Cameras and Lenses
Any camera can produce images for stitching. Digital cameras are easier to use in most cases, but film scans also work. Higher resolution originals, of course, yield richly-detailed final images. For sweeping landscapes and 360° x 180° (full sphere) panoramas, use a wide angle lens with a focal length of 28mm (35 mm equivalent) or wider. Some programs, such as RealViz's Stitcher, can even use circular fisheye shots. For 2-D panoramas (stitching rows and columns) of specific objects, use a telephoto lens (80-200mm lenses often work well). This allows you to make extremely high resolution images of all kinds of subjects.
