Radiance HDR
What is HDR?
HDR (Radiance RGBE) is a high dynamic range image format developed by Greg Ward for the Radiance rendering system. It stores luminance values that can represent the full range of visible light, far exceeding the capabilities of standard 8-bit image formats. HDR images are essential in 3D rendering, lighting simulations, and image-based lighting (IBL) pipelines.
