Digital BW, The Print

Strictly speaking Tiff is a proprietary format managed by Adobe, 
originally designed by Aldus. It is not an international standard. Its 
also not in any realistic sense a single format - there are many 
different Tiff formats (T stands for tagged, and the tag defines what 
the file actually contains). I wouldn't bet on all Adobe layered  TIFF 
files being readable by all image processing applications - what does 
Lightroom do with them?  I wouldn't even bet on Photoshop being able to 
read use all data contained in all current Tiff file formats. Likewise 
DNG is an Adobe format, not an international standard, one reason not 
everyone adopts it.
