If you think schlepping a tripod along with your DSLR isn't worth it because you're convinced you can get a clean shot if you just concentrate hard enough, we have to ask... how's that working out for ya? To demonstrate the destructive power of shaky hands, Camera Technica attached a laser to the hotshoe of a Canon 7D, with the light reflecting off a wall 20 feet away. The lesson: it's challenging enough to get a crisp shot with a tripod -- let alone without. In the video below, the laser point wobbles erratically when the photographer gingerly presses the shutter with his finger. In the second clip he uses a remote release, which visibly cuts, but doesn't eliminate, the shake. Only when he locks up the mirror and resorts to a remote release does the shaking drop to a minimum. Need some more vivid evidence? We highly suggest heading past the break for a demo that might just make you reconsider that decision not to pack aGorillapod.
As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg
