Your Guide to the Digital TV Conversion

Broadcasters expect to be ready, but your old faithful antenna might not be. Here's what you can do to avoid sitting in the dark next year

An article in last weeks New York Times must have struck terror into the hearts of readers whose old tube televisions sport rabbit-ear antennas. The punchline: Many of them will be staring at a black screen after next years transition from analog to digital television broadcasts—even if they purchased a government-subsidized converter box. And broadcasters are to blame.

The real story, though, is more complicated and harder to predict. So what will happen to your television on February 18, 2009?

Build a Backyard Theater

Construct a high-def front projector for hundreds less than store-bought models

Want some real home theater bragging rights? Instead of buying a projector capable of casting a 14-foot image at 1080p (progressive) resolution-the highest high-definition there is-build one yourself. After all, the front projector´s innards are simple: an LCD lit by a superbright lamp, and a few lenses to magnify and sharpen the image. Retail models start at around $800 and use proprietary $400 lamps that burn out every few years. But cheaper lamps work equally well, and none of the other parts are very expensive. Why not put one together yourself?

Shaken, Not Blurred

The newest pocket cams use stabilization to save you from your shaky hands

The smaller your camera, the more susceptible it is to even the slightest tremble, which can leave your photos looking like Impressionist paintings. Fortunately, optical image stabilization has trickled down from pro cams to the shake-prone pocket models. The cameras use motion sensors to detect any quiver and move a piece of the lens to compensate for it. I tested three in the most blur-inducing scenarios: in low light without a flash-the slow shutter speed gives you more time to twitch-and at full zoom, which magnifies shake.

Can Digital Photos Be Trusted?

The web is crawling with jokes, hoaxes and more insidious fakes. Digital-image experts aim to develop foolproof detection tools, but until then, seeing is not believing

Lance Corporal Ted "JOEY" Boudreaux Jr. was bored. It was the summer of 2003 in Iraq, the pause between the heavy lifting of the U.S. invasion and the turmoil of the insurgency, and you can joyride around the desert in a dusty Humvee only so often. Loitering at the back gate of his base, mingling with locals, Boudreaux says he scribbled "Welcome Marines" on a piece of cardboard and gave it to some kids, who then posed with him, smiling, for a snapshot. He e-mailed the picture to his mom, a cousin and a few friends, and he didn´t think about it again. Boredom moved on.
