3. Lasso & pen
in front of us talking about are for irregular, and pen and lasso the requirements are clear edge shape as regular as possible. 
3.1 We first try to use the magnetic lasso it, the mouse walking along the edge of the red leaves, magnetic lasso will automatically identify the constituency. But we walked around will find the lasso is not enough accurate identification, will be some errors.
3.2 We fine-tune it, and replaced with the lasso selection tool to get neat. Then Ctrl + Shift + I selected reverse, so the choice is yellow leaves, Delete to see results. 
3.3 lasso may think the image too demanding, but also a little bad control, then we try to pen it. Use the pen is left mouse button, draw up a broken line, press the mouse is drawn curve, try this myself, oh. Remember, the less smooth the curve plot points.
3.4 walk around back to the original starting point, closed path. 
3.5 mouse on the path inside the pen, right-click the mouse to make selections. 
3.6 Delete it, perfect!
