The Inverse Square Law of Light, Explained in the Simplest Way Possible

Let’s face it; we’re not scientists and the name of this law could frighten many of us. The reality is that this is a very basic concept with a very technical name: the inverse square law of light.

When it comes to lighting subjects, whether you’re a wedding photographer of a feature film cinematographer, the possibilities given to you are endless. Sometimes you don’t know how you want to photograph something just because you might not know whether you’re doing it in the best way possible. With so many different ways to light something, it’s pretty easy to start doubting yourself, and it happens to us all the time.

This video can do a lot to help out with that. By learning exactly what this concept is, you can narrow down your choices to what’s best suited for your subjects; the best part is it’ll require only about ten minutes of your time. Photographer Karl Taylor puts this tutorial together in the most simple way possible to give you an idea of how the inverse square law of light affects your photography. The first clip gives an overview of how the lighting affects the subjects in a photo the farther the source of light is placed, and the second one goes over how the background of the picture comes in relation. Without wasting any time at all, the guy behind this video gives you a quick and easy way to understand a simple concept; no matter what kind of photographer you are, you can benefit from what he’s got to say.

    I’m no expert at making instructional videos (and I’m on my phone with WiFi, so I can’t watch it), but “about 10 minutes” does NOT sound like “the simplest way possible”. :-)
