I really wish I’d had this handy Widescreen vs Pan-n-Scan (“Fullscreen”) video back in the day when I worked at a video store. It was often so difficult to explain to people why fullscreen was anything but full and how widescreen did not, in fact, cut anything off.
I remember having to explain to the older demographic this idea when I worked at Best Buy. It took me making sign rails and endcap posters with visual examples to drive the point home.
Still, there’s no convincing some people. “I don’t like those bars… the’re SO distracting.”
