## 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.

## The Inverse Square Law of Light Explained in Simple Terms for Photographers

If the term "inverse square law of light" immediately sets you to hyperventilating as flashbacks of college physics begin playing in your mind's eye, take a few breaths into that paper bag, calm down, and click play on the video above.

In 6 minutes, Karl Taylor will explain this law and how it affects you specifically as a photographer without overwhelming you in the process.

## Understanding the Inverse-Square Law of Light

In this blog post, I would like to share some insights with you regarding the connection between aperture and the inverse-square law of light, as well as their effects on light fall-off.

## Portrait Photography Challenge: Shoot with a Flashlight and Phone

There can be a lot of gear-envy among photographers when they see others with tons of expensive camera gear, lighting equipment, and modifiers. It is also all too easy to say that you can’t be creative because you don’t have access to a particular light or piece of equipment.

## Why the Inverse-Square Law Might be ‘Wrong’ for Your Photo Shoot

Think you know the inverse-square law? How much of a "law" is it actually in the practice of photography? We are taught that the inverse-square law is the holy grail of understanding the laws of light. Some condense all the wonderful knowledge about light concepts to the inverse square law only. In this article, I want to invite you to take a step back and see how the inverse square law is wrong. Sometimes.

## How to Light Headshots: Five Tips from Peter Hurley

## Create Impossible Photos with a Lighting Composite

“Do you have 9 lights?” The account manager at Oakland University asked me. Somewhat inspired by a Queen album cover, he was looking to create an image where 9 award-winning students stood out in a dramatized version of a newly renovated space on campus. While I understood the goal of the session, I immediately knew rigging 9 lights up would be nearly impossible while showing such a vast space. I told him that it may take some time, but I could get it done with just 2 lights.

## Photographs Are Made With Light, Not Sensors and Tech

Great light is what creates great images.

What makes a photograph is not the camera sensor, or the autofocus system, or the depth of field. Photographs are made with light.

## How Many Studio Lights Do You Really Need?

When it comes to the quantity of lights that one needs, opinions are often heavily polarized and a hotly contested debate often rages. There are those that are staunch supporters of one light while others claim that a handful of lights are needed before anything meaningful can be done. Ultimately neither group is right as there is no definable minimum or maximum number of lights that one should use.

## Comparing the Max Power of Godox Strobes, Speedlites, and LEDs

Why is it so difficult to compare one light to another? It would be bad enough to say that watts, LUX, watt-seconds, and guide numbers aren’t directly comparable. And unless you’ve been around lights for a long time, these measurements won’t even make intuitive sense.

## 10 Tips and Tricks for Shooting Night Portraits with Off-Camera Flash

Portrait photographer Francisco Hernandez is back with a really useful tutorial on night portraits. If you'd like to start shooting some night portraits using off-camera flash, it would be a good idea to watch this first.

## Yes, Your Funk is Normal. No, It Won’t Last Forever.

The funk sucks. No matter who you are and no matter how long you've been at your art, everybody experiences the funk. Maybe you've even named your funk, mine is named Jeff. No real reason. Just feels a little bit more manageable whenever I've applied a name to it.

## How to Create White, Black, and Gradient Backgrounds in Photos

Creating an evenly lit background can be trickier than one would think, but is a skill that every photographer should master. But with the right equipment and knowledge, it gets much easier to capture a pure white, black, or colored gradient background in-camera without the need for heavy Photoshop cleanup in post.

## The Best Time of Day to Take Outdoor Portrait Photos

When is the best time of day to shoot portrait photos outdoors? Should we shoot only during the golden hours and avoid midday altogether, or is it better to use the brightest daylight hours to take our portraits with a few simple light modifiers? In this guide, we explore the best times of day for outdoor portraits.

## An Intro to Shadows in Photography

What is a photograph? There are many different ways to answer this simple question, but in basic abstract terms through the lens of lighting, every photograph is a combination of highlights and shadows. The only reason we see depth and dimension is in fact shadow. Understanding shadows is crucial in growing as a photographer.

## What Every Photographer Needs to Know About Reflections

Reflections are the sole reason we’re able to see objects. An object that absorbs 100% of the light is invisible. Fortunately, we don’t encounter these in our daily lives. Any lighting-conscious photographer would be aware of the fact that their light positioning directly influences reflection and hence the viewer experience.
