Logluv TIFF  From Wikipedia, the free encyclopedia Jump to:
navigation, search  Logluv TIFF is an encoding used for storing
high dynamic range imaging data inside a TIFF image. It was
originally developed by Greg Ward for storing HDR-output of his
Radiance-photonmapper in a time, where storage-space was a
crucial factor. Its implementation in TIFF also allowed the
combination with image-compression algorithms without great
programming effort. As such it has to be considered a smart
compromise between the imposed limitations. It is slightly
related to RGBE, the most successful HDRI storage format, an
earlier invention of Greg Ward.   Logluv TIFF's design solves
two specific problems: storing high dynamic image data and doing
so within a reasonable amount of space. Traditional image format
generally stores pixel data in RGB-space occupying 24 bits, with
8 bits for each color component. This limits the representable
colors to a subset of all visible and distinguishable colors,
introducing quantization and clampi
