make using the curves and sliders in the Gradations window are saved
with the current setup. The contrast, brightness, gamma and shadow
depth settings can also be adjusted using the Contrast tab of the Setup
window.

Using the Sliders

The sliders provide a quick and easy way to adjust the contrast,
brightness, gamma, and/or shadow depth of your images. These
adjustments affect the image, but are not reflected on the gradation graph
that appears at the bottom of the window if you click on the triangle.
The sliders behave as follows:
• Contrast: This control affects the contrast in the image. Positive values
increase contrast in the overall image by compressing the contrast in
the highlight and shadow areas. Negative values reduce contrast in the
midtones, but improve visibility at the extremes of the tonal range. This
control is easy to use, but is less precise than using the curve.
• Brightness: This control affects the brightness of all points in the
image. Positive values brighten the image, negative values darken it.
This control is easy to use, but is less precise than using the curve.
• Gamma: The gamma setting applies a predefined gradation curve.
However, unlike the standard gradation curve, the gamma setting is
strictly controlled, so it enables you to use a color management program
that is calibrated to the scanner at a given gamma setting. The default is
2.0. If you raise the gamma setting, then the image will become lighter
and more details will be visible in the dark areas. The opposite occurs if
you decrease the setting.
• Shadow depth: This setting controls a complex algorithm that affects
the level of detail visible in the shadow areas of your image. The higher
you move this slider, the more detail you will be able to see in the
shadows. However, this will also reduce contrasts in the rest of the
image. A setting of zero effectively disables this feature.
For Apply setting or Reset/Preset see at page 88.

The sliders affect all colors equally. They are not affected by the setting in
the color channel pop-up menu located above the gradation curve.
