A complete open-source workflow for creating, editing, and tone-mapping High Dynamic Range (HDR) images.
Luminance HDR is an open-source desktop application for High Dynamic Range imaging. It provides a complete workflow for creating HDR images from multiple exposures, editing them, and applying tone-mapping to produce viewable results. It solves the problem of needing expensive proprietary software for professional HDR photography and post-processing.
Photographers, digital artists, and hobbyists who work with HDR photography and need a free, comprehensive tool for merging exposures and tone-mapping.
Developers choose Luminance HDR because it's a fully-featured, open-source alternative to commercial HDR software, supporting a wide range of HDR and LDR formats and integrating proven libraries like pfstools for reliable image processing.
