

Bridge cannot access Lightroom Classic collections.

The best you could do is change your workflow to use keywords rather than collections.  If you set the LR option Catalog Settings > Metadata > Automatically Write Changes Into XMP, then keywords (and other metadata fields) can be shared between the two programs.  But if you make changes to such metadata in Bridge, you'll have to select the photos in LR and do Metadata > Read Metadata From File.

The two programs really aren't designed to be used concurrently on the same set of photos -- they have much different, mostly incompatible approaches to workflow.

Bridge is a browser, while Lightroom Classic is using a DAM (database), and as others have correctly answered, what you want isn't possible. Nor will it ever likely be possible.

As others have already stated, Lightroom Classic cannot acccess/use Bridge Collections and vice versa. It's also worth noting that LrC can be quite fickle about any external changes made to files, even when the changes are amde in one of Adobe's own products.
