      Hi Shawn,

      I think you will find that John is talking about the same tool.

      )>>No need to guess. You can measure the vertical limits on the Panorama
      )>>Editor window.
      )
      )I think he's talking about the readout in the lower left corner.
      )When you're looking at your pano in the editor window, you can use the
      )sliders on the right and left to mask(or hide) the portions of
      )your pano
      ) that isn't covered by your shooting.
      )So, if you use the right slider and get a reading of 110' for
      )the second
      )number(and you're not seeing any black in the Editor window),
      )your pano has
      )vertical coverage of +/-55.

      Paraphrasing what you wrote and following what John wrote: (I hope I get
      this right John)

      So, if you use the right slider(and you're not seeing any black "*at the
      top*" in the Editor window) and get a reading of 110' for the second number,
      your vertical coverage for the "top" half is 110/2 (or 55)
      and then,
      if you use the right slider(and you're not seeing any black "*at the
      bottom*" in the Editor window) and get a reading of 130' for the second
      number, your vertical coverage for the "bottom" half is 130/2 (or 65)

      ) Some qualifications are needed here-
      ) Your pano's horizon has to be straight across the Editor window.

      correct

      ) If you shot your pano tilted a little up or down(uneven vertical
      )coverage
      ), you'll have to guess on one of the limits because the Editor
      )window only masks evenly from top to bottom.

      partially correct.
      If you take two readings, you don't need to guess.


      Cheers,
      Darren.

      )In setting the tilt limits I did it by trial and error. Is there a
      )way to see in advance where to set the tilt limits? In the panorama
      )preview is show the vertical angle of view and how much is black so
      )my first guess was 1/2 that angle. But I couldn't see anyway to
      )decide more accurately before generating the .mov panorama.
