I have missed this basic LR ability and don't see how to set LR so that Bridge can read the data. When I make an adjustment in LR, Bridge does not see it. I have set Catalog Settings/Metadata to Offer Suggestins.../Write Develop settings../Automatically write changes into XMP. I have folder of .cr2 files from my camera and I do indeed see two .xmp files within but I'm not sure what I had set to get them there because the above settings are not working for other files I develop in LR in such a way as to allow Bridge to see them.
I see that opening the folder within Bridge creates .xmp files within the folder for each of the files and it honors the changes made in LR. Somehow a few of the .xmp files made in LR were set within the .xmp files in that folder but not others. Any tips? I've looked at the LR help file...
I have found some challenges with my workflow, apparently from how LR and Bridge regard the .xmp files. I'm trying to confirm the exact behavior but from what I can tell these are circumstances that present a challenge.
Lightroom will update a .xmp file as long as no other editor has made changes to the file. If you have made changes with ACR, then it seems LR will then not overwrite changes made in LR to the .xmp file even if you have LR set to do so. You can force LR to write the changes into the .xmp by choosing Save Metadata to file. It will actually confirm you want to overwrite the other applications changes to this file.
As far as LR is concerned it seems to write all changes to any .xmp file that hasn't been modified by another editor, but it doesn't read any changes made using an external RAW editor, since it stores it's own changes inside it's database. Here again you can use the Read Metadata from File menu command to read in the .xmp file that you have modified in ACR and sync those with LR's internal settings.
It has me a little confused right now, and I"m still trying to understand exactly what happens when. I really like using a smart layer inside photoshop, but it appears it requires some babysitting to make sure any changes made in ACR get back into the LR library.
