there is another way:
you have to set an option in the custom menu first:
on the k20d its item nr26 (green button in TAv & M).
if you set the value to 2 (Tv shift), you can use M mode, set exposure (aperture and shutter) manually and do a bracket.
the camera will then only change the shutter value whilst bracketing and will always use the same shutter values on the next brackets.
this way you get consistent exposure on all brackets you do.
hope this is what you are looking for.
