Since I upgraded to Lightroom CC, I'm having an issue with suspected duplicate photos and photos getting mixed up within Collections.
Here's the problems:
Has anyone else encountered this problem? I'd appreciate any help.
I don't know about #1, other than to say there are many reports of Lightroom mis-identifying duplicates, or not identifying duplicates.
For #2, try deleting your preview cache. With Lightroom closed, go to the same folder as your Lightroom catalog and delete the folder whose name ends with Previews.LRDATA. Do not delete anything else.
Ok thanks, will give that a try.
