I appreciate all the content on this site, it has clearly taken a lot of time and hard work. I’ve enjoyed reading it.
People quite understandably believe that the DNGs they generate by a dedicated scanner and scanning software such as a VueScan hold undebayered RAW image data — when its actually just a TIF wrapped in a DNG.
The same result as when Photoshop allows the user to wrap a JPG or TIF in a DNG…
As you say — if someone is using a DSLR to capture their negatives — is strongly recommended to archive the (real) RAW/undebayered files.
There are few if any advantages in archiving a DNG over a TIF from a dedicated film scanner unless the scanner (could provide the undebayered data).
