Yep. Or a slower shutter speed would have done the
same thing.

Chris posted a nice example of how, when doing
wide-angle, you have to juggle the ambiant light
exposure of the back ground and the flash exposure
of the foreground so that they are the same. In
this case , note that the strobes were in TTL mode,
and with the larger aperture (f/2.8) they undoubtedly
put out a lot less power. It would have been really
cool if Chris had also shot one at f/2.8 with no
strobe to show the background with just ambiant
light.

This concept of juggling the two exposures is one
of the most difficult to get your brain around,
but once you do, it becomes almost automatic, at
least above 100'. Below 100', my brain turns to
mush and photography gets more difficult.
