“How’s the image quality on the TriPod 5?” That’s a question you would perhaps be hearing these days if certain decisions had been made differently years ago over in Apple HQ. When the Cupertino-based company was brainstorming names for the smartphone that would eventually be called the “iPhone,” one of the names that was being considered was “TriPod.”

In in 1946, the United States conducted a series of nuclear weapon tests at Bikini Atoll in what’s known as Operation Crossroads. A total of two bombs were detonated to test the effects nuclear blasts had on naval warships. The second, named Baker, was the world’s first nuke to be detonated underwater. Due to the unique properties of underwater explosions, the Baker test produced a number of unique photographs that the world had never seen before.

Canon released a new firmware update for the 1D X this morning that gives the DSLR cross-type autofocus when using certain telephoto and extender combos that have a max aperture of f/8. The announcement page includes a list of lens/extender combinations that are now compatible.

The first lens listed in the 1.4x Extender column is the “Canon EF 70-300mm f/4.5-5.6L IS USM.” Problem is, that’s not a lens that exists…

This is probably a “duh” fact for many of you, but one that some of you have perhaps never heard or realized before: Did you know that the flashes in the Canon Speedlite lineup are named after their maximum guide numbers? To figure out the power of your Speedlite, just take the model name and hack off the zero at the end to get the GN (e.g. 430EX has GN 43, 580EX has GN 58).

Have you ever wondered why computers always indicate that your hard drive or memory card has a smaller storage capacity than what’s advertised on the box (and the card itself)? No, it’s not because you got a defective card, it’s not because your card came preloaded with a bunch of unwanted files (your hard drives, maybe), and it’s not because the manufacturers are cheating you by skimping out on the storage space (well, not directly, at least). The reason has to do with math and marketing.

Did you know that there’s US currency on Mars? It’s true: when NASA’s Curiosity rover was launched back on November 26, 2011, one of the things it carried with it was a penny from over a century ago. The 1909 Lincoln cent is part of the rover’s onboard calibration target used to check that the cameras are working properly.

You know the infinitely long tunnel that appears when you look into two mirrors that are pointed at one another? Have you ever noticed that the tunnel becomes more and more green, the deeper you go?

YouTube personality Vsauce has a fascinating new video titled “What Color Is A Mirror?”. In it, Mr. Sauce explains that this is due to the fact that there is no such thing as a perfect mirror (i.e. a mirror that perfectly reflects 100% of light). The fact is, a typical mirror best reflects light in the 510nm range, which we perceive as green light.
