LR suggested at one photo that the metadata has been changed and if i wanted to update it. I was about to export the photos in that specific collection so all were selected at this moment. as i said yes to update it from the disk LR started updating all files in the folder. i managed to cancel the operation but it already changed the metadata at least in 30 pictures. hence all went back to original and i lost the edits i made.
Is it possible to get back the edits?
ps: The catalog has been backed up today and i did only a few little edits since so i dont care if I loose those but the 30 edits are hurting a bit.
If you made a backup before this happened, you can open the backup catalog in LrC, and find the collection in the there (which should have the proper metadata). From there, it's up to you if you want to use the entire backup catalog, or just that one collection.
