I'm not sure, but it's interesting.we should have more thread like this.

JJ, Did you change your remark? My email had additioanl commentary: "


I'm not sure, I see the same dot in picture 2, maybe the bullet was hitting that dot?"


I am guessing you see the dot[].





Anyway---thanks for posting.

yes, I edited my post after I found that out, those were 2 same pictures, sorry! and I tend to agree that was a bullet now.

Looks like a UFO to me.





Nice photo and timing.

After reading the title of this thread, I thought you had literally shot the poor 7D... Maybe I need some sleep. I agree with the above though, maybe try to get a clearer shot of the bullet the next time you can do this.

wow.......great shots......and whoever the shooter is - what an amazing shot he is[:O]......he hit that insect in frame two with one shot....notice in frame 3, the insect is no longer there? [:P] lol.......just kidding [] i also like frame 4, catching the ejected casing

Ok, Just to put this in perspective: Assuming the bullet travels at 1450 feet per second and the shutter speed is 1/8000 of a second---I calculate that a half inch bullet travels at 2.1 inches while the shutter is open. The 7d, at best, will only deliver a 2.1 inch blur of a 1/2 inch object----Now if I had the skill to time a flash at precisely the right moment, Then maybeI could capture a frozen bullet in the air----But I just ain't that good.


Where are the engineers and math whizzes----are my assumptions and calculations correct? What does it take to capture a frozen bullet ?


Just a drill,


Bob.


P.S. Is lightning this difficult?

Triggering the strobes with a circuit that detects the gunshot, and adjusting the flash positions until you find the sweet spot could work. Remember 1/8000th is actually a stroboscopic flash as the second curtain has to chase the first requiring the flash to sync to each segment of the exposed sensor.


I have a setup with 3 580exII's on a single light stand that should work.


BTW - I'm saving for the radiopopper PX system as I want at least 1/500th sync speed. This will cost a bit with 4 flashes, but I've come this far! -Shea
