Digital Rebel auto bracketing. Does it work well.

Hi guys,

Please exuse me if this has been covered some were already but I have not found it and my time is running short. I probably should have posted this on the begginer forum but I was trying to get a little more specific.

I am new to both underwater and topside photography but I have been dabbling with this camera for about six months on the surface. More technology than brains I guess.

Is the the digital rebel auto bracketing worth the time or should I step up and down myself? How much span should I set?

I am off to Cozumel on sunday so any basic help on everything would be much appreciated. I have read a few books but I know you guys have a lot of tricks and ideas that might help me out.

Thanks for your time, and I hope to have some photos up soon for you advise.

Oh by the way, this is for my companies new catalog so cross you fingers for a newbie who is probably going to have a very blurry catalog.

Cheers

Mike :? :?
