Glowroom
Native HDR for any photo — on device
Add native HDR to any photo.
Glowroom turns ordinary (SDR) photos into true HDR that glows on modern displays — by synthesizing a real HDR gain map, the same mechanism iPhone cameras use, not a fake filter. It also relights photos that already have HDR, and includes a full adjustment studio. Everything runs 100% on device — no account, no upload.
Download on the App Store · iPhone & iPadReal gain maps, on device
Builds a genuine HDR gain map for any photo so it earns the HDR treatment in Photos and glows on HDR displays — generated entirely on your iPhone or iPad.
Styles & strength
Four looks — Balanced, Dramatic, Punch, Airy — with a strength control and a live glow preview.
Build on existing HDR
Photos that already carry a gain map can be strengthened or softened with a single centered control.
Full adjustment suite
Apple-grade Auto enhance, a Levels histogram with draggable black/mid/white handles, plus Exposure, Contrast, Highlights, Shadows, Saturation, Clarity, Dehaze, Sharpness, Temperature, Tint and Vignette.
Your non-HDR photos
Scans your library on-device for photos without HDR — filter by year, device and screenshots, then work through them.
Save your way
Save as a new photo or update the original reversibly (Revert to Original any time). Works directly inside Photos via the editing extension.
