Common options for effects | 611
Changing effects with open panels
To experiment with an effect, you must display all required panels before choosing an effect. For example,
the Color Overlay effect combines the selected paper texture and main color to define the overlay. If the
Papers and Color panels are open when you choose the effect, you can change paper grains and colors to
create different overlays before applying the effect to your image. Any changes in the paper or color appear
in the Preview window in the ColorOverlay dialog box. You can move an effect’s dialog box around on
your screen, if necessary, for full access to other panels.
Applying effects using source luminance
With Corel Painter, you can apply some effects to an image by using the luminance values of a specified
source, which can include an external source or the luminance of the image itself. The intensity of the
effect on the image is based on the light and dark values of the source. A larger degree of change to the
light areas of the source, and a smaller degree of change is applied to dark areas. For example, when you
choose Paper as a source, the effect is applied according to the light and dark areas of the paper selected
in the Paper Libraries panel. You can also choose a pattern or external image (clone source) as a luminance
source.
The luminance source options are listed in the Using list box and they vary between effects. The luminance
options can include:
• Paper
• Image luminance
• Original luminance (pattern or clone source)
• 3D Brushstrokes
• Alpha channel or layer mask (Note: This option is available only if your document has a channel or a
layer with a layer mask.)
These options are explained in greater detail in the Help for each of the effects. The best way to see how
these options affect your images is to try them.
