Thanks for the cool site but the "White Balance" setting was the problem.

There is an example on that page that has three shots of a man and woman at
different exposure and aperature. The three shots look like they were taken
at the same time--the couple seems to be in exactly the same position, with
no movement at all.

How is this done? I'd expect to see some slight movement between shots
while the photographer changed the settings.

Those images simply illustrate what the author is trying to describe. It
could easily be one photo with the bg manipulated. Probably is, as the
"motion" in the first frame is too uniformly blurred across the two
subjects.
