Proof that good ideas are expensive, the Japanese "creatives" known simply as Party rounded up 250 Canon 60D DSLR cameras with flashes, hooked them all up to arduino circuit boards and used a computer to synchronize them — all just to create a music video for a Japanese rock band.

Alone, each Canon 60D costs $1,400 with a kit lens. With the add-on flash, that price goes up. At a minimum, we're looking at over $350,000 worth of DSLRs (without flash) alone. That's quite an expensive music video effect.

Made for Japanese rock band Androp's "Bright Siren" single, the entire project took over 48 hours to shoot, 20 volunteers to help solder the "bullet boards with the camera and PC" and a whole lot of "running around Tokyo collecting rental cameras and strobes."

It was so challenging that the Party creatives didn't even get to test the rig until the day of the shoot, which meant it was "do or die" scenario. Luckily, it all came together. And thankfully, nobody was blinded in the process.

Photogs will enjoy the music video and behind-the-scenes (hit the FastCompany link below), even if the music somewhat soft for a rock song. Now, if only they had added some color filters over the flashes, then the video would have impressed us.
