Chris,
Yes indeed, SHQ is just unsquashed .jpg according to my docs.  I don't 
really know the effect of compression other than producing a smaller file 
by throwing stuff away, which seems like a bad thing and waste of all the 
capture effort.  A number of years ago I knew of a very fine photographer 
(who was unfortunately otherwise a pretty nasty person), who would archive 
all his keeper images as .jpgs at quality level 12.  That results in a file 
about half the size of a .TIFF or .PSD but still very large for a .jpg.  A 
large .jpg seems a bit like dehydrated water with some of the water stirred 
back in.  I sometimes save SHQ captures after postprocessing as .PSDs just 
because I keep thinking saving to .jpg takes the blood out of them.

Are you still working with jp2000?  If so, how's it working out?
