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.

Lumos Hawk 150 LED Fresnel Provides 1K Output on a 150w Power Draw

Lumos 150 LED Fresnel-4

Lighting companies are really starting to do some cool things with LED lights. Several companies are starting to offer LED fresnel lights that run cool and deliver high outputs of light on a minimal power draw. Lumos’ Hawk line was on display at NAB 2014, where it was showing off a 150w and a 50w version of the LED fresnel lights. [Read more...]
