I enjoy RAW files and feel I understand most of their benefits, but what I don't understand is, do they have a DPI, just like other raster-based image formats do? If so, does anyone know what the DPI is on the RAW file of a 5D Mark III? It seems like some cameras have high DPI / small dimensions, while others have low DPI / large dimensions. I could be wrong. I probably am. What I'm getting at, is I'm trying to figure out what DPI to specify in Aperture for my external editor DPI. If the RAW file is 72, I don't want to leave set it to 300 and unnecessarily bloat the file when I'm roundtripping it while editing. Thanks.
