5. Apply the filter Polar Coordinates:

8. Rotate the selection 180 degrees. There are a few different ways to do this. One of them is to use the Edit menu, then Transform and Rotate 180 degrees.

9. Now apply the same filter we did in point 5. But do NOT just choose it from the top of the Filter menu. We are going to change one of the parameters so you have to choose it from Filters > Distort > Polar Coordinates… again.

This time, choose the upper radio button, labeled “Rectangular to Polar”:

Crop And Save

10. Crop your picture to get rid of the stuff surrounding your new circle:
