This page says that Tv mode is for aperture priority but that is incorrect. A camera dial may have "A" and "S" for aperture and shutter priority modes, respectively, or "Av" and "Tv" for the same modes. One of my previous camera manuals described these modes as "aperture value" and "time value," respectively. A quick Internet search turns up the same information.
