I use AEB (-2, 0, +2) bracketing on camera and Av to get pics for my HDR test and this does not work more once flash is turned on (has tested with on-camera flash). That's so Canon manual says.
Would someone like to post some experiences how to create HDR with flash(es)?
Is there any way to have AEB worked with flash (on or off camera) to get at least 3 pics for HDR composition?
Or should AEB use only with ambient light, no flash?
Your tips are greatly appreciated.

AEB is not for flash as it only applies to ambient light exposures. If you want to bracket your flash exposures, you need to have a flash that has that feature, such as the 580EX. You can shot up to 3 bracketed flash shots in 1/3 (or 1/2) stop increments.

Thanks Leo.
Yeah, I have two 580EX's and 3 PW's. Could you please be more specific to let me know how to set it up on both camera and flashes?

Set up the flash and camera as you normally would for flash pictures. Then, when you're ready to shoot bracketed frames, push the Select/Set button several times until the bracketd exposure function icon (icon showing three overlapping rectangles) appears and blinks. Then turn the Select Dial to set the exposure increment you want. Push the Select/Set button again to set the flash to bracketed exposure mode. An "Fb-1" will be displayed on the right side of the LCD screen to indicate that you are in that mode. You'll now be able to take three bracketed exposure. Just be sure that the flash has recycled and is ready before each shot. Bracketing will automatically be turned off when the 3 bracketed frames are shot.
