Image parameters (contd.)

Tone (contrast) adjustment

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. Although the range from lowest to highest contrast isn't immense, it's slightly better than the D40X, and is probably enough for the typical user to fine tune the output without going completely over the top.

Color saturation adjustment

Saturation adjustment allows you to control the strength of color in the final image. As Phil commented in his D40 and D40X reviews the range of adjustment is so small that it's almost pointless providing this option, we need at least two levels of adjustment either side of 'normal' with a wider latitude of difference between each step than this.

Color hue 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 yellowish. The D60 provides a range of -9° to +9° hue shift.
