Use mobile phone retouching software to repair portrait photos into a pure black background. The operation steps are as follows:

1. We use mobile phone retouching software Snapseed to open portrait photos.

2. Click Tools, find the curve tool and click it. In the curve tool, click the button behind the error symbol, and in the white menu that pops up, select the brightness curve.

3. Drag the brightness curve interface, the point in the upper right corner, to the lower right corner, so that the photos are all black and no one appears. Check the number and save this step.

4. Use Snapseed mask to display the portrait, leaving a black background: click the curved arrow in the upper right corner, and then click the pop-up menu to view the changes. The previous operation steps appear on the right, and the first one is "curve".

Click on the curve and three buttons with blue background will appear. Click on the middle brush. This brush is the masking function in Snapseed that does not label Chinese characters.

5. After entering the mask interface, adjust the curve value to 100 and smear the portrait. First smear the farthest position from the edge of the character and the position near the edge of the character, and then enlarge the picture to the maximum.

Be sure to zoom in to the maximum, and then smear the edges of the characters. After daubing everything, export and save it.
