I have received numerous inquires as to what is a Hi-Def virtual tour and what makes it so special. I have been doing tours since 1998 beginiing with Ipix. Early tours took almost a minute to load and the images had most of the resolution sucked out of them in order to load. The Hi-Def platform that I began using in the past year does not alter resolution. These are raw camera images that open to the size of your monitor. That is a dramatic improvement over previous technology and makes evaluating Real Estate online an unbelievable experience!
