How to blur the background with Photoshop

The way to blur the background with Photoshop is:

1. Open ** and copy the layer;

2. Use the "Polygon Lasso Tool" to select the ** theme;

3. "Select--Modify--Optimize" 2 pixels;

4. "Choice--Reverse Selection";

5. "Filter--Blur--Gaussian Blur", adjust the blur value, and you're done.

First, open a ** and select the Polygon Lasso tool in the toolbar.

Step 2: When the mouse becomes a polygonal lasso shape, use the left button to operate, click the left button on each point to turn and then continue to select, until the whole shape becomes selected, when you reach the connection port, the lasso will have one more circle next to it, double-click the left button to turn the whole subject into the selected state (within the dotted line).

In the third step, it is the background that we want to do to blur the effect, so at this time, we need to choose the background of the inverted selection. In the menu bar-Select-Invert, the background area is surrounded by dotted lines, that is, the selected state.

Step 4: Menu Bar - Select - Feather Why use the Feather function, wait a moment and then make a comparison.

Step 5: After pressing the feather menu, a window will pop up, feather pixels (10) pixels. I wrote the wrong size of the feathered pixel here, depending on the size of the original picture, for example, the size of the original picture is 2048x1536 pixels, the feathered pixel (50) pixels The original image size is 600x450, and the feathered pixel (10) pixels This is my personal habit, you can set it yourself according to the situation.

Step 6: Menu Bar - Filter - Blur - Lens Blur (It is recommended to use Lens Blur, which is closer to the effect of shooting the lens than Gaussian Blur, but the processing speed is very slow, you can try to do it yourself with Gaussian Blur, compare it).

After selecting the lens blur, the following window will pop up, adjust the radius to the appropriate number, and press it to you're done.

Adjust the number of radius, for example, if the size of the original picture is 2048x1536 pixels, the radius (30-50) If the size of the original picture is 600x450, the radius (10-15) pixels This is my personal habit, you can set it yourself according to the situation.

Finished picture, things to pay attention to: everything must be mastered, and the blur effect must also be mastered, and it will be self-defeating if it is excessive. If you don't need it too much, it's best not to use PS for this kind of post-processing, I think as long as the background is good-looking, it looks good without blurring.

This finished picture, which has not been feathered in the middle, clearly shows that there is a dividing line between the clear part and the blurred part. With the feathering effect, you can make the blurred points gradually transition and create a realistic image.

The second method is to make a background blur: the first step is to open a new image and left-click on the quick mask in the toolbar.

Step 3: Click to exit the quick mask and see that the background area is framed by a dotted line. Go to the menu bar - Filter - Blur - Lens Blur.
