The Square Law (a.k.a. The Inverse Square Law)

Today, let’s talk about some of the physical aspects and how they influence our images and scenes.
One of these aspects of physics is called the ‚Inverse Square Law’.
Putting it in a simple way and if we are talking about point light sources or Fresnel lights, focusing lights, then the general rule can be stated as follows:
Double the distance - One quarter of the light
The square law as described so far, may prove to be perfectly applicable for point light sources or most of our focusing light fixtures that we use.
But it may not hold true for some different conditions and situations. Let's have a look.

This is the best explanation of the inverse law I’ve seen on KZbin. Thank you so much!!!

Brilliant! Thank you.

Reversing the light stand at 7:45 for super low angle : )
