Ultra wide angle lens the difference is only whether distortion is present or not. However, the shorter the focal length, the more difficult it is to implement rectilinear correction. In fisheye lenses, the visual angle is close to or more than 180 degrees in at least one direction. For example, a "diagonal fish eye" would have a viewing angle of at least 180 degrees within the diagonals of the frame. A "circular fisheye" would represent the image in the form of a circle. Rectilinear ultra-wide angle lenses are used in photography and cinematography sometimes to achieve three-dimensional perspective distortion instead of simply two-dimensional barrel
36 Degrees a performance "The average body temperature is 37 degrees. This is a song called 36 Degrees", further adding to the speculation. However, the term "36 degrees" also means two people who are not getting on in urban slang; therefore the idea of the song being written for a break-up could well be true. The other numbers mentioned have been said to just be random, as "they just seemed to fit" according to Molko. The music video, directed by Chris Cunningham, was shot primarily in a scuba diving pool and shows band members performing the song underwater. Some scenes were shot
