Show HN: HDR Draw (opens in new tab)

This may or may not work on your device. It requires you have a monitor that supports HDR and a browser that supports WebGPU with HDR support

I mostly wrote it just as proof of concept in that I’m not sure which if any drawing programs, Photoshop, gIMP, Keita, Affinity Photo, or even structured drawing programs like Illustrator or Affinity Design support HDR. Trying photoshop my understanding is it will let you export to HDR and maybe preview in HDR but it won’t let you edit in HDR. Even Lightroom Classic seems to have the same issue even though Macs and iPhones have had HDR displays for 10 years? (Not sure that’s correct).

There are various demos of HDR photography in webpages (chrome only? Tho maybe Safari in iOS/macOS26) and the native photo viewers support HDR but HDR drawing seems missing

also, OSes support HDR but mostly fail to screen capture HDR
