Great shots, did you use a light beam or a sound trigger for the balloon bursting shot?

Canon set to continuous high frame rate, Metz 45 CL-4 digital flash with Quantum Turbo battery set to 1/20,000th of a second with no wait state recycling and a reflector.

Just hang balloons up, set camera firing and use a thin opened out coat hanger with a needle on the end

MUST fill balloons with COLOURED water. Experimented with food colourings, BLOE and RED work best, use good quantity of colouring.

For the strawberry same setup with flash pointing down in a fish tank

If you consider that a balloon bursts at about 1/5000th of a second then shooting as I do at 1/8000th of a second with HSS flash (sorry didn't mention that earlier, you NEED HSS and shoot at 1/5000th to 1/8000th) then shooting at 6fps you are guaranteed to get one good shot in five belloons.

Very interesting. Low power flash of course reduces the flash duration and stops action better. The closer you get the flash to the subject whilst still out of shot if using TTL flash metering the shorter and hence faster the action stopping flash pulse will be.

In essence then you are popping the balloon during what amounts to a low speed video sequence and then selecting appropriate frames from it. Once the motordrive was introduced to cameras the distinction between stills and video photography gradually disappeared when using it as motordrive speeds increased, as we see now with cameras incorporating video, which is basically just a continuous motordrive sequence. The only difference being how the end result is displayed, either as a continuous moving image, or a series of stills from it. Though motordrive sequences at 6fps have yet to catch up with video, but are as yet of much better resolution per frame:-

"Both camcorders and some video capable digital cameras offer not only the ability to select resolution such as 640x480, 1280x720, or 1920x1080 but also offer the ability to select from one of a number of frame rates such as 24, 25, 30 or even 60 frames or "fields" per second."

I think we are inevitably moving to the video and stills cameras merging, where stills will simply be taken from video sequences once the video sensors are of sufficient quality for stills work and a rotating shutter replaces the present stills type one.

Very good shots Jeremy and an innovative and interesting way of moving away from conventional flash triggers usually used for such stop action results.
