Stitching is the art (and technology) of putting together multiple photographs taken from a single location but with varying orientations, in order to produce a much larger image of that location. The technique to do this encompasses more than just cutting the photographs and matching them at the edges - it requires complex transformations and processes for blending the overlapping areas. All this is taken care of by sophisticated software and the problems that the artist faces are quite different. For example, to take these photographs you need a sunny day, but on sunny days the air warms up and creates atmospheric turbulences (the Fata Morgana effect you see in the desert or when driving along a highway on a warm day).

Here are two great examples of this type of extreme photography:

• Prague in 18 Gigapixels (360°), photographer Jeffrey Marti, founder of www.360Cities.net
• Paris in 26 Gigapixels (180°), photographer Arnaud Frich (read in his blog how he did it).
