This way you can take pictures of water droplets (say) and get the timing dead on for different stages of the splash. The main problem is dealing with shutter lag. For something like a balloon popping, it will have popped in oh.. 100 microseconds easily. Even a D3 has a few milliseconds lag so the only realistic way to take pictures of very fast stuff is to leave the shutter open and trigger a flash instead.

The next model i'm working on will be able to trigger either cameras or flashes (via PC cables) to make this easier.]]>Feb 8th 2010 6:08PMhttp://www.engadget.com/2010/02/08/diy-photog-creates-laser-trigger-for-remote-dslr-snapping/http://www.engadget.com/2010/02/08/diy-photog-creates-laser-trigger-for-remote-dslr-snapping/
If you shoot at 1/1000 you will maybe still have some streaking meaning that you need:
1- CRAZY BRIGHT LIGHTS
or
1-DARK ROOM
2-BULB MODE
3-FLASH GUN

The flash gun method is the best because the bulb means the camera is constantly taking the picture but because it's all dark you can get the flash to freeze the frame since Flashes are WAY faster than most shutters.
So all you need is something to trigger the flash which is where this laser could be used to trigger it instead of the shutter ;)]]>Feb 8th 2010 9:40PMhttp://www.engadget.com/2010/02/08/diy-photog-creates-laser-trigger-for-remote-dslr-snapping/http://www.engadget.com/2010/02/08/diy-photog-creates-laser-trigger-for-remote-dslr-snapping/Feb 8th 2010 4:57PMhttp://www.engadget.com/2010/02/08/diy-photog-creates-laser-trigger-for-remote-dslr-snapping/http://www.engadget.com/2010/02/08/diy-photog-creates-laser-trigger-for-remote-dslr-snapping/Feb 8th 2010 5:01PMhttp://www.engadget.com/2010/02/08/diy-photog-creates-laser-trigger-for-remote-dslr-snapping/http://www.engadget.com/2010/02/08/diy-photog-creates-laser-trigger-for-remote-dslr-snapping/
Both myself and another interweb user developed similar projects for an Instructables competition (both were featured on hackaday too). Mine was a sort of all-out camera controller (for SLRs), his was a very simple but very effective laser trigger that worked on canon compacts.
