I often get questions about how I take my killer panos.  Here's my secret:

  1. I take the pano on my iPhone with an app named, appropriately, Pano.  Although there are other pano apps out there, this is my favorite by far.
  2. Then, I import it into Camera+.  I apply the clarity exposure filter, then the diana overlay filter and use the cross-process border.

Here's the result!  You can also see my full 'killer panos' album on Facebook.
