if optimise mac storage is on will photobook use originals or low res?
I would like to save space on my Macbook Air and since my photos take lots of space, i thought of turning on Optimise Mac Storage in Photos as i do on my Phone. But when i create a project from the photos, i'm not sure whether it will use the originals or low res photos, I'd like it to use the originals. Any idea about that?
MacBook Air (13-inch Late 2010), OS X Yosemite (10.10.1)
