Luminance HDR

Luminance HDR is an open-source graphical user interface application designed to provide a workflow for HDR (High Dynamic Range) imaging. The software enables users to load multiple exposure brackets of a single scene, align them to compensate for camera movement, and combine them into an HDR file. Various tone-mapping operators are included to compress the dynamic range of the combined image so it can be displayed on standard monitors or saved in common image formats.

The application supports numerous file formats, including standard JPEGs and TIFFs, alongside RAW camera files from various manufacturers. Users can inspect histograms, adjust exposure levels, manipulate metadata, and perform cropping operations within the workspace. The software is released under the GNU General Public License and is developed specifically for Linux environments, focusing on providing technical control over the photographic tonal adjustment process.
