Nikon D3X In-depth Review
Image parameters (contd.)
Adjusting the tone alters the shape of the 'S curve' used to map the linear image data captured by the sensor into the correct gamma. A lower contrast setting maintains more of the original data's dynamic range but leads to a flatter looking image. A higher contrast setting stretches the grayscale (dark to light) of the image and could lead to clipping of both shadow detail and highlights. Nikon is providing a fairly wide range of adjustment (seven levels in total) but the latitude of change is smaller than we would have expected, we would expect -3 to provide even flatter and +3 even more contrasty images.
The Brightness adjustment makes a subtle linear brightness adjustment to the image, essentially shifting the 'black point' slightly from the default. It's latitude of adjustment of -1 to +1 is very small though and somewhat limits the usefulness of this parameter.
Saturation (color) adjustment
Saturation adjustment allows you to control the strength of color in the final image. There is a good range of seven adjustment levels in total, but we probably would have liked even less saturation at the -3 end of the scale.
Hue (color) adjustment
The hue adjustment setting allows you to make some subtle changes to the hue output of the image, it is useful for compensation of hue shifts caused by certain artificial light, a negative setting makes color appear more blue-ish, a positive setting makes color appear more yellow-ish.
