Metadata in DNG files not showing in Lightroom

[nantucketbob]

I add metadata to DNG files in Bridge.  The metadata is not show in the Lightroom file. However, I add metadata to DNG files in Bridge first, then develop the files in Lightroom, then export the DNG files as jpegs, and the metadata sticks.  If I add metadata later, it does not stick, will not export to jpeg files.  Very strange.

Adding metadata to DNG files using Bridge does not cause the metadata in LR to change. In Lightroom, you need to select the photos where you have changed the metadata using Bridge, then Metadata->Read Metadata from Files. You might want to consider a workflow where you add metadata using LR only, and then this need to perform extra steps in Lightroom goes away.

Thanks for the answer, dj_.  It works, of course.  But I find it really strange that Lightroom will not read data embedded in a DNG file without being prompted.  My workflow is: shoot in raw, convert to DNG, add metadata in Bridge, develop in Lightroom, convert to smaller jpegs.  The metadata from bridge has always appeared in the jpeg files. I will double check, but I never remember having a problem before yesterday.  I never even looked at the Metadata option, that is the option in the toolbar, not the one in the window beside Library Filter:

As stated above, I would recommend adding metadata in Lightroom from now on. This saves the step of forcing LR to read the metadata from the DNG files.

Lightroom works with a catalog where all metadata is stored. It does not read the metadata from your files to overwrite metadata that already exists in the catalog, unless you the human user specifically tell LR to do this.

Lightroom will add metadata if it’s present at import subsequent changes made outside of LR does not automatically. Doing so will also have the risk of altering/ replacing other edits you may have done in ACR outside of LR.
