I see that the newest DNG 11 version includes support for the Nikon P1000 raw file format. In the description , the file extension for P1000 is listed as NEF, but the camera actually creates NRW files. I downloaded and installed DNG 11 on Windows10 64-bit. In looking at the folder containing the NRW files, it says that it doesn't contain any files for conversion. I can see these NRW raw images as thumbnails in windows explorer and open them with Nikon software.
Additionally, DNG 11 won't recognize NEF files created by a Nikon D7000, even though I can process them with Photoshop CS5 with camera raw installed. I thought that DNG was backward compatible, and indeed the Nikon D7000 is listed as a compatible camera. I've uninstalled DNG 11 and reinstalled, but there is no change in behavior. I'm at a loss to explain why this version of DNG doesn't seem to work at all.
