Soware Reference - FlexColor 4.0 for Flextight
small triangle beneath the Shadow depth slider. All of the settings you
make using the curves and sliders in the Gradations window are saved
with the current setup. e contrast, brightness, gamma and shadow
depth settings can also be adjusted using the Contrast tab of the Setup
window.
Using the Sliders
e sliders provide a quick and easy way to adjust the contrast,
brightness, gamma, and/or shadow depth of your images. ese
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.
e sliders behave as follows:
• Contrast: is 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. is
control is easy to use, but is less precise than using the curve.
• Brightness: is control affects the brightness of all points in the
image. Positive values brighten the image, negative values darken it.
is control is easy to use, but is less precise than using the curve.
• Gamma: e 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. e 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. e opposite occurs if
you decrease the setting.
• Shadow depth: is setting controls a complex algorithm that affects
the level of detail visible in the shadow areas of your image. e 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.
