I am trying to create an HDR image using my speedlite 430ex and canon rebel xti , but when I set the exposure comp. and press the button, it just takes one exposure. I'm thinking because with flash, it'l be the same brightness because I'm using flash.
But, ive see others' pictures of people that used flash create an HDR. So how do I do this? (and I don't want to do a faux-HDR, I want to use 3 real exposures)

Thanks!

Set flash exposure bracketing, not camera exposure bracketing.
You can't combine the two, so you have to make sure the flash is dominant.

I see, thanks a lot

Terminology? I don't think there is a 'flash exposure bracketing'. There is an exposure bracketing.

Not sure what exactly you are trying to do but HDR is for high dynamic range images - where the sensor on the camera can't get it all in one exposure.

Sure there is, Dave. FEB. But it's set on the flash, not the body. :)

Ok - I couldn't find it in my 430EX manual. Live and learn.

I did find it in the 580EX manual.

Hmmm, yes, live and learn and that applies to me as well. I did not know that the 430EX does not have FEB.

I wanted to re-create this:

The very first image looks like HDR to me.

I was able to pull off creating a "faux" HDR using one image and it worked alright - I'll still see if I can do something else though.

That look might just have been created via post processing and not via multiple flash or strobe exposures. Those pictures were shot with AB strobes so if flash exposure was varied, it was done manually and the subjects would have had to stand still while the photographer was making the adjustments of the strobe power level.

Have you seen the following post? Might be worth PMing the photographer if you're interested in learning more about how he created that image.
