Capture the light of a place.

HDRI Studio turns a guided 26-point iPhone capture — a bracketed burst at each point — into a measured 32-bit OpenEXR you can light any Blender, Unreal or Nuke scene with. No rig, no bracketing math, no desktop.

How it works

From a room to a render, in three moves.

Capture is guided end-to-end. The pipeline handles the exposure ladder, focus and white-balance lock, HDR merge and stitch — so a full 360° takes about a minute of standing still.

01 / Capture

Follow the dots

Aim the crosshair at 26 guided points. The app locks focus and white balance on the real scene, then shoots a bracketed RAW burst at each one. You just hold steady.

02 / Process

Merged & stitched

Your brackets upload to the hosted server, where they’re HDR-merged and stitched into one continuous 360° panorama — no Hugin, no desktop, no bracketing math to get wrong.

A real EXR

Get back a linear 32-bit OpenEXR, preview it in the built-in 360° viewer, and drop it straight in as world lighting.

Earned fidelity

Measured, not invented.

Most phone panoramas guess at what they can’t see and tone-map the light away. HDRI Studio keeps every value your sensor actually recorded — linear radiance, straight through to the EXR. What you light with is what was there.

  • Real linear radiance. Highlights stay bright and shadows stay dark — no cosmetic tone curve baked in.
  • Bracketed for range. Windows, lamps and sky are captured far deeper than a single exposure can hold.
  • Nothing fabricated. No AI fill, no painted-in sky. Where coverage is thin, it stays honest.

Planned pricing at launch

Free to start. Fair to keep.

Capturing, your local library and viewing finished EXRs are always free. A subscription only covers the real server cost of stitching — nothing else is gated.

A “process” turns one capture into a finished EXR on the hosted server — a real cost we pay per job, and the honest reason it’s metered. Capturing, your local library, and viewing finished EXRs never need a subscription. Final prices are set in the App Store and may vary by region.
