Watermarking a picture is to add some transparent and translucent information symbols such as words, numbers, websites and patterns to the picture to identify the authenticity of the picture file and protect the copyright. The embedded watermark information is hidden in the main file of the picture, which does not affect the observability and integrity of the original file.

You can use image processing software such as Photoshop and Meitu Xiu Xiu to add watermark to the picture. Here, taking ps software as an example, the specific operation method of adding a watermark to a picture is as follows:

1. Open the picture with PhotoShop software, copy the layer, click the text tool on the left, set the foreground color, type, adjust the size and position with ctrl+t, and rasterize the text;

2. Double-click to bring up "Layer Style" and add the text "Bevel and Relief" and other effects;

3. Adjust the text layer, and adjust the "fill" degree to 0% and the "opacity" to 29%;
