Panorama is actually a wide picture of any scenery. It has been introduced to figure out a wide angle photo and commonly finds in every smart phone these days. So I really like the article about panorama photography and hope that others will like it too.
Yes, smartphones have some panorama ability. But they are a bit limited, eg you can only shoot a single row with a phone.
With stitching technique you can shoot multiple rows (this one consists of 2 rows), to not only get more width into one pivture, but also mote hight.
The biggest scope I managed so far was 360 degree horizontal, and about 170 degrees vertical view.
