Image parameters

The Digilux 2 provides some control over the three standard image parameters of Contrast, Sharpness and Saturation. These parameters can be adjusted from the 'Picture Adjust' option on the record menu. Typically I was disappointed to find just one degree of adjustment (Low, Standard, High) for each of these parameters, manufacturers really need to provide users with a greater range of adjustment than this, it begins to look a bit like a token gesture.

Contrast

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.

Sharpness

The Digilux 2 allows you to control the internal sharpening of the image by a degree of one plus and minus it's "normal" sharpness. As you can see the Low setting removes almost all sharpening artifacts but doesn't affect detail too greatly.

Sharpness: Low Sharpness: Standard
 
Sharpness: High  

Saturation

Saturation adjustment allows you to control the strength of color in the final image.
