Stitching
"Stitching" is the technical term for making panoramas. The
process involves taking a sequence of pictures (either horizontal or
vertical) and let the software "stitch" them together to make one scene
without the "stitches" showing.
"Stitching" relies on two techniques:
1.Move the camera horizontally (or vertically) on
the same plane. This is more easily done with a tripod and just
move the camera from the left to the right as you take the photos.
This keeps the camera parallel to the ground.
2.The second technique requires "overlapping" so
that the software can "stitch" on a reference point in each photo.
For example, if one of your frames has three people in it and you
aim the camera at all three, the second frame should have the third
person on the opposite edge of the photo! This means the person
on the right (in the first shot) and the person on the left (in the
second shot) provide the software with the same colors, shapes,
textures, etc. If you don't "overlap", you won't get a "stitch"!
Horizontal "stitching" is easier because usually the distances are
similar (except at the extreme edges) and will prevent distortion.
Vertical "stitching" is very difficult because if you're taking a
picture of, let.s say, the Eifel Tower, the distance to the top is very
much more than the distance to the base and this will cause distortion
called "parallax" which means not only are the distances different, but
the size is also different which makes it very difficult to "stitch" a
tower!
