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.
