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.
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.
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.
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.
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.
When it comes to headshots, there is perhaps no better source of information and guidance than the man who has made an empire out of the practice. In this five minute video on the, Peter Hurley quickly breaks down his favorite tips to light the perfect headshot.
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.
Light can be one of the most challenging topics when it comes to learning photography. It takes a lot of trial and error to understand light, as there are very few resources available that teach light beyond setups.
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.
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.
“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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
As display technology has improved in leaps and bounds over the past few years, the market has forked into two distinct camps: gamers who prioritize speed, and creators who prioritize color. The 32-inch 2K MSI Creator PS321QR tries to strike the perfect balance between these two needs, offering a compelling combination of refresh rate, response time, and color accuracy for just $700.
You didn’t ask to learn about bellows extension factors, but we're going to cover it with the most absurd camera that you may ever see!
Do you want to switch from Canon to Sony? From Sony to Nikon? From Nikon to Panasonic? From Panasonic to Fujifilm? Well, I’m going to ask you to stop, take a deep breath, and consider doing the most boring thing: absolutely nothing. Instead of switching camera brands, you should probably stick with what you have.
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!
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.
Mystified by talk of "guide number" and "flash power"? Gerald Undone made this helpful 10-minute video that explains everything you need to know about the light from strobes and speedlights, from common misconceptions to practical formulas that will help you light your shots.
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!
In a recent article, I spoke about the best ways to perfectly light your background with colored gels. We covered the best things to keep in mind if strong and vibrant colors across your backdrop are your objective. It turns out that gelling your background is actually relatively simple -- it's keeping those strong vibrant colors that's actually the tricky part.
Summer is coming and that means one thing for many photographers: the dreaded midday sun! Fear not people, you can use that harsh light to your advantage.
One of the most important aspects of fine art macro photography is capturing a non-distracting background so your subject stands out. I tend to like clean and colorful backgrounds, but there are situations where dark backgrounds may be desirable. This article will showcase one method of how to capture black backgrounds in macro photography. We’ll take a look at using flash falloff.

I keep meaning to post reviews about my gear. I’ve been lucky enough to shoot for years with some of the best lenses in the world. I hold strong opinions on them and rarely do those opinions make it beyond my own inner dialogue.
This time I’m doing it right away. This morning, March 3rd, 2015, I got that ever exciting knock on the door from my FedEx guy. In his hands was a much bigger box than I had envisioned. What lies within it was Canon’s newest drool-worthy lens, the 11-24mm F4L.
One of the first things that we learn when we start taking photographs seriously is that ‘aperture’, the size of the hole in the lens through which light passes, controls depth of field.
A large aperture creates shallow depth of field while a narrow one creates wide depth of field. But there’s a little more to aperture than that, let’s take a closer look at this most fundamental photographic control.
Thank God, I am now a gear minimalist focused on photography and a big fan of "limitation creativity" (i.e. you are more creative with less)... But here’s the truth, I used to be a huge gear junkie, basically having Gear Acquisition Syndrome (G.A.S.) as soon as I got a new camera. I had this problem since the very beginning, but now I am cured. In one sense I am trying to help those who know they have G.A.S. to stop having it and trying to prevent others from having it.
Dear (new’ish) Model,
My name is Other Model. I have spent the last couple of years finding out a few things that I wish I’d known from the start. Please don’t think I’m patronising as I mean this only in goodwill, as there is absolutely no gain for me by sharing these cheats. Not all of my points will be valid for you as posing varies in each genre. Just take what you can and ignore the rest. If only one suggestion helps your future career then my time has been well spent…
If you have 20 minutes to spare and would like to learn all about how to shoot long-exposure photos showing landscapes and starry skies, check out this primer by adventure photographer Kamil Tamiola. Titled "Let There Be Light," the video steps through many of the fundamental aspects of long-exposure night photography, from choosing the right environment to choosing the right gear.
