ABSTRACT
Lens selection Having chosen the best position from which to take the photograph, select the appropriate lens for the job. This is likely to be a wide-angle lens, often the widest angle available because of the usual restrictions of space (not being able to get back far enough). It also gives the best depth of field and maximizes the illusion of space in a room by exaggerating the
distortion. The closer an object is to a wide-angle lens, and the further it is from the central optical axis of that lens, the greater the visual distortion and unnatural appearance of that object. For example, round plates in a bottom corner of the frame, photographed on a foreground table, can become awkward ovals sliding out of the composition. This can be further exaggerated by excessive shift movements, as any shift movement is a shift away from the central optical axis of the lens.
