Canon Photo Stitch is a cinch.

I've taken multiple panoramic shots before and stitched them manually in photoshop, sometimes its easy, other times it is a long process. I finally decided to get out my Canon Photo Stitch software and give it a try. As you can see the results of 7 photos I took while at the top of the St. Louis arch turned out pretty good. I still did some color matching afterwards in photoshop, but it was much faster than me doing it manually. (I couldn't get a correct curve on in the sky doing it manually) If you look close "I" can find imperfections cause I know where to look, but overall its something I will be using again.
