On top of the new Nikon D4s annoucement, a new announcement came out about Nikon Capture NX-D RAW Processing Software. The software will allow you to maximize the Nikon camera and lens capabilities and create the "ultimate image quality that Nikon intended."
If you used any of the previous Nikon software applications, you may notice that this offers a number of different display formats with flexible operations just like in previous programs. You can display thumbnails above, below, to the left, or to the right of images or you can display just two or four images to compare and make easy selections of your favorite ones. On top of that, there will be a display to compare your RAW image before and after adjustments have been applied so you can get an idea of what you did. This really helps so you can take a step back to see if you overdid your edit or if you got it just right.
Up until this point, Nikon used a format for files that saved the adjustments directly to NEF and the NRW files. Now, with the adoption of a sidecar format it will save adjustments to a separate file to preserve RAW files in their original, post-capture state. Also, the sidecar format makes it easy to apply multiple adjustments across a slew of files. This makes for quick editing speeds in bulk amounts.
Based on the screenshots that Nikon has shared on their site, I think the interface looks clean. Nothing to crazy going on, which is good. Overall with a processing program, I don't think anything should be too distracting. You need to be able to focus on the image in front of you.
With this announcement, I am left here kind of scratching my head. The first thing that came to my mind was "how is this different than Lightroom and why should I choose it over Lightroom?" Still, I am sitting here with the same questions. The BETA is open for users to test and I look forward to hearing back from anyone who gives this application a try.
