Note: You do not need to switch colors when you paint in the alpha channel, even if you paint with gray. The changes to
the opacity of the painted area are determined by the values shown for Opacity and Feather under Brush Settings in the
Effect Controls panel, not by the color of paint.
L. Under Original Alpha Only
affect the original image alpha channel, only areas outside of it. Painting adds areas of opacity; erasing restores trans-
parency to painted areas only.
Note: The difference between using Under Original and Under Original Alpha Only is that in the latter, strokes affect
only the alpha channel; RGB is unchanged.

To select Vector Paint Preference options (Pro only)

Use the Vector Paint Preferences dialog box to customize the way you view your work in Vector Paint. Unlike most
other effects, the options you select as Vector Paint preferences apply to all your Vector Paint work, both on the
current layer and on other layers. Your current preferences are also used for subsequent sessions of Vector Paint.
Select Vector Paint in the Effect Controls panel and open the Vector Paint Preferences dialog box in any of the
1
following ways:
Click the menu button
Right-click (Windows) or Control-click (Mac OS) anywhere in the Composition panel, and choose Options.
In the Effect Controls panel, click the word Options next to the name Vector Paint.

Choose the appropriate options.
Note: Better Preview While Drawing is temporarily disabled in low-memory situations, and Draft quality is used
instead. Also, if your preview doesn't drawing correctly, you may have an incompatible graphics card.

Perspective effects

3D Glasses

The 3D Glasses effect creates a single 3D image by combining a left and right 3D view. You can use images from 3D
programs or stereoscopic cameras as sources for each view. The method you use to create the combined images
dictates how you view them. For example, you can use 3D Glasses to create an anaglyphic image, which is an image
containing two slightly different perspectives of the same subject that are tinted contrasting colors and superimposed
on each other. To create an anaglyphic image, first combine views and tint each one a different color. Then, use 3D
glasses that have either red and green lenses or red and blue lenses to view the resulting image stereoscopically.
This effect works with 8-bpc color.
Original (left), and with effect applied (right)
The original image appears within its alpha channel in working view. Strokes do not
in the Vector Paint toolbar in the Composition panel, and choose Options.
