2. Oren–Nayar reflectance model - Wikipedia

   en.wikipedia.org/wiki/Oren–Nayar_reflectance_model

   This model for diffuse reflection was proposed by Johann Heinrich Lambert in 1760 and has been perhaps the most widely used reflectance model in computer vision and graphics. For a large number of real-world surfaces, such as concrete, plaster, sand, etc., however, the Lambertian model is an inadequate approximation of the diffuse component.

   Earthshine – Light reflected from the Earth; Zodiacal light – Faint solar glow caused by interplanetary dust at sunset and sunrise; Gegenschein – Optical effect of interplanetary dust reflections; Reflection nebula – Clouds of interstellar dust which reflect the light of nearby stars

4. Lambertian reflectance - Wikipedia

   en.wikipedia.org/wiki/Lambertian_reflectance

   Lambertian reflection from polished surfaces is typically accompanied by specular reflection , where the surface luminance is highest when the observer is situated at the perfect reflection direction (i.e. where the direction of the reflected light is a reflection of the direction of the incident light in the surface), and falls off sharply.

5. Earthlight (astronomy) - Wikipedia

   en.wikipedia.org/wiki/Earthlight_(astronomy)

   Earthlight is the diffuse reflection of sunlight reflected from Earth's surface and clouds. Earthshine (an example of planetshine ), also known as the Moon's ashen glow , is the dim illumination of the otherwise unilluminated portion of the Moon by this indirect sunlight.

7. Glossmeter - Wikipedia

   en.wikipedia.org/wiki/Glossmeter

   Gloss meter in action. A glossmeter (also gloss meter) is an instrument which is used to measure specular reflection gloss of a surface. Gloss is determined by projecting a beam of light at a fixed intensity and angle onto a surface and measuring the amount of reflected light at an equal but opposite angle.
