Is there any concern that ads will use HDR to try to make their ads brighter than the content? The content then will be forced to increase all of their...
`Float16Array` is proposed in TC39 at [Stage 1](https://github.com/tc39/proposals/blob/main/stage-1-proposals.md#:~:text=Float16). Can we move in the direction of advancing that? --- > ### Choice of `Float32Array` for `ImageData` > > There does not...
This issue is to propose that we standardize all conversions to go through the rec2100 reference display (the 1,000 nit one). This way, for converting to/from any of `rec2100-pq`, `rec2100-hlg`,...
In [rec2100-hlg](https://github.com/w3c/ColorWeb-CG/blob/hdr_canvas_r2/hdr_html_canvas_element.md#rec2100-hlg) Suggest to add: The R'G'B' value 0.75, 0.75, 0.75 corresponds to media white (sRGB 1,1,1)
From [rec2100-pq](https://github.com/w3c/ColorWeb-CG/blob/hdr_canvas_r2/hdr_html_canvas_element.md#rec2100-pq) > NOTE: {R', G', B'} are in the range [0, 1], i.e. they are not expressed in cd/m2 Suggest to add: The R'G'B' value 1,1,1 corresponds to a...
three.js recently shipped experimental support for wide-gamut Display P3 color spaces in WebGL.[^1] An issue that has been difficult, in terms of providing a friendly API surface to three.js users,...
Suppose there exists HDR content either as a ITU-R BT.2100 video or ISO 22028-5 image. It has: * Rec2020 primaries * HLG or PQ transfer function * Optional metadata specifying...
In the use cases and examples described by the "Canvas High Dynamic Range" proposal, I'm mostly reading descriptions of how to display existing HDR content, such as images and video....
I interesting about emulation chromaticities or primaries. Can be it done by something way on canvas? What required to do that? Needs or no floating point support? And how emulated...
