I don't know why I haven't tried this before... here's a panorama of the Charles River from the Back Bay in Boston.
This 180-degree photo is actually made up of five "normal" images I took with my 18-55mm zoom at it's widest setting. Equivalent to a 28mm lens on a 35mm camera, it's not a superwide by any means. But coupled with the PhotoStitch software that came with my Canon DSLR, I was able to create this panorama in a few minutes. The resulting image was 13,530 x 2142 pixels, or about 28.6 megapixels.
I did this on the spur of the moment last weekend while in Boston for a wedding, without giving it much thought, but here is a good article by Ken Rockwell on using PhotoStitch. Ken notes that even the least expensive Canon digicams made in the last two years, come with this software. The digicams even come with a special "stitch assist" mode to make life easier still.
I see this as a good technique for making some dramatic panoramas in Annapolis and Baltimore. Look for some soon.
