(geology)
A technique for ascertaining slope information from an image brightness distribution, used especially for studying the amount of slope to a lunar crater wall or ridge by measuring the density of its shadow.

The first technique, from which later the Photometric Stereo was derived, was called Photoclinometry which in short is the ability to create a shape from shading and therefore calculate elevation data (3D data) by analysing the shadows in the image.
We examine the morphometric characteristics by making use of a combined photoclinometry and shape from shading approach.
12) The iterative scheme used for photoclinometry and the SfS approach is described in our two preceding articles published in this journal, and is not repeated here.
Measuring the brightness of sunlight reflected from different parts of the terrain, the scientists used a technique called photoclinometry to determine differences in the surface elevation.
