@ahab1372: It's set to ETTL.

@Mark: Okay, that is what I'm expecting. I just thought it was "illustrated" by the exposure showing dead center, i.e., to indicate it will compensate for my settings. I did a few more experiments after I started the thread and some of those shots looked to be properly exposed. It's starting to lean towards poor memory. Now, to go over 1/250s, I need to switch to high-speed sync, correct?

Thanks for the responses, guys!
