Image parameters contd

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. There's a good range and plenty of fine adjustment available on the K2000.

Color saturation adjustment

Saturation adjustment allows you to control the strength of color in the final image. Using the default 'Natural' image tone the chances are that color saturation is strong enough to deliver pleasing images while avoiding clipping of any particular color channel when taking shots of bright colors. That said the 'Bright' image tone can indeed cause some clipping, especially with strong reds. Hence you may wish to apply some negative saturation adjustment in this case. Good to see a wide latitude of adjustment with plenty of steps.

Color Hue adjustment

Like its two immediate forebears, the K2000 offers Hue adjustment. In the colour modes it offers a very subtle shift of the hue from cooler (minus numbers) to warmer (plus numbers). In monochrome mode it controls the tint applied to the mono images, from blue to sepia. Not something you'll use that often, but a nice addition to an already extensive set of tonal controls.
