RAW is the data before it is been processed into a reconisable image. That is why most RAW files have a JPEG embedded within.

Well...sure...and if you're seeing an image at all, it isn't a JPG, as such - It's the JPG data converted by the ubiquitous JPG processor into a bitmap so you can view it on the display.

The point I was trying to make is that some programs (Picasa, and of course ACR and Silkypix) and not others (Irfanview) can ignore the embedded JPG and create a visible image directly from the RAW component of the RW2. (and I presented a very simple way to distinguish the two.)

That's different to the impression you gave in your original post.

Do you have a better way to express that process?

You mean, now that you have expressed it? The answer is No.
