). 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". 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. HDR PhotoStudio was discontinued in July 2010. BEF is an HDR

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.
