These are the specific steps to add a watermark to iPhone 13. When adding a watermark, you should pay attention to the following points:

The watermark should not be too prominent, so as not to affect the beauty of the picture.

The location of the watermark should be appropriate, and don't block the important part of the picture.

The content of the watermark should be concise and not too complicated.

If you need to add multiple watermarks, you should pay attention to coordinating the overall effect.
