1. The mobile app store searches for "P picture every day". Click to download and install the mobile phone software shown below.
2. After the installation is completed, open it and enter the home page, as shown in the figure below. If the background needs to be replaced, we choose the "magic matting" tool;
3. Under the pop-up scene selection, click to select any scene (the scene is only some background special effects, and if it is only changed to a white background, no special effects are needed), and then select the picture that needs to be keyed from the album, as shown below, and we select a photo;
4. Click "Smudge" in the lower left corner and use the smudge tool to select the selection. The selection area is the main body of the image that we need to dig out. Paint the parts that need to be cut out, and erase the parts that need to be painted with an eraser. The mobile tool can adjust the position of the picture, and the mobile hand can enlarge or reduce the picture with two fingers to adjust the smearing accuracy. After daubing, click the checkmark in the red area below to select the image.
5. The following figure shows the cut image. Here, please pay attention to prepare a pure white photo or picture with your mobile phone in advance, select "custom background" in the red box, and then select a pure white photo or picture prepared in advance from the album.
6. The photo after changing the background is shown in the figure below, and the size and angle of the portrait can be adjusted at will (this is just a sign, and the frame of the portrait without careful adjustment is a bit rough, so the subject can try more). Click the download sign in the upper right corner, and the picture will be saved on the phone.
7. The preserved photos are as follows:
This completes the replacement of the white background.
