I have a Canon T1i and wanted to take some pictures and then use HDR software. The booklet tells how to auto bracket the aperture. However, I want to maintain the same f stop so I will have the same depth of field and bracket the shutter speed. Does anyone have any suggestion on how to do this. Thanks

So far as I know, the Auto Exposure Bracketing system on our Canon does just that - it maintains the same aperture setting and alters the shutter speed. At least when I use mine, (rarely) I hear three different shutter speed actuations. Set -1, 0, and +1 and fire away.

Thanks, I might have misread the book.

Most HDR shooters use 5 settings -2, -1, 0, +1, +2 have fun and I hope you have lots of extra time, its addictive.

fstop is the aperture. just a shorthand word .

Very easy. Set your camera to Aperture Exposure mode (Av on Canon, A on Nikon) and AEB. The camera will change the shutter speed for each exposure automatically leaving the aperture at the set value.

You are correct in that you do not want the aperture changing in a AEB mode.

Yes, I forgot to say that using AV mode and AEB go hand in hand. Good point.
