I have a bunch of NEF files taken with a Nikon Coolpix 5400. This camera's NEF format is not supported by Aperture or Mac OS X. Just as a wild experiment, I tried editing the file /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/Raw.plist; and copying the profile for the Canon S60 (the most similar camera I could find to the 5400) to a new Nikon CP5400 section. This actually sort of worked - now Aperture can see my NEFs, but they have a yellow/green tinge. This is obviously not acceptable, so I tried the Adobe DNG Converter to convert the NEFs to DNGs. But I have the same problem with the DNGs - Aperture/OS X can't read them. So what's the point of the DNG format if a RAW file converted to it still can't be read without explicit support for that camera? And does anyone have any ideas when/if Apple might ever support the Nikon Coolpix 5000/5400?
