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. Personally I would liked to have more latitude of adjustment for this parameter. (Picture mode Natural used for these samples).
Color saturation adjustment
Saturation adjustment allows you to control the strength of color in the final image. As you can see from the crops below the latitude of adjustment is quite strong. If you prefer your color a little stronger out of the camera the +1 setting works well without over-saturating. Each level of adjustment equates to approximately a 5% saturation change (hence +2 = +10%). (Picture mode Natural used for these samples).
We used the E-330's "Natural" picture mode for these samples so treat the 'Default' as slightly lower sharpening than you would get in Vivid mode (which appears to be a step higher). If you prefer your images a little sharper out of the camera you can always use a +1 setting (although be aware of which picture mode you're in). As with previous E-xx0 series cameras increasing sharpness also increases the visibility of jagged artifacts around highlights.
