Best Way to Vent a Shower

A while ago I read somewhere that enclosed showers with high (9'-0") ceilings are best ventilated thru the wall rather than at the ceiling, to capture steam at 8' before it has a chance to condense at 9'. Is this correct? We're at the point of making bathroom ventilation decisions for our new construction 3x4' showers and wd appreciate any feedback on the best (and most comfortable) way to handle shower venting.

Thanks! --Mark
