Design News shows you how to make a “slave strobe” for your camera -

“Photography enthusiast Nick Pagazani was hindered by the range and fixed location of his camera’s flash. Since his camera has no connector for an external flash, he needed a light-activated slave trigger to fire a remote strobe. It had to ignore the pre-flashes used for red-eye correction and fire only on the main flash. His solution: Use a microcontroller to count pulses from a phototransistor and trigger the strobe at a switch-selectable count. Brighten up your shadowy background with this flashy accessory.”Link.

    Cool stuff, but I wish he’d mentioned how much the parts cost.

    To fix the range and location issues, an easy way to slave other flashes is through IR. You can turn your built-in flash into an IR signaller by putting an undeveloped piece of slide film in front of it.
