I do not get it. I took two pictures, one at 1/320 and the other at 1/20 with the same aperture. The pics look basically the same. Why isn't one of the exposures much different than the other?

Duh. Manual flash mode in the Custom Settings menu.
I do not know how I missed that before.

This is an old thread from 2008. But, I'll reply anyway to let you know why the exposure was the same, even though your shutter speed was very different between those two captures.

Shutter speed has no bearing on the amount of light from the flash your camera sees (unless you try to use a shutter speed that's faster than the sync speed). That's because the flash burst is very short (usually around 1/1000 to 1/10000 second, depending on your distance to subject).

So, as long as you don't have enough ambient light to expose your subject (and you can use shutter speed to help control how much ambient light gets through for a given aperture and ISO speed), the exposure may look identical using very different shutter speeds with flash when you have the same settings for aperture and ISO speed, even if you're using the same manual power settings for the flash.
