Lesson 1a: Basic Layer functions:
Keystrokes are for Windows... for lesson with Macintosh keystrokes Click here
Objective:
Create new; make active; name and prioritize layers.

File(s) Needed: PSPwindow.TIF
1. Open "PSPwindow.TIF" file and optimize using Menu:>Image>Adjust>Levels
2. Create a rectangle selection box over the left window
3. Make a new layer and name it "red": Menu:>Layer>New: "red"
4. Change foreground color to RED [R=255 G=0 B=0] and fill selection: Menu:>Edit>Fill:Foreground color

  < Use the Menu: >Select>Transform Selection to adjust and position the circle
6. Make a new layer: [Click "New layer" Icon] at bottom of Layers palette
7. Change foreground color to GREEN [R=0 G=255 B=0] and fill circle selection [Alt+delete]
8. Create a triangle selection over the right window using the Polygonal Lasso tool
9. Make and name new layer "blue": [Alt+"New layer" Icon]
10. Change foreground color to BLUE [R=0 G=0 B=255] and fill triangle selection [Alt+delete]
11. Double click "green" circle layer and name it "green"
12. Click the "Background" layer to make it active… Notice it is highlighted and has a paintbrush icon
13. Rearrange the layer's priority from top to bottom so the order is: "red"/"green"/"blue"
  a) Click and hold mouse on the "red" layer then drag it to the top of the stack

Keystrokes are for Windows
Objective:
Learn various ways to "undo"; History Palette & Snapshots; link and move Layers.

Lesson 2: More Layer functions
Keystrokes are for Windows
Objective:
Create 3 new layers containing "windows" in the shape of "red", "green" and "blue" layers. Learn how to "select" layer shape; create a "New Layer via Copy"; adjust Layer Opacity and turn layer on and off.
1. If not opened, open "PSPwindow.psd" file
2. Create new layer containing a portion of the "Background" similar to the shape of the "red" layer
 

a) Make the "Background" layer Active
b) Create a selection the same shape as the "red" layer: [Ctrl+Click] "red" layer
c) Create a new layer with a portion of the "Background" and name "rectangle": Menu: >Layer>New>Layer Via Copy or [Ctrl+Alt+J]

{Repeat with "green" and "blue" layers and name layers "circle" and "triangle" respectively}

3. Shut off "Background" layer by clicking on the layer "eye" icon.
4. Move shaped photo layers under same graphic shapes:

- "rectangle" under "red" layer
- "circle" under "green" layer
- "triangle" under "blue" layer
5. Change opacity of the "red" layer to make it transparent:
  a) Make the "red" layer Active
b) Change the "Opacity" setting at the top of the Layers palette from "100%" to "50%"

Keystrokes are for Windows
Objective: Learn techniques to link; move link; duplicate; delete and merge link layers.

File(s) Needed: CONTINUING from Lesson2...
1. Link graphic layers ("red"; "green"; "blue") with shaped photo layers:
  - Link layers:

"red" with "rectangle"
"green" with "circle"
"blue" with "triangle"

2. Make the "Background" layer visible and in 3 moves, make each layer pair active then move them so there are 6 windows showing:
3. Show "History Palette" revert to previous state by and clicking on the "Lesson2" snapshot
  {notice the layers revert back to their position but the visible state of the layer does not}
4. Show "Layers Palette" and Duplicate layer:
