The best thing since sliced bread…
The µ-Trigger is a small device that allows the photographer to enter areas that have been difficult before: very long time-lapse photography, triggering the shutter or flash unit on the occurrence of sound or light events. Even bracketed series of (very long) exposures to capture exceptional HDR scenes. The device can mount to the camera, connects to the camera shutter cable input and to the flash unit. There is even an extra input that allows connecting the device to your other (home built) sensor electronics.
The device has an internal battery that lasts for days of intensive use and that can be charged via a mini-USB connector.
This device truly expands your creativity!
