Today’s cameras are able to capture an enormousness amount of dynamic rage. Sadly our monitors and film projectors are not able to display the entire tone range that we can capture. This calls for a process called Tone Mapping. This process squeezes the larger, captured, tonal range into a smaller tonal range that the display is able to display. It is the same process that gives HDR its signature look. Of course if not done subtly, it can create a
chewed to death overwhelming effect.
When video comes into play, HDR tone mapping becomes even harder and can result in some interesting video artifacts such as ghosting, Brightness Flickering and camera noise.
The team at Disney Research (yes they do research as well) created a new algorithm that can better handle the tone mapping part of HDR processing.
