Digital photo processing example: use Photoshop to Process Photo backgrounds

Legend 1. Digital Photo source with a background
 

Example 2: Remove a digital photo of interference in the background.
 

How to use Photoshop to process the photo background and steps:

Use Photoshop to process the background of a photo. Step 1. Copy the layers.
 

Step 2. Filter → blur → Gaussian blur.
 

Step 3. Set the Blur radius (you can click preview to select an appropriate parameter)
 

Step 4. Set the opacity of the copy layer to around 80%.
 

Step 5. Use an eraser tool to erase the entity to be retained. This process requires patience, and the nuances of the eraser should be very small.
 

Step 6. slowly wipe the subject, and then set the opacity of the copy layer to 100%. (It can also be another number, which should be determined based on the actual situation)
 

Step 7. Finally, merge the layers and process a digital photo that removes the interference background.
 

If the background of the image is relatively different from the subject, and the subject is relatively single-click, the processing will be much simpler. After opening an image with Photoshop, you can use the magic wand tool (or the plug-in tool) to select the background (or select the subject and then select another one ), then, you can use the Blur tool to process "lens blur" or "Gaussian blur.
