Inverse Square Law of Light Explanation (Part 2) from Karl Taylor

A couple weeks back we saw a video from Karl Taylor where he gave a very straightforward and understandable explanation for the inverse square law of light. The above video is the second and final part of the discussion from Karl.

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.

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.

4 Lighting Tutorial Videos from Karl Taylor

Karl Taylor has been working on a multi-part series of lighting tutorials for Broncolor. He just published the fourth video in the series on YouTube.

In the fourth video, he shows off some expert dual flash techniques by using a long exposure in a dark studio to fire strobes at different times while removing modifiers in the dark. Really smart stuff.

You can see part one above and the next three in the series are below.  [Read more...]
