I'm using lightroom 3 on mac. Not long ago I did save to catalog (I don't know what it does) and apparently I didn't select all the photos I have changed.
I opened the saved file and I've been asked if I want to close the software and to open it from this catalog. I pressed yes and I saw just the photos I'd selected before I saved the catalog. When I returned things to the last backup (from a week ago), I saw that all the changes I did from the last week were not there, even if I import a folder that I added in this week it comes up with no changes...
Is it possible to me to restore things to the second before i saved the catalog? when all the changed was there?
What does the save to catalog do?
