My company uses TIF format extensively for document archiving.  I know 
that we have several volumes of documents that, when viewed with 
Microsoft Document imaging appear correctly, but when viewed with 
IrfanView appear to be white on black instead of black on white.  
Running them through the "negative" filter in IrfanView makes them view 
correctly.  Strangely enough, going back and then viewing them with 
Microsoft's document viewer they are still correct.  It's almost like 
some TIF viewers are just incorrectly interpreting the color palette in 
Group4 TIFs.
