How do you export original files from Photos?
I tried out the Photos app again - following thread suggesting that this app would import filtered photos from an iPhone. It doesn't, it suffers the same issue as iPhoto. So, I'd like to copy my photo out of Photos and back into a more functional library. How does one do this. Worryingly, when you do Apple/Shift/E for export, there are only options for compressed modified files, not originals.
