If you’ve been around photography for any length of time, you’ve probably heard of ISO. ISO is one of the three settings that determine our exposure in photography. These settings are collectively referred to as the exposure triangle. ISO is unique in this equation, and in this guide, we’re going to explore why.
ISO can be referred to in two ways. It’s most commonly spoken as an abbreviation, but it is also sometimes referred to as a word pronounced as eye-so. General consensus is that you call it whichever you like. After all, it’s not what

Photography is by definition, the capture of light on a light sensitive surface. That surface could be glass, tin, film, or a digital imaging sensor like those found in most modern cameras. The amount of light that reaches our light-sensitive surface is what we can define as exposure.
A good exposure will look accurate to life or the photographer's creative vision. It will maximize an images quality and

As you begin to research cameras, you’ll likely hear some technical jargon about sensors. While it’s easy to ignore some elements of any devices, there’s no way to work around sensors. But what is a sensor and what does it do? In this guide, we’re diving into the often confusing world of imaging sensors. By time we’re done, you’ll have a better understanding of the most significant component in our digital camera.

A lens’s hyperfocal distance—a mathematical combination of lens focal length, aperture or f-stop, and focus distance—is a tool that photographers can use to maximize their depth of field for capturing nearby foregrounds and distant backgrounds in acceptable sharpness.
While you can always dial up your lens’s sharpest aperture (sweet spot), many landscape photographers want as

After our introductory lesson to creating narrative and telling personal stories with smartphone cameras, I asked my kids to advance their skill set by telling visual stories using a more advanced, more versatile camera. In this case, they’re using my Sony Alpha a6500 mirrorless

ISO can be a sticky subject when it comes to video. It is used in photography when you have a great amount of control over your aperture, shutter, and exposure, and when you understand the lighting of your environment. But when used in video, if used too often, it can be more of an enemy than a friend to your footage. The most controversial setting is auto ISO, causing you to lose control over your ISO setting—and it can have mixed results. However, there are times when auto ISO can be your friend.

ISO, which stands for International Organization of Standards, is a measure of the sensitivity of film or a digital sensor to light.

Your camera is an extension of you in your studio. What you shoot with can be just as important as how you shoot. Choosing the right gear to help you perform better during a photo shoot is worth careful consideration. In this article, I will discuss cameras, but go more into depth on lenses, light meters, and care kits for your gear to help give you a better understanding of each and what features to look for when purchasing each component.

Over the past few years, pixel-shift image capture has transformed from a luxury reserved for deep-pocketed specialists to an increasingly common feature on new, resolution-oriented cameras. Today, in addition to Hasselblad’s behemoth Hasselblad H6D-400c, Olympus, Pentax, Sony, and Panasonic offer versions of the technology at much more accessible prices.
While it is advertised under several names (High Resolution Mode,

There is a great deal of confusion surrounding crop factor, and it is particularly difficult to explain, but let’s give it a try, shall we?
Before we dive in, let me dispel two vicious rumors related to crop factor that are circulating through the photography (Internet) world today:
Crop factor does NOT affect a lens’s focal length.
Crop factor does NOT affect a lens’s aperture.
Before you scroll to the bottom of the screen to leave a comment to the contrary, let me explain why I am stating these facts…

The primary measurement of a lens is its focal length. The focal length of a lens, expressed in millimeters, is the distance from the lens’s optical center (or nodal point) to the image plane in the camera (often illustrated by a "Φ" on the top plate of a camera body) when the lens is focused at infinity. The image plane in the camera is where you will find your digital sensor or film plate. If you are an optical engineer, this is important

When the term “dynamic range” is mentioned, many people will quickly think of HDR, or “High Dynamic Range.” With this term, and technique, so popular in the world of photography, it is rarely ever considered what dynamic range actually is, let alone why you would want it to be “high.” In short, dynamic range describes the measurement between maximum and minimum values. While not specific to photography, in this article on dynamic range in photography we can interpret dynamic range as the measurement between the whitest whites and the blackest

Before there was autofocus, there was focus. The camera is a light-tight box that is used to expose a photosensitive surface (film or digital sensor) to light. In order to focus the light onto the surface, most cameras (and your own eyes) use a lens to direct the light. Why did I say, “Most?” Well, there are many types of cameras around that do not rely on lenses to focus light. The “pinhole camera” is a box with a tiny hole on one end and a photosensitive surface on the other. Light comes through the tiny opening and is projected onto
