Radiance Picture, also known as RGBE or Radiance HDR is a lossless raster image format invented by Gregory Ward Larson. Like OpenEXR, it supports high-dynamic-range imaging. Radiance HDR files store colors in 8 bits per component, but with an additional byte for shared exponent.
Each Radiance Picture file contains all the data from all the pictures; so a wide luminance range is present, from bright, white highlights to the darkest black.
