In concert photography, where light is at a minimum, the capturing of images is tough. But sometimes, bright lights flood the stage in often seemingly random intervals and for brief periods of time. I’m not talking strobes, but spot lights that come on and then go off again in matter of 1 second. Enough time for me (the photog) to realize there’s lots of light, but by the time I push the shutter, the light is gone.

Yes I realize that training the photographer is simpler and cheaper, but I’m a geek that like to build shit.

Build some sort of device that triggers the camera to take a photo which when turned on will focus and snap a photo based on light levels passing a certain threshold. The light sensitive are should be directional. I don’t want it going off just because buddy’s flash went off 3 feet from me.
