I don't see it in CS2. Remember, too, that RAW is a generic term. For
Nikon you'd have to save the file as a (non-demosaiced) NEF file. For
Pentax it would be a PEF file.
Ah, okay.
In Photoshop 7, 16-bit files have three save options: PSD, TIFF,
RAW. I've never bothered with that RAW since TIFF was always
industry standard.
In Photoshop CS2, it's called "Photoshop RAW". This is not the same
thing as PEF or DNG, it's essentially a row x column array of RGB
pixel values to the dimension you set in the Image Size dialog.
Demosaicing and gamma correction are non-invertible functions: you
cannot retrieve all the data for a camera RAW format data file once
these functions have been performed.
