What is illumination science?
In a general sense, the science of the application of lighting. … In a specific quantitative sense, illumination is the combination of the spatial density of radiant power received at a surface and the effectiveness of that radiation in producing a visual effect.
What is illumination and reflectance?
Illumination is the amount of source light incident on the scene. It is represented as i(x, y). Reflectance is the amount of light reflected by the object in the scene. It is represented by r(x, y).
What is the difference between illumination and light?

- Incandescence produces light by heating a substance.
- Electroluminescence produces light as a result of an electric current passed through a substance.
- Cathodoluminescence produces light as a result of being struck by an electron.

How do you calculate reflectivity?
Calculate reflectivity. Reflectivity can be calculated as p(y) = Gr(y)/Gi(y) where p is the reflectivity, y is the wavelength of the light, Gr is the reflected radiation and Gi is the incident radiation.
What is illumination in image processing?
The illumination of the subject of a drawing or painting is a key element in creating an artistic piece, and the interplay of light and shadow is a valuable method in the artist’s toolbox. … In contrast, a single light source, such as harsh daylight, can serve to highlight any texture or interesting features.
What is the difference between luminance and reflectance?
With a non-luminous surface e.g. a wall, what the eye sees – the brightness or luminance of the surface – depends on the reflectance i.e. the ratio of reflected light to incident light. … Illuminance (lux) x reflectance = luminance (apostilbs).

What is the law of illumination?
The law states that Illuminance at a point on a plane is proportional to the cosine of the angle of light incident (the angle between the direction of the incident light and the normal to the plane). … The maximum Illuminance occurs when the element of area receives the light flux normal to its surface.
How is illumination calculated?
Average illumination E = Flux required on the working plane / Area of the working plane E = Flux output by each lamp x No. of lamps x U.F. x D.F / Area STEPS OF LUMEN OR FLUX METHOD OF CALCULATIONS 1.
