How to make a full watermark when transporting photographic works?

The PS operation steps of full-image watermarking are as follows:

1. Open your watermark image with PS, click Edit-Define the pattern, the name of the pattern (it doesn't matter whether it is modified or not), and click OK.

2. Open the picture of the work that needs to be watermarked, and click Edit-Fill, or press the shortcut key shift+F5 directly. Note that the fill options need to be modified here. Select "pattern" for the content, then click the custom pattern, find your watermark in the custom pattern, usually the last one, select it, and then check the script. It has many forms, generally choose "brick filling" and "mixed mode"

3. At this time, jump out of the value of the tile, and adjust the pattern scale, spacing and line displacement according to the size of your picture and watermark. The rotation angle of the pattern is generally -45 degrees, of course, you can set the parameters several times according to your own preferences. If this step is not ideal, you can set the parameters several times. Finally, click OK to finish the whole image watermarking.
