I don't think this is correct, RAW files are not
compressed from what I understand, they are just that RAW, the reason they are
smaller then say TIFF files is because they have not had any of the color
information applied to them, I cant remember the exact term but anyway if you
could see a raw file as it exists it would be in a gray scale with no white
balance applied to it, when you open a RAW file in whatever file
browser/converter you use it applies the information recorded and encrypted in
the file, this is what makes RAW so versatile, when you open it you can change
several things, such as white balance, exposure to a degree, and any number of
things, once this is done and you convert it to say a TIFF file it becomes
larger because the information has now been applied to the file, I hope this
makes sense.
and don't do away with those file converters that
come with your camera in favor of a third party converter such as PS' converter,
in most cases PS and others have no where near the information about the
internal workings of the camera as the manf.
