Luminance HDR, formerly Qtpfsgui, is graphics software used for the creation and manipulation of high-dynamic-range images.

Released under the terms of the GPL, it is available for Linux, Windows and Mac OS X (Intel only).

The software also provides batch processing functionality for creating HDR images and for tone mapping them in a non-interactive way.

For users who prefers the command line, a non-GUI, non-graphical interface is also available on all supported platforms.

If this automation doesn't provide the desired result, the user may improve it manually.
