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.

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.

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.

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.

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.

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.

A Glossary of Lighting Terms Used in Photography

When starting out in photography, you are bombarded with terms, definitions, and a whole new universe of things you must know as a photographer. Sometimes the definitions are confusing at best, seemingly conflicting at worst. When it comes to lighting, there's a big list of terms and jargon that you need to know. Here are some of the common ones with simple definitions and explanations.

Lighting 101: Everything You Need to Know About Light Fall Off

Photographer Gavin Hoey recently produced a video for Adorama TV that tackles a critically important subject for photographers: light fall off. Mathematically captured by the so-called Inverse Square Law, it's vital that photographers understand this property of light, especially when working with strobes.

Using Water to Explain the Properties of Light and the Exposure Triangle

Photographer Robert Hall recently released a simple-yet-brilliant explainer that uses water to illustrate the properties of light and explain a few concepts that frequently confuse beginners, including: what is a "stop" of light, how do you use the exposure triangle, and how do various flashes and flash modifiers affect your image.

3 Things Most Photographers Get Wrong About Flash

In this video, we’ll talk you through 3 common misconceptions when it comes to flash. These are easy mistakes any photographer can make so pay attention and see how to correct them with these easy tips!

The $10 Backdrop: Cheap vs Expensive Seamless for Portraits

Photography. It’s expensive. And who really has the money to buy all the name brand photo gear? I certainly don’t. With that said, expensive equipment does NOT make the photograph -- the photographer does, which is why I am exploring various non-photography-specific gear and using it for my photography.

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.

iPhone 7 Plus Camera Review: iPhone JPEG vs iPhone RAW vs Sony A7R II

As a full time professional photographer, I try to remind people that the best camera you have is the one you have with you. Since I have yet to permanently graft a DSLR onto my body, my best camera is often my iPhone. So, is the new iPhone 7 Plus good enough to help alleviate the anxiety I get every time I leave my camera at home? Let’s find out!
