Colorist Robbie Carman enlists the help of two experts to explain the evolving technology of high dynamic range.
He writes on Mixing Light, "While that’s simplifying things drastically (especially on the math side) HDR video is all about the expanded dynamic range capabilities of an HDR display. Instead of being limited to the typical 100 nits/29fL of an SDR reference display, HDR displays can display 300, 500, 1000 and even 3k, 4k nits! One day, displays capable of 10k nits are expected, but currently need a power station built for a small city to work! The thing about an HDR display is that peak brightness is not for the entire screen, but rather for a small portion – with 10% being common. So HDR while being about expanded dynamic range, really shines in how it handles bright highlights."
