What is HDRI?

HDRI (High Dynamic Range Imaging) is a method used in photography and computer graphics to capture, store, and display a broad range of luminosity levels.

HDRi files (hdr or exr) are 360 degree images that contain accurate lighting information by merging multiple exposures of the same captured environment.

By using an HDRi file in a scene, you can boost the sense of immersion of your 3D models.
