News: Revolutionary "Light Field Camera" Lets You Focus After the Picture Is Taken

Focusing has always been a problem with photographers, and even with today's digital cameras it's not easy. The most obvious problem is trying to accurately focus on the subject before exposure. Next, you have to choose the correct aperture size in relation to the depth of field, and make sure you're using the correct exposure. Then there's lens aberrations, where a certain ray of light does not converge to a single focal point in the desired image, resulting in some light leaking away from t...

How To: Easy DSLR Project—Get Unfocused!

(Difficulty Level: from Newby to Expert) Digital cameras can produce freaky sharp images—it’s one thing that sets them apart from film cameras. A DSLR doesn’t have grain, it has noise—and that sounds a lot less charming for a reason.

How To: Teaching Nerds How NOT to Love with Silver Dollar Games

I am the sort of man whom game companies fall all over themselves to seduce. I'm sweaty, pale, awkward, and spend too much money on video games. There are many of us, especially among XBox 360 owners. We are the most stereotypically "gamer" group of console owners. The XBox 360 doesn't have motion control like the Wii or a blu-ray player like the Playstation 3. It just plays games really well. That's why hardcore gamers like me prefer it amongst all the consoles, and probably why Silver Dolla...

Listen In: Live Social Engineering Phone Calls with Professional Social Engineers (Final Session)

We had a blast during last week's social engineering calls. One of our attending social engineers was so clever that she convinced several people on Craigslist that lost items were hers, even if it seemed she couldn't be trusted. But females are better social engineers, naturally. Some say that females have a special knack for manipulating men, but I think that's preposterous. I can't see why that would be true in a million years (note my sarcasm).
