Luminance HDR Qtpfsgui – cross platform HDR tonemapping software
Luminance HDR is an open source software designed specifically for HDR Imaging tone mapping. It supports JPEG, TIFF and even RAW files straight from most digital SLR cameras and other high-end point-and-shoot cameras. HDR Imaging, or high dynamic range imaging, is the process of allowing a wider range of luminances between the darkest and brightest areas of a certain picture to display a more accurate representation of intensity levels in real life.
