Adding a nadir cap (mirror ball)

I wrote a Photoshop action that produces these mirror spheres below out from an equirectangular panorama.
As you can see are three sizes available.




Small covers 5% ,Big 8% and XXL 12% of panorama height (equirectangular projection)
Below you can see the region that will be covered with the mirrorball.




Here the action set in Photoshop:



Download the Photoshop action here:
Media:cap.atn

A similar action with text:
Media:cap_text.atn

For a flexible nadir cap which can be streched to your needs:
Media:CapFlex.atn
