This is something that I h

This is something that I have wondered about for a while now:

Obviously with all the High Def. technology available now, that would be the ultimate choice for the type of project that is being discussed. However is the higher cost really justified? Probably only about 15% of the people who will see my current project have HD capablities; everyone else is stuck with regular ol’ SD. Is it really worth it? Are the HD cameras really superior even if the viewer does not have an HD setup?
