Rectified Photography and Photo Drawings for Historic Preservation (Draft)

摘要

Rectified photography is a method which provides photographic negatives of a predetermined size or scale which can be enlarged to a convenient architectural scale, and which can be printed on photo sensitive drafting film for use as working drawings, surveys, feasibility studies, etc. Rectified photography, carefully done, can eliminate much of the time consumed in the measuring of complicated vertical surfaces. It is also possible to record ceilings using this method. The end result is a photograph of one wall or surface which can be scaled like an architect's drawing.
