Since inverse square law is so universal and useful, let’s examine it in more detail, and try and illustrate it with some real world examples. Don’t forget, since it’s a fundamental law of light, you can’t escape it, but you can learn to work with it and around it. Let’s start with the hyopthetical “Big Group Shot”
Understanding inverse square law is really useful, so I apologise if I keep going on about it! To be honest, it’s something I really struggled with when I started, so perhaps I’m just overcompensating for my own lack of comprehension.
We’re nearly done though, for our last example, let’s examine how the same principle works on a smaller scale.
