LR doesn't have the ability to automatically find missing photos by capture time. A couple of options:
- Find the missing photos manually, one at a time. Tedious, but should take a few hours at most.
- If you're experienced with scripting, you could use the List View plugin to produce a list of photos with the filename recorded in the catalog along with their capture times. You could then use Exiftool to produce a list of the photos with their current filenames and capture times. Then you could combine the two lists to make a script that renames the files back to the filenames recorded in the catalog. But even if you're experienced scripting, this could easily take as much time as the manual method (or more), though it might not be as boring.
Oh man, i did manually. Horrible experience... =S
I dont understand nothing about scripting...
Now stay the tip for adobe to make find similar by capture time
