Thats a pretty cool project, and I have couple of questions.
When triggering the shutter, do you hold it open and trigger the strobe separately or do you actually have it timed to the shutter release with both being controlled by the mcu?
Were you able to find plug sockets for the shutter release for your camera or did you make one up?
Nice pics btw, this makes me want to take apart a sub woofer I have and experiment with something like this.
I have seen these and i am I have seen these and i am do not know if i just do not understand cameras or what. But how is it triggered to take a picture, as in how does it actually make the camera snap a picture? i see that it triggers the flash but does it not also trigger the picture taking button ?
I was curious of the same thing. I know that most slr cameras have a remote shutter release cable and have considered hacking a cheap one to trigger the shutter as it’s pretty much a button switch.
I’m afraid that it would I’m afraid that it would be a boring video. The photos are taken in a dark room and the flash is only on 1/20.000 sec J<o:p></o:p>
