From the developer:
Capture NX-D photo processing software lets you realize the full potential of your Nikon digital camera and lens, producing images with the unsurpassable quality envisioned by our designers. It offers features specifically designed for post-processing of RAW images and provides them in an intuitive, easy-to-use form.
