This whole thing is screwy, Jeff
Because the shadow is cast to the left, and not significantly below the item, you won't see it.
Look at the top of the stool, the shadow is almost directly in line with it.
Because of the distance this was taken from, and the closeness of the flash to the lens, the shadows aren't large at all.

Red-eye would normally be a serious problem with the flash this close to the lens ... if the pre-flash and red-eye prevention wasn't so good.

With a typical on-camera additional flash, the shadows would be more pronounced. If the shot had been taken from closer, the shadows would be wider.

I wish I had a full resolution version of this to show it clearly.
