Understanding the Basic Laws of Light, Part 2

It's so easy to get caught up in the minutia of photography. Sure, megapixels, microcontrast, MTF charts, and the like are all important, but only after you understand how to work with the most important piece of the photographic puzzle: light.

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.

Camera Drone Safety Tips from an Airplane Pilot

I hold a private pilot certificate, as well as a remote pilot certificate; I am also a photographer. I just wanted to share with you some advice from a budding pilot who comes from the much larger world of flying that is general aviation.

The Basics of U.S. Copyright for Photographers

When I was in college, I lived for a while in a crappy little rental house next to a cemetery. Neither I nor my roommate, Brad, knew how to cook anything, and we ate bologna sandwiches pretty much all the time.

Digitizing 9×9 Film with an Automated X-Y Table and a 50MP Canon 5DS R

One of the challenges (and rewards) of managing a digital production lab for a university research library is working with the wide assortment of analog formats that are collected within its archives, special collections, and map library holdings.

Shooting a 300-Megapixel Photo: Film vs Digital

For a recent project, I was tasked with shooting a hot rod. It was exciting from the beginning, because this particular kind of car is pretty rare here where I live. The owner also requested that their dog sit on the car's fender, and for the photos to be huge -- 100 megapixels were too few.

How a Combat Photographer Named a Phenomenon to Honor Soldiers

While embedded with troops in Afghanistan in the late 2000s, war photographer and writer Michael Yon captured numerous photos of the sparkling halo that can appear when a helicopter's rotors hit sand and dust. Upon finding that the particular phenomenon didn't have a name, Yon gave it one that honors two fallen soldiers: the Kopp-Etchells Effect.

How Ansel Adams Wrote Pictorialism Out of Photography History

We all have a blind spot, both literally and metaphorically. Ansel Adams had one so big and powerful that he, Beaumont Newhall, and a few others “disappeared” some very important and wonderful photographers from the history of photography. And in doing so they also helped “disappear” an important movement in photography, one called Pictorialism.

Myths and misconceptions persist because they’re either compelling or no one bothers to correct them. For photographers, many myths of digital photography arose when trying to draw imperfect analogies to film photography.

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.

How Stop-Motion Photography Has Evolved Since 1900

Stop-motion photography has come a long way since the early 1900s, but it still involves creating an animation one frame at a time by introducing slight changes and movements between still photos. To see how far we've come with the technique, check out this 3-minute video, titled "The Evolution of Stop-Motion."
