Abstract
The present inventions directed to a method and apparatus of scan-photographing a subject such as a model, in which a three-dimensional subject having a depth such as a model is projected on a sensitive film while being scanned through an optical system having a lens and a slit integrally incorporated therein, and the subject is then photographed in a plan view (hereinafter referred to as orthographically projected photograph) at a predetermined photographing magnification without being effected by the view angle of the lens, while the subject and the sensitive film are travelled in parallel with and in the opposite direction to each other at predetermined speeds, respectively.
