HDR PhotoStudio

HDR PhotoStudio was an advanced HDR (High Dynamic Range) digital imaging software application developed by Unified Color for Microsoft Windows XP/Vista/7 and Apple's Mac OS X. In addition to being a HDR-merge application, HDR PhotoStudio offered a set of image editing operations that work 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 allowed users keeping an image's color tone during HDR PhotoStudio image editing operations — for example changing the contrast of an image would not change image's 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.
