Outline for week 12
Merging, Splitting, Pathfinder, Symbols

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.
