Fake HDR Footage on DSLR

So I really wanted to know what gives a cinema grade movie that 'movie' like feel when you watch it, is it the colouring? The camera it's self? I'm sure it's a combination of many different things but I stumbled across HDR while researching. Now I have heard of this for normal pictures but not really for film, it turns out that higher quality cameras have a better dynamic range than your lower end ones.

What is High Dynamic Range? (HDR). Basically the higher dynamic range your camera has the more the lights and dark it can handle in one go, have you ever noticed when you focus your camera on a wall near a window, the window it usually totally white. Where as if you point it to the window it adjusts the light outside and your walls become really dark. A high grade camera can create both of these scenes at the same time, giving what realistically your eyes see and ultimately a real look to your film.

Now with my camera (Canon 550D) and many others there is a firmware hack called 'Magic Lantern' which can grant you many more high end features than what you'd usually get. One is the 'HDR Mode' which essentially flicks between ISO 100 and 3600 while recording to a darkened image for your lights and a brightened image for your darks. You can then take a nifty piece of software which will merge your two frames together so you're left with fake HDR footage. The only limitation is that you have to limit your subject movement or you will get a ghosting effect.

I found this idea while searching on YouTube from a group called Neumannfilms. They have about four videos on HDR footage and one is a workflow video here.
