It's common to want to remove the background of a photo and just keep the subject. The subject of the photo can then be placed on an entirely different background. This guide will show how to erase the background of a photo using Photoshop CC. With the newest version of Photoshop CC, removing backgrounds is easier than ever!

想要?jiǎng)h除照片的背景并保持主題不變是很常見的。 然后可以將照片的主題放置在完全不同的背景上。 本指南將說明如何使用Photoshop CC擦除照片的背景。 使用最新版本的Photoshop CC，刪除背景比以往更加輕松！

First, make sure Photoshop is the correct tool for the job. If you just want to remove a background quickly, that can be done simply without Photoshop using one of these websites:

首先，請確保Photoshop是執(zhí)行此任務(wù)的正確工具。 如果您只想快速刪除背景，則無需使用以下網(wǎng)站之一的Photoshop即可輕松完成操作：

Here are the steps to remove a background with Photoshop.

以下是使用Photoshop刪除背景的步驟。

步驟1：在Photoshop中打開圖像。 (Step 1: Open your image in Photoshop.)

Open the image. If you have multiple layers, make sure the layer is selected that contains the background you want to remove.

打開圖像。 如果您有多個(gè)圖層，請確保已選擇包含要?jiǎng)h除背景的圖層。

步驟2：在“選擇”菜單中，單擊“主題”。 (Step 2: In the "Select" menu click "Subject". )

This will cause Photoshop to make a guess at a section of the the subject of the photos.

這將使Photoshop對照片主題的某一部分進(jìn)行猜測。

This does a pretty good job selecting the foreground, but there may be a few parts that need to be touched up. In the image below, arrows point to the parts that need to be improved.

這在選擇前景方面做得很好，但是可能需要修改一些部分。 在下圖中，箭頭指向需要改進(jìn)的部分。

步驟3：再次返回“選擇”菜單，然后單擊“選擇并屏蔽”。 (Step 3: Go back to the "Select" menu again and click "Select and Mask". )

This will open up a window that allows you to make adjustments to the selection.

這將打開一個(gè)窗口，使您可以調(diào)整選擇。

步驟3：調(diào)整檢視模式和不透明度。 (Step 3: Adjust the view mode and opacity.)

Try a few different options until you can clearly see the selected foreground. The exact options you should choose will depend on the colors in your foreground image and your personal preferences.

嘗試一些其他選項(xiàng)，直到您可以清楚地看到選定的前景。 您應(yīng)該選擇的確切選項(xiàng)取決于前景圖像中的顏色和您的個(gè)人喜好。

步驟3：調(diào)整邊緣檢測。 (Step 3: Adjust edge detection.)

This is useful for detailed selections such as hair. The Edge Detection pixel radius indicates that the edge, including all details, could be within that many pixels on each side of what is currently selected. If you select "Smart Radius", then Photoshop will automatically determine what the pixel radius is.

這對于詳細(xì)選擇(例如頭發(fā))很有用。 邊緣檢測像素半徑表示邊緣(包括所有細(xì)節(jié))可能在當(dāng)前所選內(nèi)容的每一側(cè)的像素?cái)?shù)之內(nèi)。 如果選擇“智能半徑”，則Photoshop將自動(dòng)確定像素半徑是多少。

步驟4：設(shè)置全局優(yōu)化，例如平滑。 (Step 4: Set global refinements such as smooth.)

Smooth is the main refinement you will need for photo editing. This will smooth out the jagged edges of the selection. You may also want to increase the feather, which will create a soft edge around the selection.

平滑是照片編輯所需的主要改進(jìn)。 這將平滑選擇的鋸齒狀邊緣。 您可能還需要增加羽化，這將在選區(qū)周圍創(chuàng)建柔軟的邊緣。

步驟5：使用左側(cè)的工具細(xì)化選擇。 (Step 5: Use the tools on the left side to refine the selection.)

The quick selection tool allows you to easily add or remove from current selection. For this tool and any brush tool you can use the bracket key to increase and decrease the size of the brush.

快速選擇工具使您可以輕松地從當(dāng)前選擇中添加或刪除。 對于此工具和任何畫筆工具，您可以使用方括號鍵來增大和減小畫筆的大小。

The refine edge brush tool will adjust the border area and is useful to add hair or other fine details to the selection.

細(xì)化邊緣筆刷工具將調(diào)整邊界區(qū)域，并且對于將頭發(fā)或其他精細(xì)細(xì)節(jié)添加到選擇中很有用。

The brush tool is used to fine-tune selections and the lasso tool is used to draw a free-hand selection.

畫筆工具用于微調(diào)選擇，套索工具用于繪制徒手選擇。

步驟6：確認(rèn)選擇并應(yīng)用圖層蒙版。 (Step 6: Confirm selection and apply layer mask.)

On the "Select and Mask" window, hit OK. Your foreground is now selected. To finish removing the background, hit the layer mask button to apply your selection to the mask.

在“選擇并屏蔽”窗口中，單擊“確定”。 您的前景現(xiàn)已選定。 要完成刪除背景，請單擊圖層蒙版按鈕以將您的選擇應(yīng)用于蒙版。

When you create a layer mask, the background is still available behind the mask in case you ever need it again. If you want to get rid of the background for good, you can copy the foreground and paste it in another image or you can invert the selection (choose Select > Inverse) and press 'delete' to permanently remove the background.

創(chuàng)建圖層蒙版時(shí)，在蒙版后面仍然可以使用背景，以防再次需要。 如果要永久去除背景，可以復(fù)制前景并將其粘貼到另一張圖像中，也可以反轉(zhuǎn)選擇(選擇“選擇”>“反轉(zhuǎn)”)，然后按“刪除”以永久刪除背景。
