Show HN: I made an HDR ICC profile for JPG and PNG images
Sample HDR renderings (first few sample renderings): https://bsrender.io
The only viewer/platform I've been able to confirm it works on is the Chrome browser on M1/M2 Macs. It does not work on iPhone or Safari/Firefox on Mac.
The profile is derived mainly from saucecontrol's open source Rec2020Compat-v4.icc profile: https://github.com/saucecontrol/Compact-ICC-Profiles with 'cicp' and 'lumi' tags added. Since it uses the same transfer function as Rec2020, images will appear very washed out/fuzzy on unsupported viewers. I found this "bug" very helpful during testing as it was really obvious if the viewer was using the cicp/lumi tags or the (incorrect) transfer TRC.
With a bit more work you could implement something approximating the PQ transfer function but I actually like the 'you-know-when-it's-not-doing-the-thing' effect.

Optimizing Image Display with Blur Placeholder and Lazyload
blur is a technique to blur images while reducing the file size surprisingly. blur works by enlarging the pixels of the image, which reduces the details of the image, and the number of colors also decreases, thus saving storage space. Sharp is a popular image processing library in Node.js, and it supports the blur function. After going through the blur function, the image size at this point is only a few KB, which is reasonable for an image placeholder in the article.
