Diffuse back-scattering and the Opposition surge: The opposition surge, the significant increase of 180 degrees backscattered light, is a well-established and well-documented phenomenon. See "Opposition surge" in Wikipedia, and the references therein. On the other hand, there is no single true photo that obeys Lambert's Cosine law, "Lambertian reflectance" in Wikipedia. The first figure is an erroneous artist view. Urila (talk) 07:10, 10 October 2020 (UTC)[reply]
