RAW isn't that kind of "format"
RAW itself isn't actually a format in the way that you're implying. RAW is an umbrella term used to describe each individual camera manufacturer's proprietary uncompressed image format; RAW just lumps them all into one as sort of the antithesis of JPG because they're all raw, uncompressed data. Canon's RAW files are *.CR2 in the newest cameras and *.CRW in some of the older ones. I believe Nikon uses *.NEF, and still other manufacturers have other formats. These are not interchangeable formats like *.JPG, *.TIF, etc.
Now if Adobe's new *.DNG (Digital Negative) format ever becomes widely accepted by camera manufacturers, then this may all be moot because then, a RAW file will be the same RAW file no matter which camera you use. But until that happens, if ever, image manipulation and management will unfortunately be more complicated than it has to be.
Somebody else may be able to explain it better, but hopefully this helps you.
reykjavik said:Maybe there is something I dont understand about digital phgotography, but if RAW is a mere file format, then why does iPhoto only take RAW from specific cameras? wouldn't that technically be the same as only importing jpg's from only specific cameras?? RAw is RAW is RAW, why should it matter what camera youre using??? (or am I totally wrong here?)
