HDR tech is very useful in my line of work, 3d rendering... we use it for arch viz stuff all the time. mostly to aid in creating realistic lighting and exposure in 3d simulation.

they are actually working on HDR monitors that can display MASSIVE contrast ratios, which should be intersting

Currently whats demonstrated above is essentially a hack to compress the true dynamics into something that can be displayed on our crappy tech, and although it looks great, and better than an single photo could look, its not even close to how it should be.
