第一种方法：钢笔工具
Select the Pen Tool from the Tools on the left. It’s easier if you zoom in to your image and start to create a new work path by plotting Anchor points along the outline of your subject.
Once you have closed the workpath, go to Paths tab and you will see your newly created workpath there. Ctrl-click on the workpath layer to load selection. Select > Inverse to select the area outside the subject. Press Delete. |

第2种方法：抽出滤镜
Open up your image and go to Filter > Extract. A new interface will appear. Select the Edge Highlighter tool with an appropriate size, draw along the outline of your subject. It does not have to be very accurate.
Get the Fill tool to fill within the highlighted outline you drew earlier. Click on Preview button. Hit OK if you are satisfied else redo highlighting th edges. |

第三种方法：图层蒙版
Select the layer of the subject and click on Add Layer Mask. You will see a white box appear on the layer tab. Select Brush tool of an appropriate size and color #000000, start painting the areas outside of the subject. Things to note are, #000000 is to hide and #FFFFFF is to reveal details.
This method is very forgiving by toggling between these two colors. |
