How to spell seamlessly with ps

The production method of that seamless puzzle is as follow:

1. Find a picture first and open it in PS.

2. Open the filter-Other-Displacement, as shown in the figure below.

3. As shown in the figure, first set the offset value (try it yourself if there is no definite value) and you will see that there will be obvious boundaries, which is exactly what we want to remove. Adjust it at will, and pay attention to the gap in the picture.

4. Use the stamp tool to adjust its opacity and size, and delete the boundary line. Be careful in this step, and pay attention to let the texture be natural.

5. There is no boundary line in the dotted oval box. As you can see, no matter whether you set the horizontal value or the vertical value this time, you can't see the boundary line.

6. Well, save it as JPEG. You can use it this time. Try 3d.
