Edit history seems to be lost after moving photos from Timemachine
Hi: The bad news here is I'm a PC person and not a Lightroom or Mac person but am trying to help a friend with Lighrroom Classic (I'm pretty sure -- all his photos are stored on his machine -- that's classic, right?)
He is truly bad with computers (iMac Ventura 13.31) so I've helped him with LR before but my understanding, especially of LR tools & catalog file structure, is tenuous... . He had filled up his hard drive and got a friend to clear out junk. For unknown reasons, the other person then brought over all his images that were on Time Machine (did he delete original folders? Don't know), and put them in a new folder structure -- as near as I can tell, not the original structure he had in LR. I believe this transfer was not done from within LR (e.g. an Import?) but just drag & drop (or whatever TM does).
LR did, apparently, catalog the new folder structure and his photos show up there (thousands). However, only the edits & histories of TIFFs and those done with Sharpener (?) show the edits & history of edits. Nothing he'd done entirely within LR show, only the original image but without any change's he'd made.
He's got backups of his catalogs. How can he recover those edits? Everything is still on Time Machine (I assume). It's a 5T drive so isn't even starting to delete old stuff yet.
While I'm here, it might help me to understand how changes to a photo are stored in LR. I've tried to explain that the images he sees in LR catalog are only pointers to the original, which can be anywhere on his main drive but I don't think that's getting through. Are the changes/change log, though, within LR or do they accompany the original photo in its folder? If the latter, how does he access them?
I hope that makes sense. I really appreciate any help here. My buddy has been banging his head -- and my phone -- about this for a couple of weeks. He's a great landscape photographer (Sierra and Bay Area foothills weamerphotography.com) but not a computer wizard.
Grazie!
George
