Show HN: Make images render brighter than white by abusing Rec.2100 PQ profiles
Summary
The article explains how an image can appear brighter than a browser's white by embedding a Rec.2100 PQ ICC profile into an 8-bit JPEG. It leverages the headroom between SDR reference white and HDR display peak, using in-browser processing to boost white regions while keeping other content normal. It also notes caveats and the likelihood that platforms will curb this technique over time.
