摄影很难。不需要的物体、分散注意力的元素和不完美的背景通常会破坏原本出色的构图。幸运的是，Adobe Photoshop和Lightroom等照片编辑软件包含用于轻松编辑图像的强大工具，可(powerful tools for easy image edits)让您轻松删除这些元素。
在本文中，我们将介绍如何在Photoshop中删除背景、不需要的对象等。
在Photoshop中删除背景(Backgrounds)的3种方法(Ways)
根据主题的复杂性，使用Photoshop去除背景相对容易。在本节中，我们将介绍可用于在 Photoshop
中遮盖和隔离主题的各种工具。(mask and isolate your subjects)
1.删除背景工具
删除背景的最简单方法是使用 Photoshop 的内置删除工具。这种方法适用于清晰的主题，但如果没有清晰的边缘，可能会遇到困难。
- 在 Photoshop 中打开您的图像。
- 按Ctrl + J复制背景层。
- 导航到“快速操作(Quick Actions)”面板并选择“删除背景(Remove Background)”按钮。要找到它，请在“属性(Properties)”面板
中向下滚动。
2.使用背景橡皮擦
- 打开你的图像。
- 单击(Click)背景橡皮擦(Background Eraser Tool)工具。它将在橡皮擦(Eraser)菜单中，因此右键单击橡皮擦工具以访问它。
- 在限制(Limits)下拉菜单中，选择查找边(Find Edges)。
- 单击(Click)并沿主题的边缘拖动。慢慢来，因为该工具并不完美，您可能需要使用硬度(Hardness)和公差(Tolerance)设置来完善它。擦除主题周围的背景后，您可以轻松删除其余的背景。
3. 使用选择工具
Photoshop有多种选择工具，可让您微调主题选择并将它们与背景隔离开来。这些包括：
- 魔杖(Magic Wand)工具。如果您的主题明确定义，魔棒工具(Magic Wand)将尝试通过单击选择它。然后，您可以使用套索(Lasso)或画笔(Brush)工具细化选择。
- 对象选择(Object Selection)工具。对象选择(Object Selection)工具类似于魔术棒(Magic Wand)，但是，您在主题周围拖动一个矩形框，Photoshop将尝试选择它。然后，您可以细化选择。
- 快速选择(Quick Selection)工具。快速选择(Quick Selection)工具可让您在选择中进行绘画，就像使用画笔工具(Brush)一样。然后，您可以在之后细化选择。
- 套索(Lasso)工具。套索(Lasso)工具使您可以通过添加或删除选择来微调您的选择。单击时按住Alt（或Mac上的Option）将删除选择，而按住Shift将添加到它。要使用套索(Lasso)工具，您需要在要添加或删除的区域周围创建一个圆圈。这类似于钢笔(Pen)工具，但给您更多的控制。
- 选择主题(Select Subject)工具。Photoshop有一个您可以使用的自动主题选择工具。要访问它，请单击选择(Select)菜单并单击主题(Subject)。
选择主题后，您可以使用“选择(Select)和蒙版”(Mask)工作区进一步细化您的选择。为此，请单击选择(Select)并遮罩(Mask)。
您可以使用多种工具来完善您的选择：
- 套索和画笔工具(Brush tools)。要添加到您的选择，请确保选择添加到选择按钮。要删除区域，请单击从选择中减去按钮。
- 细化边缘(Refine Edges)和细化头发(Refine Hair)。单击(Click)“优化边缘”(Refine Edges)以微调任何困难区域。您还可以选择“优化头发(Refine Hair)”以让Photoshop自动优化头发选择。
- 使用全局调整(Use Global Adjustments)。如果选择的边缘看起来不自然，在Global Refinements下，您可以更改平滑度(Smoothness)和对比度(Contrast)滑块，直到选择看起来更好。
最后，在输出设置(Output Settings)中选择图层蒙版(Layer Mask)，然后单击确定。您的主题现在将位于图层面板中的新图层中，这意味着您可以根据需要删除背景图层。
注意：或者，一旦您做出选择，您可以创建反向选择（通过按Ctrl + I），以便您选择背景。然后你可以简单地点击删除(Delete)来删除它。
如何删除不需要的对象
有几种方法可以在Photoshop中删除不需要的对象。要裁剪出轮廓清晰的大型物体，例如人和动物，最好的方法是使用选择工具进行选择。
但是，一旦对象被移除，您将在其位置留下透明背景(transparent background)。您可以使用Content-Aware Fill工具解决此问题，如下所示：
如何删除大(Large)而不同的对象(Distinct Objects)
首先，围绕您的对象创建一个选择。根据您的图像，您可能需要花时间仔细选择对象。如果您的对象被明确定义，您可以简单地使用矩形选框工具(Rectangular Marquee Tool)来选择它周围的区域。
- 一旦您对您的选择感到满意（或者如果您已经使用选择创建了一个新图层），请从选项栏中选择 Edit 并单击Content-Aware Fill。
- 内容感知填充(Content-Aware Fill)工作区将向您显示预览。玩弄填充设置(Fill Settings)，直到您对结果满意为止。
- (Fix)使用修复画笔(Healing Brush)工具
修复任何意外结果。
如何消除干扰(Distractions)和不需要的小物体(Small Unwanted Objects)
移除小物体要容易得多。为此，您可以使用以下工具。这些中的每一个在不同的情况下都会更好地工作，所以如果一个没有给你想要的结果，试试其他的。
斑点修复画笔工具
要使用此工具：
- 从工具栏中选择污点修复画笔(Spot Healing Brush)工具。
- 在菜单栏中选择类型（内容感知(Content-Aware)可能是最好的）。
- 放大不需要的对象并刷过它。Photoshop将尝试用相似的纹理/颜色自动替换它。您可以通过按住Alt(Alt)、右键单击并拖动到左侧或右侧
来更改画笔大小。
补丁工具
要使用此工具：
- 选择修补工具。
- 在要删除的对象周围画一条线，然后将您的选择拖到与您希望它的外观相似的区域。Photoshop将尝试使用相似的纹理和颜色
填充您的选区。(Content-Aware Fill)
克隆图章工具
要使用此工具：
- 选择克隆图章工具。
- 按住(Hold)alt。您的光标应该变成十字准线。单击(Click)示例区域。单击下一步时，将粘贴相同的区域。单击(Click)并拖动将以完全相同的模式从周围区域刷出像素。
使用 Photoshop CC 创建完美的图像(Create Perfect Images Using Photoshop CC)
有了这个面向初学者的Photoshop教程，您将能够轻松地删除图像的背景以及人物、不需要的对象等。Photoshop提供了多种用于移除对象的工具和方法，因此，如果一种方法不能提供所需的结果，请尝试组合使用，直到完美为止。
How to Remove Backgrounds, Objects, and More In Photoshop
Phоtography is difficult. Unwanted objects, distracting elements, and imperfect backgrounds often mar an otherwiѕe great composition. Luckily, photo editing software like Adobe Photoshоp and Lightroom include powerful tools for easy image edits that enable you to easily remove these elements.
In this article, we’ll cover how you can remove backgrounds, unwanted objects, and more in Photoshop.
3 Ways to Remove Backgrounds in Photoshop
Depending on the complexity of your subject, background removal with Photoshop is relatively easy. In this section, we’ll describe various tools you can use to mask and isolate your subjects in Photoshop.
1. The Remove Background Tool
The easiest way to remove a background is by using Photoshop’s built-in removal tool. This method will work with clear-cut subjects but may struggle if there are no clear edges.
- Open your image in Photoshop.
- Duplicate the background layer by pressing Ctrl + J.
- Navigate to the Quick Actions panel and select the Remove Background button. To find this, scroll down in the Properties panel.
2. Use the Background Eraser
- Open your image.
- Click the Background Eraser Tool. It will be in the Eraser menu, so right-click the eraser tool to access it.
- In the Limits drop-down menu, select Find Edges.
- Click and drag along the edge of your subject. Take it slowly as the tool isn’t perfect and you may have to play around with the Hardness and Tolerance settings to perfect it. Once you’ve erased the background around your subject, you can easily delete the rest of the background.
3. Use Selection Tools
Photoshop has several selection tools that enable you to fine-tune your subject selection and isolate them from the background. These include:
- Magic Wand tool. If your subject is clearly defined, the Magic Wand tool will try to select it with a single click. You can then refine the selection using the Lasso or Brush tool.
- Object Selection tool. The Object Selection tool is similar to the Magic Wand, but instead, you drag a rectangular box around your subject and Photoshop will attempt to select it. You can then refine the selection.
- Quick Selection tool. The Quick Selection tool lets you paint in your selection as if you were using the Brush tool. You can then refine the selection afterwards.
- Lasso tool. The Lasso tool enables you to fine-tune your selection by adding or removing from it. Holding Alt (or Option on a Mac) while you click will remove the selection, while holding Shift will add to it. To use the Lasso tool, you need to create a circle around the area you want to add or remove. This is similar to the Pen tool but gives you far more control.
- The Select Subject tool. Photoshop has an automatic subject selection tool you can use. To access this, click the Select menu and click Subject.
Once you’ve selected your subject, you can further refine your selection using the Select and Mask workspace. To do so, click Select and Mask.
There are various tools you can use to perfect your selection:
- The Lasso and Brush tools. To add to your selection, make sure the add to selection button is selected. To remove areas, click the subtract from selection button.
- Refine Edges and Refine Hair. Click on Refine Edges to fine-tune any difficult areas. You can also select Refine Hair to let Photoshop refine hair selections automatically.
- Use Global Adjustments. If the edges of your selection look unnatural, under Global Refinements, you can change the Smoothness and Contrast sliders until the selection looks better.
Finally, in the Output Settings select Layer Mask and click OK. Your subject will now be in a new layer in the layers panel, meaning you can delete the background layer as required.
Note: Alternatively, once you’ve made your selection, you can create the inverse selection (by pressing Ctrl + I) so that you’re selecting the background. Then you can simply hit Delete to remove it.
How to Remove Unwanted Objects
There are several ways to remove unwanted objects in Photoshop. To cut out clearly defined and large objects, like people and animals, the best method is to use the selection tools to make selections.
However, once the object is removed, you’ll be left with a transparent background in its place. You can get around this using the Content-Aware Fill tool as follows:
How to Remove Large and Distinct Objects
First, create a selection around your object. Depending on your image, you may need to take your time to carefully select the object. If your object is clearly defined, you can simply use the Rectangular Marquee Tool to select the area around it.
- Once you’re happy with your selection (or if you’ve already created a new layer with the selection), select Edit from the options bar and click Content-Aware Fill.
- The Content-Aware Fill workspace will show you a preview. Play around with Fill Settings until you’re happy with the result.
- Fix any unexpected results using the Healing Brush tool.
How to Remove Distractions and Small Unwanted Objects
Removing small objects is much easier. For this, you can use the following tools. Each of these will work better in different scenarios, so if one doesn’t give you the desired results, try the others.
Spot Healing Brush Tool
To use this tool:
- Select the Spot Healing Brush tool from the toolbar.
- Select the type in the menu bar (Content-Aware is probably best).
- Zoom in to the unwanted object and brush over it. Photoshop will attempt to automatically replace it with similar textures/colors. You can change the brush size by holding Alt, right-clicking and dragging to the left or right side.
Patch Tool
To use this tool:
- Select the Patch tool.
- Draw a line around the object you want to remove, then drag your selection to an area that is similar to how you want it to look. Photoshop will attempt to Content-Aware Fill your selection with similar textures and colors.
Clone Stamp Tool
To use this tool:
- Select the Clone Stamp tool.
- Hold alt. Your cursor should turn into a crosshair. Click on a sample area. When you click next, an identical area will be pasted. Clicking and dragging will brush pixels from the surrounding area in the exact same pattern.
Create Perfect Images Using Photoshop CC
With this Photoshop tutorial for beginners, you will be able to easily remove the background of an image as well as people, unwanted objects, and more. Photoshop provides several tools and methods for removing objects, so if one method doesn’t give the desired results, try a combination until it’s perfect.
