For more advanced processing, Nikon offers the considerably more sophisticated Capture NX2, which is a truly professional-grade platform for in-depth raw and JPEG adjustment.

As detailed on the previous page, the Nikon D3S is a highly responsive professional DSLR camera that has great ergonomics, build quality and a fantastic feature set - but it’s the image quality department where the real news is.

This provides a very detailed view even in quite bright light that makes it easy to assess critical focus, so it is especially useful when shooting still life or macro subjects when depth of field is very restricted.
