Scene illumination multiplied by reflectance. This is the amount of light returned to the camera and determines the quality of picture.
Light bounced off a subject, not falling on it. Often occurs on even, polished surfaces. In contrast, diffuse reflection occurs on uneven surfaces, when light scatters.
Light reflected by the subject into the lens of the camera.
This is light that is bounced off another object usually a wall or a ceiling or it can be part of a fitting or bulb. It comes from a directional light source usually but has the light diffused by the reflection. Rather than a spotlight shining directly on an object, the light is bounced off a wall or ceiling to subtly and/or softly illuminate rather than receive the full intensity of directional light.
Light redirected from an opaque object or surface. The amount of light reflected depends on the angle at which the light strikes the object, the smoothness of the surface, and the color of the surface.
Light that bounces back from the object that it strikes.
The scene brightness or the light being reflected from a scene. Usually it represents 5 to 95 percent of the incident light, and it is expressed in foot-lamberts.
Light that bounces off a surface or subject before being seen or recorded.
This is light that has been deflected from an opaque surface, object or material. The light is reflected from the object instead of being absorbed by it.
