Canon EOS 350D / Digital Rebel XT/ Kiss n Digital Review
Custom Parameter Sets
The EOS 350D has the same level of adjustment as the EOS 20D; two preset sets and up to three user defined sets. You get five levels of adjustment (plus or minus two levels) for contrast, saturation, color tone and sharpness. Some of the adjustments could have benefited from a wider latitude of adjustment and perhaps even more steps.
Image parameter adjustments
- Contrast: -2, -1, 0, +1, +2
- Saturation: -2, -1, 0, +1, +2
- Color Tone: -2, -1, 0, +1, +2
- Sharpness: -2, -1, 0, +1, +2
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.
Color saturation adjustment
Saturation adjustment allows you to control the strength of color in the final image. The latitude of adjustment in this case is probably about right without getting into really de-saturated images or over saturated color which may channel clip.
Color tone adjustment
Color tone subtly adjusts the hue of the image, a negative setting makes color appear more reddish, a positive setting makes color appear more yellowish.
