I think you have started something Lello we will all be having a go.:D:D

Shame we all live so far away from each other! if we were closer we could have shared the Sound Trigger (at least trying mine out to see what it's like)
with a view to either making one or buying one :)

Thanks for the explanation Lello. I'd guessed that you'd need to use bulb and flash, but couldn't figure out how to synch it all up. The sound trigger is a great idea. I too find the water filled shots to be fascinating. Keep up the good work.

Here are some shots of the built sound trigger, The shots show it in a large matchbox,mainly to protect it and for ease of carrying around.
You can also see that I have spliced the trigger wires on to an old PC cord.
The yellow Ponentiometer (switch) is to control the sound coming from the Mic, and the blue switch is for delaying the flash.

If there was a section for the best post on the forum I think this should be in it!....great Lello, and inspiration

Interesting a mention of a bullet hitting a balloon was made......way back when, the A'level Physics text book had a photo of such. Was fasinated by it and remember it well (that and a london bus on top of 4x unbroken glasses, but that's another story)was made using a specially adapted Nikon, and IR light trigger, due to sound travel being so much slower in the field.

The reason I mentioned the bullet was that years ago there was a picture taken from the side of a bullet caught in mid flight having just neatly cut in half an edge on playing card. This was in pre digital days so have no real idea how it was done. If genuine it would need a very special high speed flash to freeze the action and probably a high speed cine camera too. Anybody else remember the picture?

This one is fairly well known.......

Must have used a lot of film up, and apples, before they got it right.

Thanks Joe,
Most appreciated,
Now that I have the sound Trigger I'm looking for things to use, I'm trying to get hold of a BB gun (ball bearing gun) or an air gun to try and shoot a light bulb!
maybe a golf ball being struck by a club! Party popper, any other ideas? bring them on :D:D
