[3] [4] [5] He was first to state that the incident ray, the reflected ray, and the normal to the surface all lie in a same plane perpendicular to reflecting plane. [6] [7] Specular reflection may be contrasted with diffuse reflection, in which light is scattered away from the surface in a range of directions.
Defined as the ratio of the specularly reflected light to that diffusely reflected normal to the surface; Absence of bloom – the perceived cloudiness in reflections near the specular direction; Defined as a measure of the absence of haze or a milky appearance adjacent to the specularly reflected light: haze is the inverse of absence-of-bloom
Diffuse interreflection is a process whereby light reflected from an object strikes other objects in the surrounding area, illuminating them. Diffuse interreflection specifically describes light reflected from objects which are not shiny or specular. In real life terms what this means is that light is reflected off non-shiny surfaces such as ...
Port with the disembarkation of Cleopatra in Tarsus (1642), by Claude Lorrain, Musée du Louvre, Paris. Light in painting fulfills several objectives like, both plastic and aesthetic: on the one hand, it is a fundamental factor in the technical representation of the work, since its presence determines the vision of the projected image, as it affects certain values such as color, texture and ...
It is the fraction of incident electromagnetic power that is reflected at the boundary. Reflectance is a component of the response of the electronic structure of the material to the electromagnetic field of light, and is in general a function of the frequency, or wavelength, of the light, its polarization, and the angle of incidence.
Reflection of light is either specular (mirror-like) or diffuse (retaining the energy, but losing the image) depending on the nature of the interface.In specular reflection the phase of the reflected waves depends on the choice of the origin of coordinates, but the relative phase between s and p (TE and TM) polarizations is fixed by the properties of the media and of the interface between them.

The later Pentax Spotmeter V and Digital Spotmeter indicated directly in EV for ISO 100, but they made no mention of "light level", "light value", or LV. A synonym for incident light value, from the Additive system of Photographic EXposure . Zakia and Stroebel (1993) and Stroebel, Compton, Current, and Zakia (2000) used the term in this sense.
