Apparently they are just not explicitly supporting it in their latest 
software. Agreed, it doesn't matter much at this time, and I imagine 
that Adobe CR will support it for a while, but I should cause 
everyone who uses digital to pause.

TIFF apparently is a standard that Adobe owns. They haven't said boo 
about licensing/protecting it, but they could, I suppose. On the 
other hand, they're one of the proponents of open standards. TIFF 
unfortunately is too large. For the 20D, it gives approximately 48mb 
files which is a killer, and it still doesn't have all the info in it 
that RAW does.

I think jpeg is generally safe right now, even though there are 
licensing issues. It's too pervasive to go quietly. JPEG 2000 is an 
open standard, I believe, and it's 16-bit capable, so it's a better 
choice. Only it's very compute intensive, so you really need hardware 
acceleration for it at present. I'd have to buy another computer just 
to do batch processing of RAW into JPEG 2000, and have it running 
constantly. :-)

There's no easy solution. For now, I think I'll shoot everything in 
RAW plus larg/fine jpegs in the camera, and just buy some more CF 
cards. Might not be a bad backup strategy anyway. Then I make a copy 
of all the stuff on another drive, and an off site drive gets the 
batch DNG conversions every once in a while.

I hope that all this effort is worth it, 'cuz I don't know who might 
be interested in my photos when I'm gone! 8-)

The problem is that there are a couple of photos, especially of 
family, that will be of interest in 100 years, but I don't know which 
ones....
