It has been a long time since I read the tech articles on the dng
format. However, when I did (back when Adobe first announced it) I
seem to recall that they referred to the compression as "non-lossy."
I don't understand enough about the 1's and 0's to make a claim one
way or the other. But I've read about other compression schemes which
also claim non-lossy compression.
