iPhone

Capture real light at 26 guided positions using RAW brackets. Export a 4K OpenEXR (.exr), with 8K where available, for 3D, VFX, archviz, and product renders. Turn the light around you into a relative scene-linear, 32-bit OpenEXR (.exr) environment map for image-based lighting, realistic reflections, VFX, archviz, and product rendering. HDRI Studio guides your iPhone through 26 positions around a full sphere and automatically captures RAW exposure brackets when you are aimed and steady. Hosted processing merges the brackets, corrects the ultra-wide lens, and stitches a 360° equirectangular panorama. Save the finished .exr to Files or export it for use in any 3D or compositing tool that supports OpenEXR. No chrome ball, dedicated panorama camera, or capture rig is required.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

This update improves purchase, reprocessing, and camera compatibility. Credit status stays accurate while connectivity changes, reprocessing waits for a verified balance instead of showing a false paywall, and unusable lens calibration data no longer blocks otherwise valid captures.
