What is HDR?

HDR (Radiance High Dynamic Range) is an image format developed by Greg Ward using the RGBE encoding scheme. It stores floating-point luminance values per pixel, allowing a much wider brightness range than standard 8-bit formats. HDR files are widely used as environment maps (HDRI) for 3D rendering, global illumination, and image-based lighting in software like Blender, Maya, and game engines.
