Stradawhovious said:Shutter speed has nothing to do with it. Even at 1/8,000 you wouldn't have any luck at all. It's all about the light.
I have tried with normal speedlights..... Nikon B-600, SB-25, SB-28 etc, and none of them, even at their lowers power settings (shortest flash duration) are fast enough to even begin to capture a bullet in flight. That would translate to about 1/30,000th of a second burst of light.
I've circled the bullet here......
This was with a sub sonic .22 out of a handgun. The bullet speed on this was less than 500fps. If you are shooting anything of a harder caliber than that, it will be moving MUCH faster. .45 will be 800-900fps, 9mm will be moving 1,000fps or so etc. If ou get into rifle country, a pill from a .30-06 will be moving close to 3,000fps.... so you can see the issue here.
Unless you have absolutely no ambient light, and a flash capable of over 1/100,000th of a second burst of light ($3,500+ microflash), I say you don't stand a chance. Sorry!
You just said shutter speed has nothing to do with it, and then said that you would need a speedlight with 1/30,000 burst speed to capture it... Which would still require a shutter fast enough to capture it.
So, please elaborate how shutter has nothing to do with it?
Shutter speed only has to be wide enough to capture the burst of light... and sync with it. You may have notice that max sync speed on good bodies is at 1/250? (unless you go into High Speed Sync). If you shutter is open for 1/100, and the flash with a 1/30,000 duration goes off somewhere in the 1/100 of a second, you caught the flash. Get it? Shutter speed will capture Ambient light... so you can control ambient exposure and backgounds with shutter speed. For high speed photography, you want to minimize any ambient light exposure, as it will cause blur
Aperture is more important when using flash.. it determines how much flash hits the sensor!
EDIT: hahaha.. should have read further down.. already been said! I was hoping Strad would see this thread, since he has been playing with high speed photography lately.
