I use DNG Converter to convert RW2 files to DNG so I can work on them in various PP programs.
No matter whether or not I have the "lossy" box checked, DNG Converter insists on doing a lossy conversion.
How can I stop this?
Sample images:

DNG image - note loss shown on histogram. There is also posterized banding, although in the small image allowed on this site it is very hard to see.
