Hi everyone. As my workflow increases, and my continuing tendency to take 100s of photos of the same subject ( ) I'm considering purchasing Aperture (I best do it whilst I still qualify for the edu license). As I understand it, a key advantage of this software is its better RAW handling (which I shoot in) over iPhoto, insofar as it doesn't clutter up your hard drive with copies of the original NEF as you apply changes. However, what happens in Aperture when you then use Photoshop to edit the RAW file in Photoshop? Obviously with iPhoto your original RAW file is stored in the originals folder. But with Aperture when you've finished editing the file, does Photoshop import the edit as a completely new file (i.e. a JPEG) into your library, thus having two photos of the same thing? Or does it replace the original file as a RAW or JPEG file? In which case, is the original file still stored on your hard drive just in case you want to "Revert to Original"?? Apologies if I haven't explained myself very well. I have been on the Apple and Adobe website looking for the answer but I couldn't quite find it. Thanks.
