What is a Panorama Photo?

I guess it makes sense to try to define what is a panorama (on Panogio). The type of images expected to be found on Panogio are very wide, typically with an aspect ratio of 2 to 1 or similar, commonly known as panoramas. (We won't define exactly what the ratio should be but leave that to you - the users.)

Wikipedia defines Panoramas as this: A panorama (from Greek <πανοραμα>) is any wide-angle view or representation of a physical space, whether in painting, drawing, photography, film/video, or a three-dimensional model.

The different panoramas supported by Panogio:

Spherical: A equirectangular panorama with 2:1 ratio and a view of 360°x180°.

Cylindrical: A 360° image (usually differs from equirectangular by missing top and bottom).

Partial: A wide image but with a view of less than 360°, typically one side has to be significantly greater than the other (compare to TV screens where a 16:9 aspect ratio is called wide screen).

What about Vertoramas and Panography?

Vertoramas are vertical panoramas i.e. the height is greater than the width. On Panogio i Vertorama could be a cylindrical or partial panorama and is treated no different than the horizontal panoramas.

Panography is a more "artistic" way of creating panoramas. There is still no support for this kind of panoramas on Panogio but if you are into Panography and wish to show your work here please let me know and I will do my best to add it to the site.

Single image or multiple images stitched together?

Most likely the panorama images posted on Panogio is stitched together from several exposures with software as Hugin, PTGui or Autopano. Since the minimal width required when uploading is 1000 pixels the image could be a cropped photo from a two mega pixel camera, but that would probably make a boring panorama.

There are special panorama cameras on the market that off course could be used to create the images, but they tend to be analog and not that common any more.

Please keep your uploads to images that you believe is a panorama. If you are in doubt after reading the text above, please have a look at the images submitted by other users and you will get the idea.
