Photomerge hiccup??
 

Today i merged 13 images to make a panorama and the end result was an image that looked more like an accordian........all pics were like a constantina effect.
Imagine a pack of playing cards all standing up but 45 degrees to each other...it looks strange.

This is the first time i have used this many images.... all my previous panoramas have had up to 5 images....whats going on ???

What software did you use?

CS5 photomerge
13 raw images.
