Photo math isn't math at all. It's arithmetic. It's adding and subtracting light. It's also either multiplying by 2 or dividing by 2. That's it. Photo arithmetic is easy. It all starts with a stop. What is a stop? A stop in everything but photography is coming to a complete halt. No movement. No motion. Photographically, a stop or more accurately an f/stop is a quantity of light. F/stop, by itself, always refers to an aperture value of a lens. F/8.0 is an aperture value. F/stops are used in relation to an amount of exposure to describe how … [Read more...] about Everything you need to know about photo math

When it comes to exposure in photography, it seems that most photographers have a reasonably good understanding of the impact of both the shutter speed and the lens aperture. But the role of the ISO setting can be a bit more mysterious. Of course, the shutter speed determines the extent to which motion in the frame is frozen or blurred. And the aperture primarily affects depth of field or the range of the scene that will appear in sharp focus. But what exactly does the ISO setting do? The need for speed The ISO setting on a digital camera … [Read more...] about Photography 101: What is ISO?
Shutter Priority exposure mode is a fantastic tool for controlling how motion appears in your final image. This exposure mode allows the photographer to set the shutter speed while the camera determines the aperture. Most DSLR and mirrorless cameras offer at least four different exposure modes including shutter priority, aperture priority, program mode and manual. Although I shoot the majority of my images in aperture priority, I regularly use shutter priority for subjects where I’m concerned about properly conveying motion. How to set up … [Read more...] about Shutter Priority and when to use it
In photography, ISO is a rating of your camera sensor’s sensitivity to light. A lower ISO like 50 or 100 means that the sensor will require longer shutter speeds and larger apertures to properly expose an image. A higher ISO like 1600 or 3200 will require shorter shutter speeds and/or smaller apertures to properly expose an image. What is Auto ISO? Almost all current interchangeable lens digital cameras give you the option to manually select an ISO value or to use a setting called Auto ISO. There are advantages to setting your ISO for a … [Read more...] about The advantage of Auto ISO
When just starting out in photography the typical person will begin their journey with the camera set to Auto. Using this mode tells the camera to choose the ISO, shutter speed, aperture, flash and focus. https://youtu.be/YUuwmeEhZu0 To be honest, the Auto mode has gotten much better over the years, and it can really lead to nice photographs. But the photographer still needs to think about composition and focal length. There is so much more to photography than simply clicking the shutter button and moving along. It’s an art and with … [Read more...] about 5 steps to get out of Auto
When we talk about photographing behaviors and events as they unfold, we think about being “reactive,” or shooting on the fly. In a studio setting, we are “proactive,” we make decisions about pretty much every characteristic of the photo before it is taken. My goal with wildlife photography is to be more “proactive” and make as many choices before the action begins as possible, so I am not fumbling with settings when the good stuff goes down! Be a “ready” photographer Being a “ready” photographer means you are prepared for the things that … [Read more...] about On Nature: What settings should I use for wildlife photography?
One question I'm asked a lot is "Where does all the noise come from when my camera is set to ISO 100?" The answer is simple. The photograph is underexposed. What is ISO? Grain vs. noise Back in the film days, the ISO (or ASA as it was called then) setting was the sensitivity of the film in the camera. While grain existed in every image, high ISO numbers produced more grain because the film had to have bigger chunks of light gathering chemistry. Today, the same idea applies. ISO in digital cameras refers to the light sensitivity of the … [Read more...] about Photography 101: How does noise happen at a low ISO?
In this article I show you how to setup your DJI drone camera, using the Go 4 app, in Manual Mode for shooting photographs. I will also talk about some of the settings you can change when shooting in manual mode, so you can explore and learn them. I will be using screenshots from my Inspire 2 as well as a video. Your screen may look a little different, but the basics are the same. Also, note that some drones don’t allow you to change the aperture. If Manual Mode isn't your thing, check out Full Auto Mode and Aperture Priority Mode. What is … [Read more...] about Becoming a Better Drone Photographer: Setting up your DJI Drone Camera in Manual Mode
In this article, I am going to show you how to setup your DJI drone camera, using the Go 4 app, in Aperture Priority Mode for shooting photographs. I will be using my Inspire 2. Your screen may look a little different, but the basics are the same. Also, note that some drones don’t allow you to change the aperture. What is Aperture Priority Mode? Aperture Priority Mode is where you tell the camera to use a particular aperture or f-stop and then it adjusts ISO and shutter speed to maintain that aperture. Why would I want to use that? With … [Read more...] about Becoming a Better Drone Photographer: Setting up your DJI Drone Camera in Aperture Priority Mode
I'm a part of several photography groups on Facebook, and some provide a suggestion to provide your camera settings for any photos you uploaded. Things like aperture, shutter speed and ISO, for instance. And while it can certainly be interesting to see these settings and see what they can do in certain situations, they don't matter in the long run. Settings Won't Help to Recreate a Photograph Unless you're shooting in a studio with no windows and can control the environment completely, settings won't be the end-all to recreating a … [Read more...] about Knowing the Camera Settings for a Photo Isn’t Really Important

(Editor's Note: This is a guest post from our friends at MPB.com. MPB is a great place to sell gear that's no longer in use as well as where to buy quality used photo and video equipment at much lower cost than that of new.) Photography is completely centered around light: it not affects your photo's mood, but it also dictates what your settings must be in the camera to record a picture and represent that mood in the picture. Let's talk about how shutter speed, aperture, and ISO setting affect your image, and then we'll dive into the … [Read more...] about Looking For Light from MPB.com
Let’s think technical for a moment. A properly exposed image is created by mixing three key elements, known as the Exposure Triangle—Aperture, Shutter Speed and ISO—to produce the right amount of lightness and darkness for a photograph. There are almost endless combinations that can be used to achieve an equivalent exposure. Leaving your camera in full auto mode will usually guarantee a perfect exposure, but not necessarily a perfect image. To be creative, a photographer decides how much of each element’s value to use based on the element’s … [Read more...] about Understanding Equivalent Exposure Pay attention – there’s a Quiz
At the Paralympic Games in Atlanta in 1996, digital capture was on the horizon. It wasn't ready for prime time. The photograph above is of the Canadian Tandem Cycling Team. The athlete on the right steers while her blind teammate adds power. They are multiple gold medal winners. I made their portrait on Kodak Tri-X film ISO: 400. This post is part of a series on photography's basics on the three components of exposure: Shutter Speed, Aperture and ISO. Before a discussion of any of these three pillars of exposure happens, a question has to be … [Read more...] about Photography’s Basics: ISO
Photographs are wonderful things, and one of their amazing characteristics is the detail we can see in a picture. I'm pretty observant of details in face to face contact, so I enjoy the fact that my camera can record those details with great clarity and I can share them with others. However, digital noise sometimes obscures the detail and can create distracting color specs that I find really frustrating. In fact, when I first started photography, I wouldn't raise my ISO above 400 for fear that noise would ruin the images. I'd like to share with … [Read more...] about Hate Noisy Pictures?
