A fundamental concept in the production and viewing of both partial and full spherical panoramic images is the type of input and output projection used.  See [[Projections]] for more information.  It is the projection of photographic images and resulting panoramas which explains why the simple method of aligning and taping together snapshots cannot produce seamless panoramic images (though it can be quite enjoyable in its own right).

Panoramas are an exciting creative application of photography and recently, of computing. Panoramas offer a unique, immersive perspective to the viewer. To the photographer, panoramas present an interesting artistic and technical challenge.

Panoramas come in different shapes and flavours, so let's set a definition. A dictionary tells us a panorama is "a picture (or series of pictures) representing a continuous scene". This continuous scene can come straight from a (special) camera or it can be assembled from multiple images using the panorama tools.

Technically three different types of panoramas are distinguished

Partial panoramas

(this needs text, guys)

Cylindrical panoramas

(this needs text, guys)

Immersive panoramas

Immersive panoramas are panoramas that allow you to look everywhere around you, including straight up and straight down. Immersive panoramas come in two subflavors, spherical and cubic ones. (this needs text, guys)
