The Inverse Square Law of Light Explained in Simple Terms for Photographers, Part II


A few weeks ago we shared with you the first part of a series Karl Taylor created, explaining the inverse square law of light. That is, the intensity of light given off from a source is inversely proportional to the square distance from the source. In the video he shares a number of examples, using a model and his own setup as a demonstration. Now, he’s back with part two.

In this follow-up video, Taylor briefly touches on his previous coverage of the inverse square law of light. From there, he dives right into the examples, wasting no time showing off a number of situations that weren’t covered in the first video.


Even if you understand what the inverse square law of light is, Taylor’s demonstrations do a great job of showing off how dramatically it will affect your work and how best to make use of it.

Part two comes in at four-and-a-half minutes. To catch up on the first part in the series, check out our previous coverage.
