Certain logos started standing out to me on LinkedIn as brighter/whiter than everything else around them.I dug in and found out this is accomplished by adding a gain-map to an existing JPEG, visible only on HDR screens like a newer MacBook Pro. LinkedIn is the only social network I've found that isn't stripping them out, but of course you serve them up on your own site.I worked with Claude Code to turn it into a little browser-based utility (no registration) and hope you find it useful!Comments URL: https://news.ycombinator.com/item?id=49402521Points: 3# Comments: 0
