To merge the images on a computer, use PhotoStitch, one of the supplied programs. Framing a Subject The PhotoStitch program detects the overlapping portions of adjoining images and merges them. When shooting, try to include a distinctive item (landmark) in the overlapping portions. • Compose each frame so that it overlaps 30 - 50% of the adjoining image. Try to keep the vertical misalignment to less than 10% of the image height. • Do not include moving items in the overlap. • Do not try to stitch images that include both distant and close items. These items may appear warped or doubled up in the merged image. • Make the brightness in each image consistent. The final image will appear unnatural if the contrast in brightness is too great. • To shoot landscapes, swivel (pan) the camera around its own vertical axis. • To shoot close-ups, slide the camera over the subject, keeping it parallel to the subject as you move it.
