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.

    When I initially commented I clicked the “Notify me when new comments are added” checkbox and
    now each time a comment is added I get four emails with the same

    Thank you!
