This Video Explains Exactly How Lens IS and IBIS Work in Modern Cameras

Most photographers know the basics of lens-based image stabilization (Lens IS) and in-body image stabilization (IBIS), but if you've ever wanted a technical deep-dive that explains exactly how these systems work to generate 4, 5, or even 7 stops of stabilization, this video from Imaging Resource is here to answer that call.

How Canon’s New Defocus Smoothing Gets You Ultra-Creamy Bokeh

Canon announced the new RF 85mm f/1.2L DS IS lens for its full-frame mirrorless cameras today, and the $3,000 lens is the very first Canon lens to feature a new technology called Defocus Smoothing (DS). If you're curious about the new lens tech, check out this 1.5-minute video by Canon that introduces it.

This is How Film Cameras Added Dates to Your Photos

Before EXIF data landed on the scene through the rise of digital photography, film cameras could superimpose the current date directly onto your photos, allowing you to see when you shot each one as you flipped through an album. If you've ever wondered how that date was included, here's an interesting 14-minute teardown by Applied Science that reveals the secret.

Explaining Bit Depth and Debunking a Common Myth

Each year, someone new comes along to try and demystify bit depth for the masses. In 2017 it was Tutvid, in 2018 Greg Benz did a great job in this article, and now StyleMyPic has created a comprehensive and easy-to-follow video that explains exactly what bit depth is, how it works, and debunks a common myth.

How Google’s Handheld Multi-Frame Super-Resolution Tech Works

Since there are physical limits to how large sensors can be in smartphones, companies like Google have been pushing heavily into computational photography, the use of digital rather than optical processes to improve the capabilities of a camera. Here's a 3-minute video that explains how Google's super-resolution technology works.

The Pros and Cons of Syndicating Your Photos

For a while now, I’ve wanted to cover the topic of syndication as it was a major factor in my work gaining widespread exposure and for the full-time career that I have now as a fine art, commercial, and editorial photographer.

How Camera Film Gets Processed in a Lab

I was recently fortunate enough to get an inside and ‘behind-the-scenes’ look into how film processing works at Richard Photo Lab in Valencia, CA. As the step by step process is very complex, if you’ve ever wondered what the stages of film developing are and look like, come and take this video tour with us!

What National Geographic Photo Editors Actually Do

Have you ever wondered what the photo editors at National Geographic do? No, they don't sit around and edit pictures in Photoshop. In this 6-minute video, some of the biggest names in photography offer a glimpse into the closely-knit relationships between photographers and their editors.

How DSLR Phase Detection Autofocus Works

Most photographers rely heavily on the capabilities of autofocus systems in DSLR cameras, but knowing how they actually work is something that even experienced photographers may not have learned. Here's a 4-minute video by ZY Productions that helps decode the mystery of DSLR autofocus by explaining the technical details behind it.

The Magic of Polarizing Lens Filters for Your Camera

Polarizing lens filters help your camera see the world in a new light... literally. If you've never used a polarizing filter before, check out this great 3-minute video by photographer Christopher Frost in which he discusses why these filters are so neat and how to use them.

Tilt-Shift Lenses: How They Work and How to Use Them

Everybody knows tilt-shift lenses can be used to get a "miniature" effect, but many photographers are oblivious to their other, more traditional applications, and even fewer understand exactly how these lenses work. The folks at LensPro ToGo are here to clear things up.

A Simple Explanation of How Lenses Work

Canon just released this 3.5-minute video that explains how lenses work. We learn about focal points, spherical aberration, chromatic aberration, and how multiple lens elements are used together for aberration correction.

Video: How Automatic Film Processing Labs Work

Back in the heyday of film photography, a common part of the photography experience was dropping off your film rolls at a store or lab, placing the roll in an envelope and checking boxes with instructions for what you'd like. Here's a fascinating 5-minute video that reveals what happened to your film between drop off and delivery of your prints and processed film.

This is How Canon Flips the Mirror in Its New DSLRs

If you shoot with a DSLR, you might take for granted that the mirror inside your camera swings out of the way to allow light to hit the sensor. There's actually quite a bit of precise engineering behind those seemingly simple flips.

With its new Canon 5DS and 5DS R, Canon introduced a new mechanical mirror mechanism that's designed to reduce mirror flip vibrations. The 43-second video above shows how the system works.

Tutorial: A Basic Explanation of What a Tilt-Shift Lens Is and How it Works

Tilt-shift lenses are nothing short of optical magic... or so it seems. But as their namesake implies, they actually achieve this 'magic' through the use of two clever movements in the lens.

In the short tutorial above, Vincent Laforet, a Canon Explorer of Light and well-known photography educator, explains just how those two components work and how they dramatically impact the look of an image.

Disassembling a Tripod Ball Head to See How It Works

This will probably be of limited interest to most of you, but we like to know how things work, not just how well they work. We thought we’d take a couple of pictures when we disassembled a ballhead in case any of you were interested. Our demonstration partner today was a Benro B1 ballhead that had a stripped tension adjustment knob, but all ballheads work basically the same way.

Behind the Scenes with Camera and Lens Testing Service DxO Labs

Stephen Shankland over at CNET has written an interesting behind-the-scenes look at how DxO Labs -- one of the world's premier camera testing services -- evaluates equipment. DxO Labs is based near Paris, France and was the result of a 2003 spinoff from a company called Vision IQ, which specialized in swimming pool safety. Since then, the group has published over 185 in-depth camera reviews on its website DxOMark.

What it Looks Like to Focus a Rangefinder Camera

If you've never used a rangefinder camera before, this video provides a visual look at how focusing works (a Leica M2 is used). Basically you're given a second (smaller) image of the scene, and your goal is turn the focus ring until the two images match up for the subject you'd like to have in focus.
