Finally, Nikon (previous developer Nik Software was bought by Google in 2012) has released a free RAW (NEF) editing software! This is brilliant! I have yet to download it to try, but the page shown looks good.

Capture NX-D is a free software application that will replace the current Capture NX 2 application
