Hello, I read in the latest issue of Macworld that OSX has a built-in capability to read RAW files. That Preview can show RAW files and iPhoto 6 can show files and allow to work on them with the retouching tools. Well, that is impossible on my iMac G5. Neither Preview or iPhoto 6 can recognize my Nikon D50's RAW files that have the suffix NEF which I know is the Nikon proprietary RAW format. Someone has a clue? Thanks Germain iMac G5 / 1.8 mhz / 768 RAM Tiger 10.4.2 français
