What is a Rangefinder Camera?

In the photographic arms race, mirrorless systems are on the rise, having pushed DSLRs into the history books. But, just as film isn’t dead, neither are rangefinders. This seemingly obsolete design remains sharp, fast, and challenging enough to suit even the most confident photographers.

ISO in Photography: A Complete Guide

When compared to the other components of the exposure triangle (shutter speed and aperture), ISO appears to be the most intuitive on the surface. It is also the most misunderstood component, and everything from its definition to its usage has been discussed extensively.

What is EXIF Data in Digital Photos?

In the digital age, there’s a lot more to a photograph than the image itself. When most digital cameras capture an image, they record certain parameters and write them in the image’s file for later use. These parameters are called metadata and are stored as Exchangeable Image File data, or EXIF for short.

Camera Metering Modes Explained

One of the many features modern cameras have is a selection of modes for metering exposure. These allow you to choose how the camera measures the brightness of the subject or scene in order to automatically adjust camera settings for optimal exposure.

NFTs: An Introduction and Crash Course for Photographers

Ahh, NFTs… where do we even begin? What on earth is an NFT and why does that guy at the coffee shop with an ape on his sweater keep smugly talking about them? Does photography, a medium that we traditionally have come to understand as largely physical, have a place in this new format?

What Are Parabolic Light Modifiers and Are They Worth It?

Parabolic light has become increasingly popular among fashion and portrait photographers. With so many options to choose from, a photographer may get lost or not understand the modifiers at all.

Why Do Photographers Spend So Much on Monitors?

One of the most important tools in a photographer's toolkit is something many may be surprised by - a color-accurate monitor. But why are they so expensive, and why should a photographer spend so much on one?

What is the Difference Between a CCD and CMOS Camera Sensor?

A lot of words have been written and exchanged about the difference between -- and possible advantages or disadvantages of -- CCD (charged-couple device) and CMOS (metal oxide semiconductor + active-pixel sensor) camera sensors. What really is the difference between them?

Are Cameras Actually More Expensive Now Than Ever Before?

There is a purveying sentiment that cameras have only gotten more expensive over time. While there is certainly some validity in certain sectors of the market, the truth about camera prices over time is a bit more nuanced and complex than the average person makes it out to be. So, let’s take a look.

How to Mint an NFT: The Photographer’s Guide

The NFT craze from earlier this year isn’t going away -- but perhaps has become even more mainstream in the last three months. It’s hard to name a celebrity, artist, or athlete who hasn’t cashed in on the explosive popularity of NFTs.

How a Fresnel Lens Works, Explained with a Simple Blackboard Model

If you've heard of Fresnel lenses in photography before but have no idea what they are or how they work, here's a fantastic short primer. In this 3.5-minute video, physicist David G. Willey (AKA the Mad Scientist) explains the science behind the lens style using a simple and easy-to-understand model on a blackboard.

What is an NFT and Why Should Photographers Care?

Seemingly overnight, NFTs became the hottest acronym on social media and in headlines. On Thursday, a single JPG file created by Mike Winkelmann, also known as Beeple, sold in an online auction for $69.3 million. It was the first digital-only art sale for auction house Christie’s, meaning there was no physical copy involved.

Diffraction Explained: Why Your Lens is Worse at f/22 than f/8

It's common knowledge that most lenses are at their best (i.e. sharpest) between f/5.6 and f/8, depending on the lens. But why is that? Why does stopping down further actually make the image softer? This is what YouTuber ZY Productions explains in the video above.

Hypercentric Optics: This Camera Lens Can See Behind Objects

Engineer and YouTuber Ben Krasnow over at Applied Science has put together a fascinating little optical demonstration that explains the physics behind 'hypercentric' optics and how they allow you to see around and behind objects. He even shows you how to build your own.
