HDRI StudioSupport
HDRI Studio captures bracketed iPhone photos and turns them into 360° HDR environment maps for 3D and VFX workflows. Here’s how to get help and get the most out of it.
Getting help
Email support@hdristudio.app with your device model, iOS version, app version, and a short description of what happened. Screenshots help.
Processing issues
If a hosted-server job fails, or you need a hosted job deleted early, include the server job ID or EXR filename. Captures and finished EXRs stored on your device can be deleted in the app at any time.
Getting sharp results
The pipeline handles bracketing, focus, white balance and the exposure ladder for you. The wins that are up to you at the shoot:
- Hold dead still at each of the 26 points. Brace your elbows and exhale while it shoots — motion blur baked into a frame can’t be recovered.
- Keep the nearest object about 1.5 m away. Close objects are where handheld parallax shows; stand in open space, away from clutter.
- Pivot around the lens, not your wrist. Turn your body around the phone rather than sweeping it through an arc.
- Hit all 26 points, including straight up and straight down — gaps become stretched poles.
- Keep the scene static. People, pets, blowing curtains or flickering screens can ghost.
Common questions
What do I need? An iPhone. There’s no rig, no desktop app, and no account.
What comes out? A linear 32-bit OpenEXR, equirectangular 2:1, 4K by default — ready to use as world lighting in Blender, Unreal, Nuke, Houdini and more.
Do I need a subscription? No — capturing, your local library, and viewing finished EXRs are always free. A subscription only covers the cost of stitching on the hosted server past the free quota.
Where are my files kept? On your device until you delete them. The hosted server keeps only a small rolling cache (currently the newest 6 jobs); see the Privacy Policy for retention and deletion.
