虽然像魔术橡皮擦这样的工具有时可以删除你的背景，但事实是，如果你有复杂背景的图像需要删除，你就必须用橡皮擦把你的手弄脏。虽然这可能很费时，但你可以通过一点Photoshop的魔法节省自己很多时间。我们来看看。

右键单击图层调色板中的背景图层，然后选择“背景图层…”它将自动重命名为图层0。只需按OK。

图层调色板应该只有一个图层，即新解锁的“图层0”

Press to select the Lasso Tool. Check your opti*** on your Control Palette near the top of your Photoshop screen. Make sure that yours looks like this screenshot. Most importantly, be certain that “Anti-Alias” is turned off.

用套索在你的图像周围画一个粗略的选择。别担心精确，我们稍后会更精确地删掉它。

When your selection is done, press to move your rough selection to a new layer with “Layer Via Cut.” You can safely delete “Layer 0” and work only in your new layer.

Press to bring up the eraser tool, or find it in your Toolbox.

再次访问控制面板，将“模式”设置为“铅笔”，这样可以确保橡皮擦有硬边。

使用橡皮擦鼠标移动并删除不需要的部分。靠近你的图像，但在切入时要小心。

Keep in mind you can always undo with a swift to undo or step back through your history(It’s like multiple levels of undo, in case you’re not familiar).

你不需要在这一点上删除每一个位。一旦你在你的图像周围建立了一个连续的间隙，我们就可以开始删除你不再需要的多余的东西。

在这里它变得有点先进。你可以简单地用你的橡皮擦删除图像的剩余部分，但我不喜欢花更多的时间在日常工作上。

Hold and click your “Layer 1.” This will load a selection around your entire roughly cut out image.

Open the Channels Palette and click the icon to create a new Alpha Channel.

Select this Alpha Channel (likely “Alpha 1”) by clicking it. It also lists a shortcut to it. A simple in an RGB file will jump right to it.

进入编辑>填充并将填充对话框设置为“使用：白色”，就像我在这里显示的那样，只需按OK。

Your Alpha chanel should fill with white in the shape of your roughly cut out image. Press to Deselect.

单击并按住渐变工具以打开上下文菜单。拿起油漆桶工具。确保你的“前景色”是黑色的。

只需点击你不想用黑色填充的区域。如果你的任何多余的区域接触到你的图像，它也会填满，所以要小心。

and Click on your Alpha 1 Channel to load the new selection you have just made.

Press to return to your RGB. The Tilde key is located to the left of your on a USA keyboard.

Return to your Layers Palette. Press to move your selected image to a new layer. You can safely delete your old layer or simply choose to hide it.

你的图像现在正是从你的背景中剪下来的。

I usually click the to add a Color Fill style Adjustment Layer at the bottom of my Layers. This helps me check my work for halos and mistakes.
