Stretch: The Art of Panoramic Photography

It covers compositional issues (finding subjects that fit the shape and making the most of them); technical considerations (exposure measurement, avoiding flare, etc); and the various types of equipment that can be used. Much of the book is practical, but it is also illustrated with panoramic pictures. It opens with a gallery of images, and there are interviews with a selection of panoramic photographers, discussing their approach and equipment. The volume has a fun, modern look and should be useful for anyone with an interest in panoramic photography.
