 In J M Gandy's perspective of the Bank of England (see illustration at the beginning of this article), Gandy portrayed the building as a picturesque ruin in order to show the internal plan arrangement, a precursor of the cutaway view.A montage image is produced by superimposing a perspective image of a building on to a photographic background.Care is needed to record the position from which the photograph was taken, and to generate the perspective using the same viewpoint.
