  Asteroid photometry has three major applications: providing clues about
asteroid surface physical properties and compositions, facilitating photometric
corrections, and helping design and plan ground-based and spacecraft
observations. The most significant advances in asteroid photometry in the past
decade were driven by spacecraft observations that collected spatially resolved
imaging and spectroscopy data. In the mean time, laboratory measurements and
theoretical developments are revealing controversies regarding the physical
interpretations of models and model parameter values. We will review the new
developments in asteroid photometry that have occurred over the past decade in
the three complementary areas of observations, laboratory work, and theory.
Finally we will summarize and discuss the implications of recent findings.
