I'm currently debating what to do with my photo collection. As of this posting, my Lightroom 4 catalog has 14,711 photo's going back to 2007. The majority of these are RAW files that have been fully processed, tagged and rated. Side note, I switched to Lightroom back in Aug. 2011 from Bibble 5 Pro. I had Bibble write metadata to standard xmp files, which Lightroom has mostly read. Going back through earlier photo's however, it appears that some of the tags are gone or not tagged correctly. Since this is only on photo's that were originally tagged in Bibble, I'm guessing that's the issue. I've begun to go back and fix everything in Lightroom. This made me question why I'm keeping thousands of pictures in RAW format that for 98% of them, I will never go and reprocess. Being that my laptop is due for replacing and I'm seriously considering going back to a full time linux distro (MacBook Pro now, but I don't love Apple's new 'disposable' laptop policy and not being able to upgrade anything). Switching will require a new RAW editor, which I'm fine with, but it again points to my dependance on Lightroom. If I don't process those pictures as JPEG, then they will be unprocessed and potentially have more tagging issues if/when I do switch to something besides Lightroom. So after a long winded explanation, I guess my question to you is... Do you keep your RAW files after you process them? I'm seriously considering keeping only my favorite RAW images (a few hundred or so) so I can mess with them later, but converting all of the rest to high quality jpeg's and dumping those RAW's. Anyone have any thoughts on this? I'm thinking long term down the road, where I don't know what OS/software combination I'll be using, but want the pictures easily accessible and searchable.
