    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.

    Re: 7D can Catch a Bullet



    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

    Cool shots Bob!


    Perhaps it's an idea to shoot some video with high shutterspeeds? And then do some print-screening []Dunno, but it might work...


    Have fun out there!

    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?[img]/emoticons/emotion-8.gif[/img]"


    I am guessing you see the dot[img]/emoticons/emotion-5.gif[/img].





    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.
