Shooting – The Basics
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.
z Compose each frame so that it overlaps
30 to 50 % of the adjoining image. Try to
keep the vertical misalignment to within
10 % of the image height.
z Do not include moving items in the
overlap.
z Do not try to stitch images that include
both distant and close items. Objects
may appear warped or doubled up.
z Make the brightness in each image
consistent. The final image will appear
unnatural if the difference in brightness
is too great.
z For good results, pan (swivel) the
camera to take successive shots.
z To shoot close-ups, slide the camera
over the subject, keeping it parallel as
you move.
