10 horizontal images taken hand-held were stitched together for this panorama using Photomerge in Photoshop CS3. All exposures were 1/125 at f/8, ISO 400. The final image resolution is 11 x 62 inches at 300 dpi. Click on the image above to see a larger version.

Sweet – did you print this?
Planning to make a print — still working on dialing in the shadow detail for the high-res file.
How you’d get the clouds to line up between exposures? Fast work?
I put the camera on Live View with gridlines, and shot with 1/3 overlap. Total elapsed time between shot #1 and shot #10 was just over 1 minute. Photomerge in CS3 (and CS4) is hugely improved over CS2 — as long as there aren’t power lines or subjects quite near to the camera, everything lines up really well without any extra tweaking at all.
