The Pano function on the iPhone is a wonderful innovation which I am well aware that appeared on other smartphones first.  However, as I don’t use any other smartphone is somewhat irrelevant.  The function offers some great creative opportunities but also has a number of problems associated with it, uppermost being that is  works the best in optimal lighting conditions and when you go beyond this the image quality plummets.  Given a caveats I still feel that the Pano function  is one of the best additions to image making on the iPhone.
