Somehow someway my AEB has set itself to -1 and I cant for the life of me figure out how to center it back to zero. I didnt set it there and have no clue how it was changed? Its a canon 40D. Any help would be great guys! Ok, I just figured it out. I had to switch it to a different white balance other than auto and then it let me change it? I guess my question now is why is the camera set to do this?
