OpenGL mandates support for an analogous RGB9_E5 color (not render) format, where three channels have 9 bits of mantissa each and share 5 bits of exponent. [2] JPEG XT Part 2 (Dolby JPEG-HDR) and Part 7 Profile A are based on the RGBE format. RGBM is a format with the exponent replaced with a shared multiplier, while RGBD stores a divider instead.
If you merely convert a JPEG to a PNG, your graphics program will likely produce one of these true-color PNGs, and make a large file. You should convert such PNGs to "indexed" or "palette-based" mode before you upload them. Most raster graphics editors will let you convert from true-color mode (also called "full color" or "RGB"), and let you ...
The use of high-dynamic-range imaging (HDRI) in computer graphics was introduced by Greg Ward in 1985 with his open-source Radiance rendering and lighting simulation software which created the first file format to retain a high-dynamic-range image. HDRI languished for more than a decade, held back by limited computing power, storage, and ...
English: A 3D rendered image using path tracing, rendered by Blender's Cycles renderer. The smoothness of the meshes used for the cows has been increased using subdivision . The scene uses very simple lighting, and uniform background colors, to make it easier to interpret differences in global illumination when comparing to versions of the ...

High dynamic range imaging (HDRI) refers to the set of imaging technologies and techniques that allow the dynamic range of images or videos to be increased. It covers the acquisition, creation, storage, distribution and display of images and videos.
Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.
Thus a truecolor PNG is typically larger than a color-reduced GIF, although PNG could store the color-reduced version as a palettized file of comparable size. Conversely, some tools, when saving images as PNGs, automatically save them as truecolor, even if the original data use only 8-bit color, thus bloating the file unnecessarily. [ 55 ]
