Inverse Square Law of Light Explanation from Karl Taylor

Inverse Square Law of Light Explanation from Karl Taylor

"The inverse square law in photographic lighting says, the intensity of light radiating from a source is inversely proportional to the square of the distance from the source. As a result, an object 2 meters away from a light source, receives only one-quarter the light as an object that is 1 meter away from the source. Check out Karl’s video embedded above for a practical demonstration of this principle. And notice how Karl demonstrates it by shortening the ratio of distance between the two subjects and the light source. "

"To reinforce Karl’s video again, the inverse square law in photographic lighting says:  the intensity of light radiating from a source is inversely proportional to the square of the distance from the source. As a result, an object 2 meters away from a light source, receives only one-quarter the light as an object that is 1 meter away from the source."
