Kevin Shaw on HDR for Filmmakers

HDR on Wetpixel

FinalColor has posted an article entitled “HDR-An Introduction” by Kevin Shaw. In it, Shaw describes the use of HDR displays, the move from a Gamma based standard to perceptual quantization (PQ) electro-optical transfer function (EOTF). He points out that 4K resolution is a 400% increase in data for (once compressions has taken place) relative little gain, whereas HDR is a 20% data increase for a “huge” improvement.

So what does this latest change mean? The importance of HDR is often likened to the introduction of HD, but actually the shift from black and white to color is a closer analogy.
