Nikon Picture Control

 

NPC is an utility which is now part of View NX (1.5.2.), and allows to  modify and apply a set of image styles to NEF/Raw pictures.

It can be used for editing the profiles included in cameras with Picture control (D3/700/300(s)/90/5000/3000).

See Nikons answer on how to modify Picture control.

Some interesting information can be found here or here

What I think is interesting is the ability offered by View NX utility to correct color fringes, to apply D-lighting or D2x styles

D2XMODE1
This optional Picture Control simulates color reproduction at a D2X/D2XS Color mode setting of I.
Skin tones and gradations are reproduced naturally with rich reproduction of tones.

D2XMODE2
This optional Picture Control simulates color reproduction at a D2X/D2XS Color mode setting of II.
This optional Picture Control is suited to images that will be extensively processed or retouched.

D2XMODE3
This optional Picture Control simulates color reproduction at a D2X/D2XS Color mode setting of III.
Choose for nature or landscape shots. Greens and blues are vividly reproduced.

*To achieve a level of brightness similar to that of images captured with the D2X/D2XS, set Picture Control Brightness to -1. Color reproduction precisely the same as that achieved with D2X/D2XS Color mode settings I, II, and III is not guaranteed with the three D2XMODE1, D2XMODE2, and D2XMODE3 optional Picture Controls.

*D2XMODE1-3 optional Picture Controls must be registered with the camera before custom Picture Controls, based on D2XMODE1-3, can be created using Capture NX or ViewNX and registered with the camera.

 

A whole set of presets simulating classic film rendition (Velvia, Sensia, Kodachrome, etc.) can be found here.
