HDR PhotoStudio is a discontinued
high dynamic range (HDR)
graphics application developed by Unified Color for the
Windows and
macOS operating systems. In addition to being a HDR-merge application, HDR PhotoStudio offered a set of
image editing operations that worked in its dynamic range (the website showed an example of processing an image with 1,000,000:1 contrast ratio), human color range (
gamut), and in high precision (32-bit
floating point). It also had a Color Integrity feature that enabled preserving an image's color tone during image editing operations — for example changing an image's contrast would not change its chromatic (color tone) data. This problem is usually referred to as "color shift".

BEF is an HDR
