  2. Merging and Splitting -- Pen • Create an open or closed shape with the pen tool. Hold Shift key for 45 degree angles. • Single clicks create corner vertices. • Dragging creates rounded vertices. • Use Pen+ tool to add vertices to a segment. • Use Pen- tool to weld over vertices on a segment. This works with any shape. • Control panel has icons for corner / curved vertices. • Cut actually removes vertices or segments.

  3. Merging, Shaping, Splitting - Pencil • Draw two segments with a hard bend using the Pencil Tool. Direct Select corner vertex. • Convert between Corner and Smooth vertex using Control Panel. • Select entire Shape, use Smooth Tool (pencil) to smooth its kinks. Try altering direction. • Path Eraser removes portions of a path.

  4. Merging and Splitting -- Brush • Draw two Brush Strokes with neighboring but unconnected endpoints. • Direct Select the neighboring endpoints. • Control Panel Connect Selected Endpoints. • Direct Select some vertices. • Control Panel Cut Path (scissors). • Note two-level pull-down-menus to load graphics libraries for stroke and fill.

  5. Pathfinder • Window -> PathFinder. • Create some overlapping filled rectangles. • Select them all & try Pathfinder Shape Modes. • Stay in Select mode, use Undo, another Shape Mode. • Pathfinders actions. • Use two overlapping rectangles with fat stroke and fill. • Pay attention to which one is in front. • Use Object -> Arrange if necessary. • Some actions convert an object to a clipping mask.

  6. Symbols • Window -> Symbol. • Use pull-down to display Symbol Libraries. • Sprayer sprays symbols into a Symbol Set on the Layer. • Other symbol transforms manipulate symbols, double click icon to modify parameters. • Alt / Option reverses effect. • Alt / Option on sprayer deletes symbol of the type selected from the symbol library.

  7. Example 1: A Visual Migraine • Retrieve DaleParsonDual.zip from Outbox. • Open CounterStillLIFEFINAL.psd. • PhotoShop to adjust initial image area. • Radial blur and Filter -> Brush Accent Edges. • Base photo placed into Illustrator to add Geometric objects and related effects. • Export shapes to PhotoShop format. • Import into composite image for blurring, effects and blending mode for final image.

  8. Example 2 • AquariumDual.psd from Albuquerque Aquarium, photo by Linda Parson. • PhotoShop to adjust initial image lighting and reduce reflections. • Place into Illustrator to add Type and Type effects. • Export to PhotoShop for final color curves touchup in AquariumbabyType.psd..
