[edit]
Ugh... I really can't believe this but somehow you got under my skin and so I have to reply to this where I really should just laugh and move on.
I was trying
not to credential myself, but fine... I've been a photographer for about 10 years, about 8 years professionally. I use and sell HDRs as part of my portfolio... both professionally and artistically, though it is not something I do frequently because it is not necessary in most circumstances for what either I or my customers need.
I have rather pointedly researched this AEB thing, much like everything in photography I have learned. That is through speaking with quite a few professionals, and even speaking with a couple photography professors. Oh and yes, I googled. However, I consider google to be a little less authoritative than seasoned professionals, since the internet is full of all kinds of people doing some fairly crazy things.
Oh... and I also researched it in my own camera manuals.
Bracketing
The D100 offers three types of bracketing: exposure bracketing, flash bracketing,
and white balance bracketing. In exposure bracketing, the camera
varies exposure compensation with each shot, while in the case of flash bracketing,flash exposure compensation (flash level; 102) is varied with each shot. In both cases, only one photograph is produced each time the shutterrelease button is pressed. Several shots (from two to three) are therefore required to complete the bracketing sequence. Exposure compensation and flash bracketing are recommended in situations in which you find it difficult to set exposure and yet do not have time to check the results and adjust settings with each shot.
In white balance bracketing, the camera creates multiple images each time the shutter is released, each with a different white balance adjustment (50). Only one shot is required to complete the bracketing sequence. White balance bracketing is recommended when shooting under mixed lighting or when you want to experiment with different white balance settings. White balance bracketing is not available at image qualities of NEF (Raw) or Comp. NEF (Raw).
The D300 manual said the same thing, as did the D3 manual. I suppose Canon might say something different, but I'm not going to go download it.
AEB was not intended for HDR. It was created to allow you to take a few shots quickly to ensure you had the right exposure of the scene in question. It's a CYA feature.
Can it be used for HDR? Sure. However, the really good photographers I know poo-poo it because it takes control out of their hands, and generally I find that better photographers used automated features less. I poo-poo it for the same reason. It just doesn't buy me anything, and in some cases it doesn't work as well as if I do it by hand.
Think of it this way... you can use a screwdriver to bang in a nail, but that doesn't mean it was intended for that purpose. Or more appropriately, in this case... you can use a ROCK to bang in a nail...
Do you have cause to be displeased at Canon for limiting something you use? I suppose so. I can't outright say you're wrong, because hey... maybe that rock you are using is very effective, or fits your hand a bit better than a hammer... and hey... Van Gogh was considered a hack in his time. Maybe you're the next one. Who knows. However, your position that they are gimping serious HDR photographers everywhere is an opinion like everyone else's, and as an experienced photographer I can tell you that your opinion is not widely shared with folks who I have found to be successful in this space.
