I'm excited for new displays where instead of RGB primaries that can only show a triangular subset of possible colours, we have dynamic primaries that can combine to show almost any colour.
- travisjungroth 6mo agoI want all the colors! Give me the full spectral power distribution!
- madaxe_again 6mo agoPromptly cooks in the microwave and infrared, and fries in X-ray and gamma radiation Ahh true HDR
- smallerize 6mo agoThat sounds cool but how do you encode the image data?
- zh3 6mo agoJust save pixel values as wavelength rather than RGB?
- ledoge 6mo agoThat's the easy part, just use a color space with imaginary primaries (see e.g. ProPhoto RGB), or use one with real primaries that allows for negative values – e.g. Windows uses floating point scRGB for HDR, which is just linear BT.709/sRGB, but negative RGB values can be used to cover the full range of real and imaginary colors.
- smallerize 6mo agoBut that's still mixing just a few primary wavelengths.
- jjmarr 6mo agoThe DCT of wavelengths that create the non-spectral colour. No clue how you'd film in this format but the CGI and video games would be epic.
- joquarky 6mo agoMaybe wavelets will make a comeback
