photoshop 裁剪_如何在Photoshop中裁剪图像
photoshop 裁剪
Cropping photos is one of the most basic, but important, photo editing skills. A crooked horizon or something distracting on the edge can ruin a great image.
裁剪照片是最基本但最重要的照片编辑技巧之一。 歪斜的地平线或边缘上分散注意力的东西可能会破坏良好的图像。
I’m going to show you the basics of how to do it in Photoshop, however, the tools are very similar in any other good image editing app.
我将向您展示如何在Photoshop中进行操作的基础知识，但是，这些工具在其他任何出色的图像编辑应用程序中都非常相似。
This is the image I’m using.
这是我正在使用的图像。
I love it, but there are two problems. First, there is too much of the land in the bottom right corner; I want the image to be cropped tighter to the lighthouse. Second, the horizon is crooked. I’ve highlighted that in pink below.
我喜欢它，但是有两个问题。 首先，右下角的土地太多了； 我希望将图像裁剪得更紧贴灯塔。 第二，地平线是歪曲的。 我在下面用粉红色突出显示了这一点。
The way to fix both of these problems is with the Crop Tool.
解决这两个问题的方法是使用“裁剪工具”。
使用裁剪工具 (Using the Crop Tool)
Select the Crop Tool from the Tool Bar or press C on your keyboard.
从工具栏中选择裁剪工具，或按键盘上的C。
Once you’ve selected the Crop Tool, you’ll see something that looks like this.
选择“裁剪工具”后，您将看到类似以下的内容。
The dotted outline represents the new crop.
虚线轮廓代表新作物。
You’ve two options. First, you can use the cursor to drag a new crop around any area of the image you want.
您有两个选择。 首先，您可以使用光标在所需图像的任何区域周围拖动新的裁剪。
Second, you can drag in from any of the handles to adjust the crop. If you hold down the Alt or Option key, the handle opposite will move in as well. This is the more accurate option.
其次，您可以从任何手柄中拖动以调整裁剪。 如果按住Alt或Option键，则相反的手柄也将向内移动。 这是更准确的选择。
If you select a ratio, like 2:3, in the upper left corner of the window, the other edges will move in as well to keep the aspect ratio the same. To constrain the crop to the original ratio, hold down the Shift key while you drag. To change the ratio, select the one you want from the Ratio drop-down in the Options bar.
如果您在窗口的左上角选择一个比例，例如2：3，其他边缘也将向内移动以保持长宽比不变。 要将作物限制为原始比例，请在拖动时按住Shift键。 要更改比率，请从选项栏的“比率”下拉列表中选择所需的比率。
You can also enter your own.
您也可以输入您自己的。
To swap the two values, click the two arrows icon. To reset the ratio, click the Clear button.
要交换两个值，请单击两个箭头图标。 要重置比率，请单击“清除”按钮。
To rotate the crop, click and drag anywhere outside the crop boundary.
要旋转作物，请单击并拖动到作物边界之外的任何位置。
To move the crop, click and drag anywhere inside the crop boundary.
要移动作物，请单击并拖动作物边界内的任何位置。
Before we finish, look at the top of the window, and you’ll see a few options.
在完成之前，请查看窗口顶部，您将看到一些选项。
The Delete Cropped Pixels checkbox should almost never be checked. If it is checked, when you crop the image anything outside the crop boundary is deleted. This means you can’t re-crop the image at a later point. It’s safer to just leave it unchecked.
几乎不应选中“删除裁剪的像素”复选框。 如果选中，则在裁剪图像时，裁剪边界之外的所有内容都会被删除。 这意味着您以后无法重新裁剪图像。 取消选中它会更安全。
If Content-Aware is checked, Photoshop will attempt to automatically fill any blank areas left by the crop. It can work if the area Photoshop tries to fill in is really simple like a blue sky, but it’s best not to rely on it. Just crop your image within the boundaries.
如果选中了Content-Aware，则Photoshop将尝试自动填充农作物留下的任何空白区域。 如果Photoshop尝试填充的区域真的很简单，例如蓝天，那么它可以工作，但是最好不要依赖它。 只需在边界内裁剪图像即可。
The three icons on the right only appear when you’re cropping an image. Click the Checkmark icon to accept the crop, the Cancel icon to cancel it and the Reset icon to reset the current crop. You can also use the keyboard shortcuts Enter or Return to accept the crop and Escape to cancel it.
右侧的三个图标仅在裁剪图像时出现。 单击复选标记图标接受裁剪，单击取消图标取消裁剪，然后单击重设图标重设当前裁剪。 您也可以使用键盘快捷键Enter或Return接受裁剪，并使用Escape取消裁剪。
使用拉直工具 (Using the Straighten Tool)
In our example image, we not only want to put the lighthouse closer to the center of the frame, but rotate it so the horizon is straight.
在我们的示例图像中，我们不仅要使灯塔更靠近框架的中心，而且还要旋转它以使地平线是直的。
While I could straighten the horizon by eye, there’s a better way to do it.
虽然可以直视地平线，但是有更好的方法。
To straighten the horizon in an image, select the Crop tool and then click the Straighten button in the Options Bar.
要拉直图像中的地平线，请选择“裁剪”工具，然后单击选项栏中的“拉直”按钮。
Click at one point on the horizon and then drag your cursor so the line follows the horizon.
单击地平线上的某一点，然后拖动光标，使直线跟随地平线。
When you release your cursor, Photoshop will make that line the new horizon.
释放光标时，Photoshop将使该行成为新的视野。
To accept the straightened image, press Enter.
要接受拉直的图像，请按Enter。
And there you have it, a perfectly cropped and straightened image.
在那里，您可以得到完美裁剪和拉直的图像。
With the number of megapixels in a modern digital camera or smartphone, you have a lot of leeway with how you crop your images. If the horizon isn’t straight or you want a tighter framing, go ahead and fix it in Photoshop. You now know how.
随着现代数码相机或智能手机中的百万像素数量，您在裁剪图像方面还有很多余地。 如果地平线不平整，或者您想要更紧密的取景，请继续并在Photoshop中修复它。 您现在知道了。
