[Leica] OT: HELP Nikon scanner neophyte

[rgacpa at yahoo.com (Bob Adler)]

Yes LR works on .tif files, as does CS#.

You can't edit with Camera Raw if it isn't a Raw file. You can certainly do 
non-destructive edits on a .tif file (using LR or CS# layers), but my 
understanding is that a .tif file is created by software interpreting the 
sensor output (either scan or camera). A Raw file is simply the sensor 
output without any software interpretation (other than the obvious firmware 
interpreting the RGB value to give photon strengths received).

So the advantage, IMO of saving a raw file from a scan is the same as saving 
it from a camera instead of the .tif file. All manipulation is up to the 
owner, not the software.

But I'm no engineer and am probably barking up the wrong tree. Perhaps 
others would know and I would be very interested in hearing thoughts.
Best,
Bob

Doesn't LR work on tiffs too?  I know Camera Raw does.  I see no advantage 
to saving scans as DNG.  Edits made in Camera Raw are even written 
non-destructively in the tiff if I recall.

Unlike raw files from cameras, scanned files are already full RGB data, so 
they aren't raw in the same sense.
