Photoshop Pano Types?

I'm not clear on the type to select when stitching together a pano. "Auto" seems to work OK with the standard panos. What suggestions are there for using the Perspective, Cylindrical, etc. for landscape panos? I'm using CS5.

Wick - "Auto" is just selecting one of the other types for you based on the way the image appears to have been taken. If I don't like the way it chose to stitch, I'll sometimes try the other ones manually. Basically the different types are just different projection types and one isn't always more correct than another. Here's a great article on projections with regard to photo stitching from Cambridge in Colour.

I dont have CS5 but when stitching Panos I use CS3 I assume it cant be mutch different, and I use File>Automate>Photomerge and then I never use Auto almost 100% of the time I use Reposition Only and most of the time it will do a good job stitching the picture, occasionally I will manually do it but I find this way works pretty good
