Re: I thought PDF's could just be used to *encapsulate* regular TIFF's?
I.e., in much the same way that they can encapsulate JPEGs, etc.
It can; in fact, when you create a PDF from a scanner, encapsulation is all
that Acrobat is doing, it's the scanner software that determines the format,
which can be tiff, jpeg or some other formats that the scanner software
supports. But by default, it is almost always JPEG.

I typically scan documents to TIFF files. Then, open Acrobat
(not Acrobat Reader) and paste the document in along with any
added text, etc.
So, it was my understanding that Acrobat did NOT further process
the TIFF -- nor a JPEG, etc. Rather, just "held it in place
on the page"
?

Actually, I know of several duplex scanning systems that generate PDFs
directly. My friend owns one and he scanned a large number of Atari
documents with it.

The public library in my pop. 7,000 town has a quite capable
copier / scanner that automagically scans (or OCRs) and ftp's
to another machine, as TIFF or PDF or Word.

By default, it complains at you if you don't tell it what format to use.
