Hi,
I shot a lightbulb today with a half inch steel ball bearing. The still frames I pulled off the camera are quite interesting....

Its quite interesting how the ball drags all the glass fragments with it.
Let me know what you think,
Pete.

Where the hell did you get a high-speed camera? I want one 8)
You should try it with the lightbulb on next time, just use a marble to lessen the risk of tripping the breaker.

Its not a highspeed camera, I wish to god that I had one - I have been after one for years. This is just my broadcast camera on 1/10,000th of a second exposure and lots of light. I used these lights:

They are about 800w each and were very cloes to the subject to keep it well lit.

That's pretty sweet, and I can see that the camera works very well. But how the heck did you get it to shoot at the right time? Or did you just do rapid fire snaps the whole time?

I belive it is a video camera.

Also, if you had the object lit that well and it was still dark, what was your ISO setting? I can usually snap shots on 1/2000 in daylight and they come out brighter than that. Anyhow, just wondering what kind of camera you were using.

Those are 800w redheads, but cheap halogen floodlamps will do it.
You need to flood the subject with light and use the highest exposure you can, i used 1/10,000th /sec

Oh my bad, I read it as 1/1000th. Haha, Now I know why it was dark, ok.

I think air still leaving the barrel pushed the glass more so then the glass trailing the marble.
Heres a test, shoot another light bulb, but this time put 10 feet of distance inbetween the muzzel and light bulb.
Then pull pics from that footage and see what it looks like, and your rite, very interesting.

Next time shoot a lit light bulb
Nice pics, and I agree with jrrdw, the air probaby pushed the fragments along.
