oblique photography oblique photographyA type of aerial photography in which the camera axis is deliberately kept tilted from the vertical by a specified angle. The photographs, thus taken, reveal details masked in some ways in vertical photographs. The main function of this type of photograph is intelligence; these photographs cannot be used for mapmaking because of their large-scale errors. There are two types of oblique photographs: (i) high oblique—one in which the apparent horizon appears—and (ii) low oblique—one in which the apparent horizon does not appear. See aerial photography, low oblique, and high oblique. |
