[HUG ] Re: IMG: Triptych

Hi Austin,
I know with my Nikon Scan software (and others, I imagine) there is a built in 
logic that clips a bit in from the left and right of the histogram. So though a 
TIFF file may indeed be lossless, there is software in the process that must be 
doing some interpretation. I imagine each platform (camera, scanner, etc.) has 
it's own sofware that creates a TIFF file.
With raw, you bypass all that in just get what the electronics of the platform 
is outputting (whether to your raw file or to the software/firmware creating 
the TIFF).
That's my non-technical/non-engineer's understanding.
Best,
Bob

TIFF shouldn't, it's typically a lossless format.  I always scan in TIFFs.
Scanners typically don't support "raw" file formats, TIFF is their lossless
format.  JPEG, sure.
