    Why does DNG Converter insist on lossy conversion?

    Kawika808 Level 1

      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:

      Original RW2 image, with histogram:

      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.
