Abstract: | When photographs of outcrops are required for detailed and/or accurate structural work the photographic image should be parallel to the outerop surface. A method has been developed which allows oblique photographs to be corrected when processed. The method imposes certain restrictions on the combinations of camera and enlarger lenses which will yield a correctly proportioned print, and graphs are presented which predict suitable combinations for a wide range of conditions. The technique has been successfully applied to several problems, one of which is presented as an illustrative example. |
