exporting,importing same file
I'm starting to use iPhoto 11 more because my new OM-D produces such good JPEGs I no longer see a need for RAW and the attendant conversion issues.
I see that when I export an image from iPhoto to edit in Photoshop, and save the editing changes (overwrite the same file with the original file name), those changes do not automatically show up in iPhoto. But if I import the edited version into iPhoto and merge it with the original event, now there are two files with the same file name.
I understand that iPhoto uses a system that requires all versions of the original (master) to have the same file name or risk being lost?
What's the best practice to manage this (I assume the master can't be trashed?), or the easiest way to simply rename the edited file and keep both?
Thanks,
