Photoshop has great features that allow you to make almost any changes with the image. Blurred backgrounds are widely used by many photographers. In real life, this effect is achieved thanks to the functions of the camera. But when the picture is already taken, you can use the Photoshop graphics editor. This will be discussed in this article.

Preparation
Blurring the background in Photoshop takes place in two stages. It should be said right away that only minimal knowledge of this program is required from you. And even if this is your first time with Photoshop, then a ten-minute tour of all the most necessary tools will allow you to blur the background. You can use any version of the program. For this job, it is best to choose a high-quality image.
Instructions
The main idea of this method is to separate the background from the main part of the image, and only then apply filters to the desired area of the photo.
- Open the image in Photoshop.
- In any way convenient for you, stroke the part of the image that is notwill be blurred.
- I recommend using the Pen Tool (P). With it, you can achieve a more accurate selection. All further actions will be related to this tool.
- With the pen selected, start the selection. Try to follow the outer contour of the selected area of the image as closely as possible. Once the stroke is complete, connect the last selection point to the first. This is how you form an outline.
- Now you need to right-click on the path and select the "make selection" option. Set the feather radius to 2px in the dialog box. And click OK.
- Select any selection tool, for example the lasso (L). Right-click on the background area and find the option "invert selection". Thus, you have selected the entire background. For Photoshop, there is no standard means for performing this operation, so you have to use not quite standard approaches.
- In the top panel, find the "filters" tab, and select the "blur" function there. In the selected menu, find "gaussian blur". In this window, you need to specify the radius of action in pixels. Basically this value assigns 3-5 pixels. But you can put your numbers. It all depends on the situation and your preferences.

More information
You can additionally use the "blur" tool and slightly correct the mistakes made at the selection stage. If you used another method to create a selection, you can skip4, 5, 6 stages. The main thing is to understand that you need to separate the background from the main part of the photo. And how it will happen does not matter. Therefore, if you are better at using another instrument and do not handle the pen well, then it is better to use a tool that is convenient for you.

Conclusion
In Photoshop, you can perform a variety of operations with the image and change the background to your liking. Combine value and use new features. Fortunately, this program allows us to experiment endlessly and achieve the best result.
