Ricoh GRD IV first steps

I actually have not felt the need to shoot raw since i got my GRD4. I did try but it appears that either Aperture or my use of aperture does not give me as good a result as the cameras jpegs.

Aperture 3 always seemed to get it right with my 5D and pany G3. But alas no cigar with the Ricoh DNG files.
