Mike Seymour test drives HDRx on the RED Epic

We already talked about the HDRx mode of the new RED EPIC camera here and here.

Now fxphd dean Mike Seymour received a pre-release model that most digital filmmakers would kill for, and the first thing he did was to strap that puppy to the hood of a car and race it around town. Famed DV Rebel Stu Maschwitz was also involved, so that might as well be his brilliant idea.

And here's the footage they got out of it: No remote controlled exposure adjustments, no visual effects, just some sensible grading of the HDRx material to show off all the dynamic range captured.

So, how does that work? When put in HDRx mode, the RED camera will capture two exposures for each frame, and lay them down as A Track (hero exposure) and X Track (highlight details). It does that by using a double-readout method. Shortly after the shutter opens, it will read the X track, then wait a bit (without resetting the sensor), and then read the actual hero exposure. Pretty clever.
