Capture NX-D is software for processing and adjusting RAW images, (with the NEF or NRW file extension), captured with Nikon digital SLR cameras. It is now available for download as free beta version.
In addition to RAW images, the application can also be used to adjust JPEG and TIFF files.
Nikon will continue to update and provide support for the current Capture NX 2 application while the beta version of Capture NX-D is available. However, once the official version of Capture NX-D is released, they will no longer support Capture NX 2.
