Or use Photoshop 7, 6, 5.5, 5, etc.  I seriously doubt that there are 
any advancements in newer versions of Photoshop which make 
counterfitting significantly easier.  Scanning is scanning, and given 
that what you're trying to do is reproduce an existing image, not create 
a new one, the editing features found in new versions of Photoshop will 
provide very little advantage in this regard aside maybe from a little 
clean up of dirt on the glass of the scanner.

The point is, they don't really raise the bar to counterfitting, all 
they do is raise the bar to legitimate use.  Besides, there's always 
Gimp and open source software.  Building in such restrictions to that 
software, given that the code source is available means that any serious 
counterfitter will recompile with out the protections.  There'll 
therefore always be photo editing suites available which don't possess 
these limitations, and so there'll always be a way around it.  It's the 
wrong approach to preventing counterfitting, it's kludgey and won't ever 
work well. 

I guess though what it *will* do is prevent teenagers from printing out 
$5 bills and tossing them in the coin machine at the arcade, or any 
other electronic eye.  This is petty theft though, and it hardly seems 
fair to restrict legitimate consumers, costing them ultimately hundreds 
of hours to lost performance or costing them the fair use of money 
images to save $5 here and there.

It's the same problem as DRM enabled music.  It'll always be defeatable, 
and given that in that case there's the "analog hole" problem, will not 
ever stop someone serious about committing the crime, thus all it does 
is inconvenience or prohibit fair use.
