FZ200 - Great Grey Owl, 11 stacked RAW images, enlarged to 8000 pixels wide

What amazes me is how much noise can enter the picture even when it's taken in RAW (or RW2).  (As demonstrated by how much noise is covered up by stacking).   I would have expected these kinds of results from JPG images but not from RAW.

And that leads me to the next question: the FZ150 also saves RAW files as RW2... so why is it (other than possible optical considerations...which must be very small) that makes an upgraded version of Silkypix or other software necessary when "upgrading" from 150 to FZ200?

Rudy, fantastic shots to use for your processing "experiments"!
