From 2008. It was a very large tree as I recall. Picnic Point on University of Wisconsin-Madison campus. I used a stand-alone freeware called Autostitch to assemble 4 images. It is still my go-to tool for stitching photos. Just import the jpg images and let it rip. It's that simple, other than some crop afterward normally.

How do you set the output size: width, height, scale? Say your four individual images are 6000x4000 each, will you set output size as: 6000, 15000, 100%? When let it as default (2000, 1000, 100%), I got a wide top, narrow bottom skewed (vertical) pano. The question is: in this case (vertical stitch), how do you determine an accurate height output dimension? It, I think, has to be less than 4 times of original height due to the overlap area. But how less? or just set it x4 width?
Marilynne, I didn't know that one could do vertical stitching with MS ICE since I never had a reason to try it. Does the program automatically sense the matching image interfaces or do you need to rotate the images 90 degrees before loading them to get the proper result?
Thanks. Now I need to find a subject to try it on.
