Which format adobe RGB (1998) or sRGB IEC61966-2.1 is best for filing? Raw or Jpeg. When I load photoes from my nikon D700 or leica M8, to Aperture I get these 2 formats, do I have to keep them both or can I delite one of the versions in my library to save space?
Are you shooting RAW+JPEG? Because otherwise what you're asking doesn't really make sense... you shouldn't have a different file for each color space.
