Luminance HDR – formerly Qtpfsgui – is graphics software used for the creation and manipulation of High Dynamic Range images. It is released under the terms of the GPL and is available for the operating systems Linux, Windows and Mac OS X (Intel only). Luminance HDR supports several High Dynamic Range (HDR) as well as Low Dynamic Range (LDR) file formats.


Prerequsite of HDR photography are digital images with different exposures. Luminance HDR then combines those images and calculates a high-contrast image. In order to view this image on a regular computer monitor, Luminance HDR can convert it into a displayable LDR image format using several methods (tone mapping).

A common problem with HDR photography is that the images need to be aligned exactly on top of each other. If the subject is static, this can be achieved using a tripod or a stable surface on which the camera is placed. In case of image data, that doesn't depict exactly the same, the program allows the function to align the images on top of each other. An automatic alignment is implemented using the Hugin project. If this automation doesn't provide the desired result, the user can improve it manually.

Supported formats[edit]

HDR images are images with a high dynamic range and, using Luminance HDR, they can be created as well as edited. The following HDR graphic formats are supported:

Luminance HDR can create an HDR image from several LDR images and tonemap an HDR into an LDR. The following LDR formats are supported:
