If I remove a raw image from my catalogue and then come back a few days latter and bring it back again, I find that all my edits have been lost. Other than exporting the file, is there a way to preserve my edits to raw files even when the file is removed from my catalogue? I have read that Aperture 3 allows you to do it. With LR5 being a more advanced application, I assume this can also be done but I don't know how. Thank you.
