Lesson 3: Refining Selection Using Quick Mask
Objective: Learn how to use Photoshop's Quick Mask mode. Use keyboard shortcuts to enter and exit Quick Mask mode, toggle between fore and background colors and change brush size.
Quick Mask keyboard shortcuts:
  - "black" blocks (adds to the mask) and [white] clears (removes the mask)
- "X" on the keyboard toggles between black and white
- " [ " the left bracket selects the next smallest brush
- " ] " the right bracket selects the next largest brush
Select the kiwi and refine with Quick Mask:
1. Open "Selection.tif" file.
2. Make "Background" active
3. Use the "Rectangle Marquee" to select an area slightly larger than the kiwi
4. Create a new layer [Command+J] containing the kiwi
5. Make only this new layer active and visible [Option+click eye]
6. Draw a bounding box with the "Zoom" tool around the kiwi
7. With the "Magic Wand" set at a tolerance of 48, click near the edge of the kiwi
8. Press "Q" to enter Quick Mask and remove the red mask from the center of the kiwi:
  - Use the "Paint Brush" tool, to "add" or "subtract" from the mask:
 
- [black] blocks (adds to the mask) and [white] clears (removes the mask)
- "X" on the keyboard toggles between black and white
- 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
