In panoramic imaging, the cylindrical projection is most often used for prints of wide panoramas which occupy large range (>120 degrees) of longitude. Like the Equirectangular Projection, the cylindrical projection also preserves verticals, but it cannot represent data near the poles (nadir and zenith), which are distorted and stretched further and further to infinity. It can however be used to display more than 360 degrees horizontally: scanning cameras often record a little bit more than 360 degrees so the overlapping region is easier to be stitched if light changes or something moves in that area. Multiples of 360 degrees can e.g. display a changing subject like different seasons.
