Flash and burst mode

How do you use flash to capture rapid sequence of action when camera is at burst mode, say 8 frame per second?

Put flash on very low power setting.

Also use very high ISO and as wide an aperture as possible for the shots you're taking. And an external battery pack helps, too. Just don't overdo the bursts and burn out the flash.

Thanks. That is what I want.
What is the best rate of frame per second you can achieve in studio?
Any suggestion on best strobe or speedlite made especially for this purpose of rapid shooting?

I can't see why you would need to shoot in bursts in a studio unless the model is dynamic and moving around a lot or you are having a difficult time getting the model/subject to give you the expression you want on his/her face.

But to answer your question, whatever frame rate your camera can do would be possible in the studio as long as the camera and the flash power level is set appropriately. Faster frame rates might be more difficult to achieve with studio strobes, though, compared to using hotshoe flashes. For example, you might be able to do a short burst of 8 fps using a flash but only manage 2 or 3 fps using a strobe.

I would guess you need to use more lights, and have less power, with higher ISO and wider Aperture (as mentioned above)

in a dark room with a single bounced flash, I can generally get at least 5 bursts (the camera bursts at 3.4/ second, not 8....), and that's with my stofen attached.

Canon has very explicit instructions about using their flash units, even at fractional power settings or stroboscopic mode, before stopping to let it cool. Since so many users failed to read or to heed the instructions, resulting in burned out flashes, Canon engineered the 580EXII to intentionally limit foolish photographers rather than allow itself to be burned up through negligence.

Sometimes you can achieve a similar effect by using the stoboscopic function of the flash.

Not sure I follow. What effect would that be? And how would that allow the shooter to shoot at a fast frame rate? Or are you suggesting that the stroboscopic rate can be adjusted so that it flashes at the same rate as the frames are shot?

here's a vid of chase jarvis that i found interesting
he shot at 8fps and got flash on everyone, he shot at 60% power.

If you plan on using gels, be careful. Try not to fire too many shots without giving it a break. The flash gets VERY hot after repeated use, and gels and begin to warp and even melt down.

I had a double layered green gel warp out of shape after just 2 or 3 flashes yesterday.
