I was just sent a link to a great stitch program and it works great.
Microsoft ICE
I love taking panoramic photos as it allows me to get more of my subject into the digital photos. This puts it all together.
Always leave a little of the previous shot into the second and so on shot to get the program to piece them together. I always used Photo Sticth but this one did it automatically and with finer results. I will use it as a primary and photo stich as a back up.
