Using the Gradations Color Picker
The
Gradations Color Picker
in the lower left corner of the
Gradations
window enables you to place a gravity point on
the curve at the brightness of a point that you select in the
preview. Click on the eyedropper icon to activate the
gradations color picker, then click on a point in the preview
to place the gravity point. See the next section for more
information about using the curve.
Using the Curve
The gradation curve is a plot of input brightness (on the horizontal-axis)
versus output brightness (on the vertical-axis). It provides extremely
detailed control over brightness and contrast in your final image, and
even provides individual control over each color channel. You can hide or
show the curve by clicking on the small triangle beneath the
Shadow
depth
slider.
To adjust the curve, click and drag on the graph. Each time you click on a
new point, you will create a gravity point, which will pull the curve
toward itself. This system makes sure that the curve is always smooth.
The preview image will update to reflect your changes.
Here are some guidelines to help you make adjustments to the gradation
curve:
•
To add a gravity point to the curve, click anywhere on the graph or use
the Gradations Color Picker, as described in the previous section.
•
To remove a gravity point from the curve, click on the point and then
press the backspace button on your keyboard.
