I make a full circle pictures, but you end up with a truncated view, the circle is not closed. What's up? But I have obtained and closed pan, but I can not find a connection. What hinders? Thank you.

Hi, michael_ulyanov,  
    If your camera is at the center of your circle and you pivot around, try a little more overlap. About 1/3 works well for a panorama.  If your subject is at the center of your circle, and you walk around it a panorama won’t work.  Try to make a Photosynth, start here by uploading the photos you have.  http://photosynth.net/create.aspx
      Also if you use the Advice & Critiques forum you may find more people willing to help you.
                                             Good Luck, Waldos Digital World
