Inverse square law
A simple mathematical law that's usually complicated by its description. The law states that light projected onto a surface is inversely proportional to the square of its distance from the source! See what I mean?

The Inverse Square Law
What it means to Photographers
It's useful to know a little about the inverse square law especially when using flash or studio lights.
INVERSE SQUARE LAW - An equation that relates the intensity of a light source to the illumination it produces at a given distance.
Inverse Square Law
The quantity of light falling on a subject is inversely proportional to the square of the distance from the source
Interpolation ...
Inverse Square Law This law of physics indicates that when you increase the distance between a subject to twice as far away from a light source, it will then receive one quarter of the light. Find out more.iPhone App.
Inverse square law. The physical law that causes light from a flash to fall off in such a way that as flash to subject distance doubles, the light falls off by a factor of four.
inverse square law
The inverse square law is commonly used in sound, photography and video to predict how energy will reduce as distance between the source and the measuring device increases.
Inverse square law. When a surface is illuminated by a point source of light the intensity of light at the surface is inversely proportional to the square of its distance from the source.
Inverse square law
A law of physics that states that light from a point source fall off inversely to the square of the distance.
The Inverse Square Law illustrates how as the distance from the flash doubles, the amount of light on a given area falls to one-quarter because the same amount of light has to cover an area four times as large.
Inverse Square Law.
This is the law of diminishing luminance that states that light reduces by the inverse of the distance squared.
Inverse square law - states that, when the light source is a point, illumination on a surface is inversely proportional to the square of the distance of the light source.
Two powers come from the light traveling a greater distance and the inverse square law, one power comes from the exit pupil of the lens being tilted and looking like an ellipse rather than the full circe, ...
Without getting into the specifics of the Inverse Square Law, this essentially is due to the fact that the hard light is so close to the set. Think of the sun, 93 million miles away.
The actual relationship between distance from the light source and size of the imaginary sphere can be described mathematically as the inverse square law. It states that light output is proportional to the inverse square of the distance.
Fall-off (source) see Inverse Square Law.
False Ceiling
A Translucent material stretched above a Set which Transmits light, but which appears solid from below.
The further the subject is from the window, the Inverse Square Law kicks in and the light level falls off four times as it travels twice the distance. Photo (#2) was taken in a very dark room in India.
(If a ringflash is used from a farther distance, the entire body gets the same amount of light. Only at shorter distances, due to the inverse square law, will I get the desired fast falloff of the light.) ...
Oh yeah and if you are a strobist, that triangle becomes a square because you have to also take into account the amount of light from your strobe and the "inverse square law" that can affect the lighting in your images.
INVERSE SQUARE LAW-The intensity of light received at a point (irradiance) varies inversely as the square of the distance from the source. The law holds for relatively small sources only and is useful in calculating photographic exposures.
