Image parameters (contd.)
Sharpness
The sharpness setting of zero literally means 'apply no sharpening at all', hence this is the image as captured (soft because of the anti-alias filter). The default setting for Standard Picture Style is two and three for Landscape.

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. The EOS 400D provides a wide range of adjustment with nine steps from -4 to +4.
