Glowroom: SDR to HDR Converter

Shot in SDR? Convert it. Already HDR? Relight it. Glowroom turns any photo into true HDR. It synthesizes a real HDR gain map — the same technology behind iPhone HDR photos — so your images glow with brilliant highlights on HDR displays and still look great everywhere else. Glowroom does both, entirely on your device — free and private, no uploads. FIND YOUR NON-HDR PHOTOS Proprietary feature -- Glowroom scans your entire library to discover every SDR (Standard Dynamic Range) photo. Filter by date or device, omit screenshots, and collect them all into a single album with one tap. Your best candidates for HDR conversion.
