Oloneo PhotoEngine is a popular digital image editing software application developed by
Paris-based Oloneo SAS.[1] The application produces
high-dynamic-range images and
tone mapped images by programmatically combining standard-dynamic range images of different exposures. PhotoEngine supports 96-bit per pixel HDR image files in RAW and TIFF formats.[2][3][4][5][6]
The software, developed by Oloneo's president Antoine Clappier, was first beta released in July 2010.[7]
