Most people do not search for Ultra HDR—they notice that some photos look brighter and have more pop. LumaGain turns an existing product photo into one compatible JPEG: choose the highlights that should stand out, preview the result, and export. On supported screens and apps, those highlights can look brighter; elsewhere, the same file remains viewable. Built for marketers, creators, and small brands that want more eye-catching product images without learning the display technology.

Could you build this?
Partial The marketing site and canvas mask selector are simple, but synthesizing, encoding, and packaging ISO 21496-1 / Adobe Ultra HDR gain maps into compliant JPEG metadata requires specialized image processing.
What it would actually take: The stack needs a client-side or backend image processing engine (e.g., C++/Rust via WebAssembly or Libvips/Sharp) that creates an SDR base image and calculates a calibrated HDR gain map layer from SDR image highlights. It must correctly format and inject Adobe/ISO Ultra HDR gain map metadata into JPEG MPF (Multi-Picture Format) or XMP namespaces to render correctly across modern Android, iOS, and Chromium displays. The hard part is mastering color spaces (Display P3, Rec. 2020), tone-mapping curve math, and adhering strictly to gain map container specs.
