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".[1][2][3][4]

HDR PhotoStudio implemented an advanced HDR image compression format called BEF, and a plug-in for opening and saving files in Adobe Photoshop was also included with the application.[5] HDR PhotoStudio was discontinued in July 2010.[citation needed]

BEF is an HDR image format developed by Unified Color. The BEF format can archive image data with any dynamic range, full human color range, and a quality setting directly tied to color data precision; the used techniques ties it with JND — just noticeable difference parameter.[6]
