How Facebook is Stealing Billions of Video Views

In a Nutshell created this 5-minute video that offers a simple explanation of the problem of "freebooting" on Facebook, when copyrighted videos are ripped from other sources (mostly YouTube) and uploaded to the service without permission.

You Can Use a CD to View the Color Spectrum of Your Light Sources

If you want to view the color spectrum of a light source in your studio, there's actually a super cheap and easy way to do so: an ordinary CD or DVD can do the trick. Simply allow the light to reflect from the surface of the disc into your eye -- it acts as a diffraction grating, allowing you to see the different color bands in the light.

These Before and After Photos Show How Glaciers in the US Are Melting

Over the past several years, the U.S. Geological Survey has been shooting a "Repeat Photography" project in various locations to show how glacier ice has been retreating over the past century.

Why Old Sports Photos Often Have a Blue Haze

Rich Clarkson’s photo of Kareem Abdul-Jabbar, then named Lew Alcindor, in the 1968 NCAA Men’s National Basketball Final Four semifinal game in Los Angeles is a masterpiece of composition, timing, and exposure.
