发明名称 Photographic distortion method and apparatus
摘要 A method and apparatus for obtaining a distorted photographic reproduction from a negative photographic image, in which a sheet of photosensitive printing paper is attached to a planar surface of a table, the image negative is placed over the paper and a slitted mask is placed over the image negative. The image negative and the mask are moved laterally relative to one another and to the paper while the mask is exposed to a light source. To obtain a circular reproduction the mask is held stationary and the printing paper is rotated about an axis intersecting the slit while the image negative is moved laterally with respect to the slit.
