Change background Photoshop is one of the basic features that anyone should know when using this professional photo editing software. If you still do not know how to replace the background of a photo in Photoshop is also okay, please follow the article Tutorial to change the background image in Photoshop below.

Photoshop is a popular professional image editing software with a lot of useful features to help you edit photos. You can also change the background image in Photoshop to turn the desert wallpaper into a beach, turning the background image into a beautiful wallpaper.


The easiest way to change the background image in Photoshop is to separate the object to hold and the background. Photoshop has a lot of different tools that allow us to do that but in this article, we will use the Quick Selection tool in Photoshop CC 2017.

Step 1: Select the object to retain

Select the Quick Selection Tool on your left-hand toolbar, or you can use the shortcut W. You click and drag to select the area you want to keep, Photoshop will automatically predict the area you are. Want to keep based on the contrast of the image. In this example, we will keep the girl in the picture.

Before you proceed, you can resize the image in Photoshop to fit the background of the grafted image. Then, the tip of the photo size in Photoshop is quite simple, you refer to here resize the image on Photoshop.

You can also select a background to delete instead of selecting a retention object because it is easier to select the background than select the object to retain. You use the shortcut Shift + Ctrl + I on Windows or Shift + Cmd + I on the Mac to reverse the full area.

Finally, you will see the selection, but there may be areas of detail you do not want to select but still selected. This is normal because Photoshop is only predictable, we will edit the details in the second step.

Step 2: Adjust the selection area

To adjust the retention option that you have selected you zoom in on the image and select the size of the small brush to match the editing details by entering the selection in the toolbar above.

You can now select and adjust the selected area in more detail … or select to remove unwanted selections by holding down the ALT key and clicking.

Step 3: Mask the image with the Select and Mask tool

The purpose of using the Select and Mask tool is to clearly show the area you selected, so you can fine-tune the selection most accurately. You will find the Select and Mask tool just above the screen.

The result is that the selected image is selected, the selected part is transformed into a “mask” with a completely different color and contrasts with the selected part.

On the left is the Properties dialog box, the View mod will allow you to select the mask type. You choose which side you can see most easily. To me, In White is probably the ideal choice for you, you can press the F button to switch between different mask types during refining.

Step 4: Refine the selected area

Now you continue to refine and select other details like hair or other soft edges. You can select different tools on the toolbar on the left as:

Quick Selection Tool: As we used in Step 1, this tool can help you quickly adjust or remove the selection on your photo.

Refine Edge Brush Tools: This tool will be used to fine-tune regions such as hair strands or other soft edges.

Brush Tool: Used to adjust the hard edges on the image

Laso/Polygonal Lasso Tool: This tool will help you draw the area manually to add or remove parts in the selection.

You can now enlarge your photo by holding down the Alt key and rolling your mouse over. You will also see the selection is not accurate, missing or redundant. Use the tools above to refine and complete your retention selection.

Step 5: Adjust the settings

In the Select and Mask tool, another item that can be used to adjust the selection is Global Refinements. Some of the main features of this item are:

Smooth: smooth margins of the selection, remove the zigzag lines. Good for selection with clean border.

Feather: softens margins of the selection.

Contrast: Increases the contrast of the selection, only applies high efficiency when combined with Feather bar.

Shift Edge: Expand or collapse selections. When dragging the bar to the left, the selection is narrowed, and when dragged right, the selection is expanded.

Step 6: Remove the background

After you have finished refining the selection, select Decontaminate Colors in the Output Settings section. The Output to Normal option is automatically selected as New Layer with Layer Mask, if not automatically choose the offline.

Finally, just click Ok is finished.

If you stop this step, you will  make background transparent. 

Step 7: Paste a new wallpaper image

Next you paste the new background for the photo. Put it to the bottom of the photo containing the object that holds us up

You can use the Move Tool (V shortcut) to move a new background image or object so that it fits together. You can also use the Free Transform tool (shortcut Ctrl + T or Cmd + T), hold down the Shift key to keep the adjustment ratio even.

Step 8: Correct color

The final step is to modify the color of the object and the background to match each other. Select the layer containing the object and then select the menu item Image => Adjustments => Match Color.

In the Match Color dialog box, navigate to Source and select the image that contains the new background. Select Neutralize to remove all color from the selected layer and adjust the two Luminace and Color intensity so that the object and background color are the same color is. You can reduce the color effect by using Fade if needed. Finally click OK to complete.
