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.

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?

I guess I should say the first time you use Autostitch there is a setup menu to visit. Among the options there is a resize image and you can specify an output length/width, just a maximum width, or just a maxiumum height. Autostitch has some AI in it. It does the compensation for barrel and pincushion distortion. It auto aligns the images without you specifying where they go. You do have to take the images in a logical order. You can even do a multi-row array. 25%-50% overlap images will give excellent results. Typically wide lenses put enough distortion into the photos that the output image will have some significant curves and bends around the sides. That is where the cropping comes in to play. Matter of fact in my tree you can see black corners in the upper left and lower right. That is the curved image output and I tried to maximize the image in the crop.

Let me check the software sub-forum if Autostitch has been discussed before. It could be a good new subject for a tutorial.

16 handheld shots stitched vertically using MS ICE. I couldn't get back far enough to get the right side of the tree.

Just go in your backyard and pick a tree or go downtown and pick a building. Anything works just to practice.
