Hi Don it puzzled me too until I realised that most of my stuff comes out of Aperture and I've been exporting jpegs for editing in Photoshop, rather than editing within Aperture itself. So I tried importing direct off a card Via Capture NX2 and used an NEF file in Photoshop and Lightroom. I'm still trying to sort it out because on each occasion I ended up with PSD or TIFF - so I'm pouring through Scott Kelby looking for an answer. I have to say however I'm finding the JPEG route perfectly acceptable so I'm also puzzled by Damiens statement which I confess I just copied without reading too closely.
