- the left bracket "[" selects the next smallest brush
- the right bracket "]" selects the next largest brush
Note: it's better to make the selection slightly smaller than the object
9. When done, press "Q" to exit Quick Mask and return to "Selection" (marching ants).
10. Add layer mask of selection: [click+ add Layer mask icon]

Lesson 4: Practice "The Method" using selections, layers and layer mask techniques
Objective: To learn how to create layer masks. To see how these masks, along with a portion of the image, when isolated on its own layer allow total control and the ability to reedit how much of the image is seen. Practice "The Method" to enhance the digital image.
Select and mask various face parts:
1. Open "Selection.psd" file.
2. Make the "Background" Layer active
3. With the "Rectangle" selection tool draw a bounding box slightly larger than face part...

{see "Face Parts List" below}

4. Create a new layer [Alt+Ctrl+J] and name it... [name = selected face part]
5. Make only new layer active and visible [Alt+click layer-eye]
6. Begin the selection process:
 

a) Zoom in to object... [draw bounding box with zoom tool]
b)
Choose the appropriate selection tool and create a selection of desired area
... [if necessary, use "Quick Mask" to refine selection]
c) When done selecting, add a layer mask: [click+ add Layer mask icon]

7. Double-click "Hand" selection tool to show entire image
{ --- repeat from Step 2 and select next "face part" from "Face Parts" }
- When done selecting all face parts continue -
Compose "Face", Flatten, and Save:
  1. Make ALL layers visible
2. Move layers into place and prioritize to create face
... [reference example in upper right corner]
3. Save As "Melonhead.PSD" [editable file]
