Inverse Square Law of Light Explanation from Karl Taylor

Karl Taylor is back with another solid video. This time he’s breaking down the sometimes difficult-to-comprehend concept of the inverse square law into more understandable terms.

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.
