Can someone help me? Today while attempting to add a single key word to about 400 images, I ended up deleting all the key words! I did not notice this had happened until many hours later. These 400 images were in different places so were key worded by location and what was in the image. I just wanted to add one key word, the city these locations were found in. Didnt work as now all key words are gone.
How can I recover all this lost information? I have a Lightroom catalogue back up but have never needed to use it before. Is there any easy way to get all those key words back there?
I'm using LR4 on a Mac.
