This one not quite as clean as the JPG for me, plus the White balance is not as good in this one either. sky is a bit cleaner here. I think you meant to to state (PNG) file. I've never seen a (DNG) File. Thanks for posting both.
@digicam :Digital Negative
Adobe developed the Digital Negative (DNG) format in 2004 as an open-source alternative to the proprietary RAW formats that most camera manufacturers used.
What Adobe did was essentially level the playing field by giving everyone access to the same format for working with RAW files.
DNG is open-source, which means anyone can use it without paying licensing fees. A few manufacturers like Pentax and Leica support DNG natively. However, for everyone else, there are easy ways to convert RAW files to DNG and get all the benefits of the latter without the hassles of the former.
