Each camera manufacturer has its own image formats and this is the case with Nikon that uses NEF and RAW formats. Nikon Capture NX has been designed to work with these formats.
Nikon Capture NX allows you to enhance photos that have NEF, JPEG, TIFF and RAW formats. It includes tools for setting curve levels, contrast and brightness, colour balance, saturation and much more. To save time, it is possible to open several images simultaneously so as to make parallel process adjustments of several details.
