title: Some photometric techniques for atmosphereless solar system bodies.
abstract: We discuss various photometric techniques and their absolute scales in relation to the information that can be derived from the relevant data.  We also outline a new scattering model for atmosphereless bodies in the solar system and show how it fits Mariner 10 surface photometry of the planet Mercury.  It is shown how important the correct scattering law is while deriving the topography by photoclinometry.
