Glowroom

SDR Finder scans your whole library and collects every non-HDR photo into one album — then relight them into true HDR with real gain maps.

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.

Shot in SDR? Convert it. Already HDR? Relight it. 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.
