使用Photoshop(Photoshop)等程序可以轻松更改照片的构图。您可以使用程序中的裁剪工具来修复您的照片并让它看起来像您想要的那样。
但是，如果您是使用Photoshop的初学者，您可能会被这个程序的功能和工具的数量所淹没。所以做一些像裁剪这样简单的事情可能看起来很复杂。
您还可以通过许多不同的方式使用您以前可能不知道的裁剪工具。在本文中，您可以了解如何使用裁剪工具，以及拉直图像、使用网格和撤消裁剪。
如何在 Photoshop 中裁剪图像(How To Crop An Image in Photoshop)
- 找到裁剪(Crop)工具。您可以在工具栏中(Toolbar)找到它。它是带有两条直角线组成一个正方形的图标，如下所示：
- 选择裁剪(Crop)工具后，您将在图像周围获得一个边框，您可以从角落或侧面进行调整。或者，您可以在图像内部单击并拖出以自己制作边框。您需要在要裁剪的图像部分周围放置边框。(image)将保留边界的内部，而将外部删除。
- 如果您想在将要保留的区域内移动图像，您可以在最初移动裁剪边框后在边框内单击并拖动以执行此操作。对裁剪感到满意后，您可以选择选项(Options)栏中的复选标记或按键盘上的 Enter 。
您还可以选择重置或取消您的作物。您可以从选项(Options)栏中执行这些操作中的任何一个。要重置您的裁剪，请单击向后箭头图标。要取消它，请选择斜线圆圈的中间图标。
如果要裁剪图像(image)而不删除外部部分，可以通过更改删除裁剪像素(Delete Cropped Pixels )选项来实现。
为此，请查看选项(Options)栏，您可以取消选中此项。然后，当您裁剪图像并想要更改其方向或纵横比时，图像的其余部分将返回。使用这种方法，如果您以这种方式更改照片，则必须重新裁剪照片，因此请选择最适合您的工作流程的方法。
使用纵横比(Using Aspect Ratio)
如果您想在Photoshop中裁剪时获得更精确的结果，您可以更改图像的纵横比，使其精确。在选项(Options)栏中，您可以单击比率(Ratio)下拉菜单以查看纵横比预设。一旦你选择了一个，Photoshop会自动将你的裁剪边框设置为这个比例。您可以单击宽度和高度框之间的箭头图标来交换它们。
如果您想手动输入您的纵横比，如果您需要的没有出现在预设中，您也可以通过在宽度和高度框中输入数字来执行此操作。同样(Again)，Photoshop会自动将裁剪调整为您输入的比例。
如果您想保存输入的纵横比以供将来使用，您可以创建自己的裁剪(Crop) 预设(Presets)。这可以通过单击Ratio下拉菜单并选择New Crop Preset来完成。然后您可以为预设命名，下次打开“比率(Ratio)”下拉菜单时，它应该会出现在列表中。
如果您输入了纵横比，Photoshop会将裁剪选择方块锁定为该比例。因此，您可以在图像周围移动正方形，但不能随意更改大小。如果您希望能够自行调整正方形的大小，可以通过单击宽度和高度框旁边 的清除按钮来清除纵横比。(Clear)
如何拉直图像 (How To Straighten An Image )
裁剪工具也可用于理顺图片。选择裁剪(Crop)后，您应该会在选项(Options)栏中看到拉直(Straighten)工具。选择此项以在您的图像上使用它。
您需要在照片中找到一条线，它可以充当Photoshop的锚点，以将图像拉直。这可以是水平或垂直边缘，应该看起来是直的，例如水平线。
通过单击在该行的开头创建一个点，然后按住并拖动到另一端。释放后，Photoshop将拉直图像以使这条线笔直。它还将更改裁剪边框，以便您获得方形图像。
使用裁剪工具叠加(Using The Crop Tool Overlay)
您可能已经注意到在裁剪图像时覆盖图像的网格。如果您想要一些有关如何设置照片构图的指南，您实际上可以将此网格更改为多个其他网格。
默认覆盖是三分法(Rule of Thirds)。这是一个网格，旨在使您的照片在图像焦点位于相交点之一时令人赏心悦目。但是，您可以通过转到选项(Options)栏并选择看起来像网格 的叠加图标来更改网格。(Overlay)
您可以从Grid、Diagonal、Triangle、Golden Ratio或Golden Spiral叠加层中进行选择。这些可以帮助您在裁剪时使图像的构图令人赏心悦目。大多数这些背后的想法是眼睛倾向于以某种方式自然地沿着照片移动，如果你将图像的焦点放在这些自然点之一，则构图会更加流畅。
How To Crop In Photoshop
Changing the composition of a photograph has been made easy with programs like Photoshop. You can use the croр tool within the program to fix your photo and have it look the wаy yоυ want.
If you’re a beginner to using Photoshop, though, you may be overwhelmed with the amount of capabilities and tools this program has. So doing something simple as cropping can seem complicated.
There are also many different ways you can use the crop tool that you may not have known before. In this article you can learn how to use the crop tool, as well as straightening your image, using grids, and undoing a crop.
How To Crop An Image in Photoshop
- Locate the Crop tool. You can find this in the Toolbar. It’s the icon with two right-angled lines making a square, shown here:
- Once you select the Crop tool, you’ll get a border around your image that you can adjust from the corners or sides. Or, you can click inside your image and drag out to make a border yourself. You’ll want to put the border around the section of your image you wish to crop to. The inside of the border will be kept, and the outside deleted.
- If you want to move the image inside the area that will be kept, you can click and drag inside the border to do so after you’ve initially moved the crop border. Once you’re happy with the crop, you can either select the check mark in the Options bar or hit Enter on your keyboard.
You’ll also have the option to reset or cancel your crop. You can do either of these actions from the Options bar. To reset your crop, click the backwards arrow icon. To cancel it, select the middle icon of a slashed circle.
If you want to crop an image without the outer parts getting deleted, you can do so by changing the Delete Cropped Pixels option.
To do this, look in the Options bar and you can uncheck this. Then, when you crop an image and you want to change its orientation or aspect ratio, the rest of the image will come back. With this method, you’ll have to re-crop photos if you change them in that way, so do whatever suits your workflow best.
Using Aspect Ratio
If you want to get a more precise result when you crop in Photoshop, you can change the aspect ratio of your image so it’s exact. In the Options bar, you can click on the Ratio dropdown to look at the aspect ratio presets. Once you select one, Photoshop will automatically set your crop border to this ratio. You can click on the arrow icons between the width and height boxes to swap them.
If you want to manually enter your aspect ratio, if the one you need doesn’t appear in the presets, you can do this as well by entering the numbers into the width and height boxes. Again, Photoshop will automatically adjust the crop to the ratio you entered.
If you want to save the aspect ratio you entered for future use, you can create your own Crop Presets. This can be done by clicking the Ratio dropdown and selecting New Crop Preset. Then you can name the preset, and the next time you open the Ratio dropdown it should appear in the list.
If you have an aspect ratio entered, Photoshop will lock the crop selection square to this ratio. So you can move the square around the image, but you can’t freely change the size. If you want to be able to resize the square on your own, you can clear the aspect ratio by clicking on the Clear button next to the width and height boxes.
How To Straighten An Image
The crop tool can also be used to straighten out pictures. Once you’ve selected Crop, you should see the Straighten tool in the Options bar. Select this to use it on your image.
You’ll want to find a line in your photo that can act as an anchor point for Photoshop to straighten the image to. This could be a horizontal or vertical edge that should appear straight, such as a horizon line.
Make a point at the beginning of this line by clicking, then hold and drag to the other end. Once you release, Photoshop will straighten the image to make this line straight. It will also change the crop border so you get a square image.
Using The Crop Tool Overlay
You probably have noticed the grid that overlays your image when you’re cropping it. You can actually change this grid to multiple others if you want some guidelines for how to set your photo’s composition.
The default overlay is the Rule of Thirds. This is a grid designed to make your photo pleasing to the eye when the focus of the image is located at one of the intersecting points. However, you can change the grid by going to the Options bar and selecting the Overlay icon, which looks like a grid.
You can choose from Grid, Diagonal, Triangle, Golden Ratio, or Golden Spiral overlays. These can help you when cropping to get the composition of your image to be eye-pleasing. The idea behind most of these is that the eye tends to naturally move along a photo in a certain way, and if you put the focus of your image at one of these natural points, the composition flows much smoother.
